Wednesday, 6 August, 2025 __ Forecasts for Ireland

TRENDS ... Generally dry in south and east, occasional light rain today and again around Saturday in west and north, but otherwise also relatively dry there, temperatures gradually increasing to reach mid 20s at times next week.

FORECASTS

TODAY will be partly cloudy with overcast skies further west, leading to outbreaks of light rain by afternoon and evening, amounts generally small away from the northwest coastal counties. Highs 18 to 22 C.
TONIGHT occasional light rain tapering off to drizzle by morning, lows near 12 C.
THURSDAY variable cloud, sunshine at times, highs 18 to 21 C.
FRIDAY cloudy with sunny breaks, a bit warmer, lows near 13 C and highs 19 to 23 C.
SATURDAY occasional light rain in west and north, eventually giving a brief interval of rain further east also, lows near 15 C and highs 20 to 23 C.
SUNDAY partly cloudy, warm, lows near 14 C and highs 21 to 24 C.
MONDAY and TUESDAY will be quite warm with highs into the mid 20s inland south and east. Warm and generally dry for a few days then more unsettled towards end of next week.

My local weather on Tuesday was sunny, hazy and very warm with highs around 29 C.

Thursday, 7 August, 2025 __ Forecasts for Ireland

TRENDS ... Rather cloudy, slight amounts of rain from time to time but for the south and east very little total accumulation, temperatures near average but slowly edging upward into next week.

FORECASTS

TODAY will be cloudy with a few sunny breaks developing by afternoon, as scattered areas of drizzle move off to the east. Highs 17 to 20 C.

TONIGHT partly cloudy to overcast, lows 12 to 14 C.

FRIDAY cloudy with a few sunny breaks, low cloud, drizzle and fog possible near northwest coasts. Highs 17 to 20 C.

SATURDAY a few outbreaks of light rain from a weak frontal system moving across the country, 1 to 3 mm of rain is expected. Lows near 14 C and highs near 20 C.

SUNDAY partly cloudy, hazy and a bit warmer, lows near 15 C and highs near 22 C.

MONDAY and TUESDAY still looking rather warm as heat builds up over France and southern England. There could be some isolated showers or thunderstorms along a weak front lying east-west through Ulster and north coastal Connacht during this warmer spell. Highs could reach 23 to 26 C. Some chance also that this will continue on a few days longer but eventually a more unsettled interval will develop.

My local weather on Wednesday was overcast with a steady light rain that gave about 10 mm, helping to douse a few minor forest fires that started up from the lightning in recent days. It was rather cool for mid-summer here, around 20 C. Tropical Storm Dexter has formed north of Bermuda and is tracking gradually towards Europe but current model guidance suggests Dexter will be too weak to push through the developing ridge bringing the warm spell early next week, and will be confined to an area between the Azores and France where it will likely just die out.

Friday, 8 August, 2025 __ Forecasts for Ireland

TRENDS ... Rather cloudy, only small amounts of rainfall and temperatures slowly increasing to a peak around Tuesday of next week in the mid 20s.

FORECASTS

TODAY will be cloudy with some brighter intervals in the south and east, and occasional patchy drizzle further north, highs 18 to 21 C.
TONIGHT cloudy with some clear breaks revealing a full moon low in the south, lows 11 to 14 C.
SATURDAY mostly cloudy, passing light showers as a weak frontal system drifts east across Ireland, 1-3 mm at most from this, and highs around 19 or 20 C.
SUNDAY hazy sunshine at times, a little warmer, lows near 14 C and highs 19 to 22 C.
MONDAY and TUESDAY look quite warm with some sunshine in most areas, isolated showers mostly in northern counties, and highs 22 to 25 C.
WEDNESDAY variable cloud, still relatively warm at 22 or 23 C.
Temperatures seem likely to maintain this slightly warmer than average trend to about the following weekend (16th-17th) and then it may turn a bit more unsettled, although the trends are rather weak and it could just stay warm for another week.

My local weather on Thursday brought another day of unseasonably cool and damp weather with a bit of rain at times in the morning, and again late afternoon, highs only around 19 C. We are expecting it to warm up considerably through the weekend into next week with 30s returning.

Saturday, 9 August, 2025 __ Forecasts for Ireland

TRENDS ... Becoming warmer for several days next week, generally small amounts of rain but rather cloudy, sunshine improving gradually through the week.

FORECASTS

TODAY a weak frontal system will continue to bring a brief interval of showers as it progresses further south and east, but by afternoon it may begin to lose definition and not all locations in the south or east will see rain at all. Some sunshine at times both before and after the passage of this front. Highs 18 to 22 C.
TONIGHT clear intervals, lows 10 to 13 C.
SUNDAY hazy sunshine, except for more cloud and a slight chance of rain at times in northwestern counties. Warmer, highs 21 to 23 C.
MONDAY and TUESDAY will be hazy and very warm days for most, a slight risk of local thunderstorms developing both in Ulster and parts of south Leinster, but many places will stay dry both days, with highs 22 to 26 C. Overnight lows quite warm also at 13 to 17 C.
WEDNESDAY and THURSDAY little change despite a somewhat fresher wind from the west, sunny intervals, warm with highs 21 to 24 C. Some rain may arrive from northwest by later Thursday, and that may persist into FRIDAY with highs near 21 C. Some uncertainty about details but likely to become more unsettled in stages by weekend of 16th-17th.

My local weather on Friday improved to sunshine and highs near 25 C. Hot weather is moving in for several days now as is generally the case all across the western half of the continent. It is also turning quite warm further east after a relatively cool start to August.

Sunday, 10 August, 2025 __ Forecasts for Ireland

TRENDS ... Rather warm and humid with small amounts of rain at times, trending to moderate amounts in the north. A drier and continuing warm regime will set in after mid-week.

FORECASTS

TODAY will be warm and humid with considerable high cloudiness but spells of hazy sunshine in the south and east. Occasional rain will develop across the north later. Highs 19 to 23 C.
TONIGHT hazy, muggy with lows 12 to 15 C.
MONDAY variable cloud, warm and humid, some further showers and isolated thunderstorms mainly in northern counties, highs 20 to 25 C.
TUESDAY partly cloudy, warm and humid, showers and thunderstorms mainly in west and north, lows near 16 C and highs near 24 C.
WEDNESDAY a few showers as weak remnants of former Tropical Storm Dexter drift across central counties, lows near 17 C and highs near 23 C.
THURSDAY sunny intervals, warm, highs near 22 C.
From Thursday to about a week thereafter, high pressure will be stronger near Ireland and a slight northeast flow will develop at times, making it likely that the west will be warmer in general, but all locations should be at least near 20 C if not into the low or mid 20s at times, with more sunshine than in this current humid spell.

My local weather on Saturday was sunny and hot with the high reaching 33 C. A full moon is visible outside my window looking southeast at present.

Monday, 11 August, 2025 __ Forecasts for Ireland

TRENDS ... Warm and humid, occasional scattered showers and isolated thunderstorms but fairly dry in general, somewhat better sunshine likely towards weekend and into next week, staying warm then also.

FORECASTS

TODAY will be cloudy with a few sunny breaks, quite warm and humid, with persistent light rain across Ulster and parts of north Connacht and the north midlands. Isolated showers further south also, but longer dry intervals. Highs 21 to 25 C.

TONIGHT will be partly cloudy, warm and humid with a few showers, lows 13 to 17 C.

TUESDAY will be partly cloudy to overcast, warm and humid, with a few showers and isolated thunderstorms. Highs 22 to 26 C.

WEDNESDAY variable cloud, a few showers and isolated thunderstorms, lows near 17 C and highs near 24 C.

THURSDAY sunny intervals developing, warm. Lows near 15 C and highs near 24 C.

FRIDAY and on through the weekend into the following week, largely settled and very warm, a few widely scattered showers and isolated thunderstorms possible with weak frontal systems trying to push up from the south at times. Highs generally in 23 to 27 C range, nights quite warm also (13 to 18 C).

My local weather on Sunday was sunny with a few cloudy intervals and hot, with a strong breeze at times especially after sunrise, possibly some decaying thunderstorm cells dropped down from higher elevations then, but no active weather was left, beside the quite gusty westerly winds that subsided after a few hours. Highs were into the low or mid 30s across the region.

M.T. Cranium

Tuesday, 12 August, 2025 __ Forecasts for Ireland

TRENDS ... Very warm, some sunshine each day and improving amounts by weekend and next week.

FORECASTS

TODAY will be hazy and very warm, some sun and a few cloudy intervals, showers and isolated thunderstorms mostly over western and northern counties, possible elsewhere too. Highs 23 to 27 C.

TONIGHT muggy and partly cloudy, lows 13 to 17 C.

WEDNESDAY cloudy with sunny breaks, very warm, showers and isolated thunderstorms but some places will remain dry. Highs 23 to 26 C.

THURSDAY cloudy to start, sunshine will develop mid-day and afternoon. Lows near 15 C and highs near 25 C.

From FRIDAY on into weekend and next week, a prolonged warm spell now seems likely with highs continuing in the range of 23 to 27 C, and nights quite mild at 12 to 16 C.

My local weather was sunny and hot with a high of 35 C. Thankfully the humidity is very low and it cools down quickly at sunset. Most of a full moon is again visible rising in the east-south-east. Will check out Perseids later but light interference from moon is going to diminish the spectacle (if any), will hope for a continuation of the meteor shower into tomorrow evening with an extra hour of moonless viewing then.

Wednesday, 13 August, 2025 __ Forecasts for Ireland

TRENDS ... very warm and humid, some locally heavy showers and thunderstorms but generally dry after today and tonight.

FORECASTS

TODAY will be very warm and humid with increasing cloud followed by outbreaks of heavy showers and thunderstorms most likely from west Munster into the midlands and eventually east Ulster. Some other counties could remain dry. Highs 22 to 27 C.

TONIGHT warm and humid, a few more showers and local thunderstorms, lows 13 to 17 C.

THURSDAY variable cloud, showers dying out, sunny intervals and very warm later, highs 23 to 27 C. From FRIDAY into weekend and much of next week, continued partly cloudy to sunny, very warm, isolated showers but many places staying dry. Lows generally 13 to 17 C and highs 23 to 27 C.As winds turn gradually more east to northeast in this prolonged warm spell, there will be a tendency for highest temperatures to be found near inland west coast locations and in the midlands, but this tendency may not be fully apparent until Friday and thereafter.

My local weather on Tuesday was sunny and very hot with highs close to 40 C. We have one more day of this before a gradual cooling trend with showers replacing the cloudless skies by Thursday here.


M.T. Cranium

Thursday, 14 August, 2025 __ Forecasts for Ireland

TRENDS ... Very warm and rather humid for several more days, isolated showers, but many places will remain dry through most of the interval.

FORECASTS

TODAY will start off rather cloudy in places with scattered showers and isolated thunderstorms. By afternoon this activity will have died out and more sunshine is likely. Highs 23 to 27 C.

TONIGHT warm and muggy, lows 13 to 17 C.

FRIDAY and SATURDAY will continue partly cloudy with sunny intervals and very warm highs 23 to 27 C, lows Friday night also in the 13 to 17 C range again.

SUNDAY and MONDAY more cloud than sunshine in places, as a weak frontal trough brings scattered showers and isolated thunderstorms in a moderate southeast wind flow, lows 14 to 18 C and highs 22 to 26 C. Further spells of sunny and very warm weather are likely to follow.

Tracking current tropical storm Erin approaching the Caribbean islands but likely to miss just to their north over the weekend as Erin strengthens to a hurricane. Longer range guidance suggests Erin will become a very strong hurricane northwest of Bermuda but staying well away from land as it passes Newfoundland about a week from now. No strong indications of where Erin might then go, but some guidance suggests a weakened version of it could reach western Europe in about ten days to two weeks from now, so something we are tracking. Other possible destinations for final stages of Erin would include most of the Atlantic basin including the far northern Atlantic.

My local weather on Wednesday stayed quite hot with an increase in cloud and occasional forest fire smoke haze, highs reaching 35 C.

M.T. Cranium

Friday, 15 August, 2025 __ Forecasts for Ireland

TRENDS ... Continued very warm with some sunshine each day, a gradual increase in coverage of showers and local thunderstorms peaking around Tuesday. Turning a few degrees cooler later next week as east to northeast breezes freshen, but still largely dry and relatively warm.

FORECASTS

TODAY will be sunny with cloudy intervals and very warm, highs 22 to 27 C, warmest inland south, midlands.

TONIGHT clear intervals, lows 12 to 16 C.

SATURDAY sunny with afternoon cloudy intervals, one or two showers and isolated thunderstorms developing in west Munster. Highs 22 to 28 C, warmest west midlands and inland north.

SUNDAY and MONDAY similar but the spread of showers and thunderstorms will tend to drift further north each day and one or two of these could be locally heavy. Even so, a lot of places will remain dry, lows 12 to 16 C and highs 22 to 27 C.

TUESDAY some heavier showers and thunderstorms likely over the west, lows near 12 C and highs near 25 C.

WEDNESDAY on, for quite a few more days, sunny and warm although a few degrees cooler than this current spell, especially in Leinster and east Ulster exposed to freshening east to northeast breezes. Lows 8 to 12 C and highs 19 to 23 C, warmest inland west.

Erin still threatens to become a very strong hurricane northwest of Bermuda within a week and its most likely track is towards Iceland and then remnants could affect the weather in Ireland towards end of the month. Details remain sketchy and low confidence at this point.

My local weather on Thursday was sunny with cloudy intervals, a few degrees cooler than the recent heat wave but still quite warm at around 28 C. Rain is moving towards us from the coast where it was heavy at times earlier on Thursday. We could use a bit of rain without lightning to keep local forests relatively moist (fire danger has decreased in coastal regions in past day and was relatively low in eastern B.C. due to rains a week or two ago).


M.T. Cranium

Saturday, 16 August, 2025 __ Forecasts for Ireland

TRENDS … Some locally heavy showers and isolated thunderstorms will begin to develop Sunday and Monday, departing westward on Tuesday, but even so, quite a few locations will remain dry through this interval, and temperatures will stay very warm, dropping only slightly later next week.

FORECASTS

TODAY will be sunny and very warm with a few cloudy intervals, slight chance of an isolated and brief shower in the inland southwest late afternoon or evening. Highs 22 to 28 C.

TONIGHT mainly clear, lows 12 to 16 C.

SUNDAY will be sunny with afternoon cloudy intervals and a few showers over the inland southwest, very warm again, highs 22 to 28 C.

MONDAY little change except for a somewhat wider scattering of afternoon showers and isolated thunderstorms, lows 11 to 15 C and highs 21 to 27 C.

TUESDAY frequent showers in west Munster, partly cloudy with isolated showers elsewhere. Lows near 13 C and highs near 25 C.

From WEDNESDAY on, a slight increase in east to northeast breezes will lead to slightly cooler temperatures at least over Leinster and much of Ulster, highs may settle in around 19 to 22 C there, while staying 23 to 26 C further west. Overnight lows will be in a range of 8 to 12 C. There may be an extended dry spell for any locations not seeing any of the scattered outbreaks of rain in the coming few days after today.

Little change also in the outlook for Erin, still expected to become a major hurricane west and later north of Bermuda, which will receive a glancing blow if current guidance is correct, as will the southeast Newfoundland Avalon Peninsula on the northern flank in about a week's time. The weakening hurricane will become extratropical and linger south of Iceland sending a gradual regime change towards Ireland in the form of spin-off Atlantic fronts and more seasonable temperatures.

My local weather on Friday was overcast and sometimes foggy with light rain or drizzle fairly persistent after a dry morning, highs near 20 C (feeling chilly by evening after our heat wave).

M.T. Cranium

Sunday, 17 August, 2025 __ Forecasts for Ireland

TRENDS … Becoming more unsettled in the southwest mainly for several days but continuing warm and dry elsewhere. Temperatures will fall slightly after mid-week but will remain above normal.

FORECASTS

TODAY some cloud will spread across parts of Munster and south Connacht, leading to isolated showers later, highs 21 to 24 C. Partly cloudy with spells of warm, hazy sunshine elsewhere. Highs 23 to 26 C except in a few coastal locations closer to 20 C.

TONIGHT partly cloudy to clear, lows 13 to 17 C.

MONDAY will be cloudy with some sunny breaks continuing in Leinster and Ulster. Showers and a few thunderstorms will develop more widespread than today over Munster and Connacht, and could spread into a few parts of south Leinster and west Ulster. Highs 22 to 26 C.

TUESDAY the showers and thunderstorms will begin to spread west and out of many parts of central Ireland becoming largely confined to west Munster. Becoming sunny from east to west after the cloud departs. Lows 14 to 18 C and highs 22 to 26 C.

From WEDNESDAY on, it will likely be quite dry with isolated showers in parts of the southwest, and due to an easterly breeze it will turn a bit cooler in Leinster and east Ulster. Even so, temperatures will be quite warm, highs will continue to register 20 to 25 C across the country, warmest inland west. Nights could be a little cooler at 8 to 12 C. That regime could continue for quite some time, as high pressure builds just north of Ireland while strong hurricane Erin continues a gradual motion northeast past Newfoundland trying to push back against the high, and slowly losing intensity as it makes some progress towards north Atlantic waters south of Iceland. Some weak remnants of Erin could eventually reach Ireland about ten days to two weeks from now, but the effects may be rather subtle and confined to northern counties. There's every chance of temperatures remaining above average right to the end of August and into early September, with very little rain in some parts of the country.

My local weather on Saturday kept improving slowly after a foggy and drizzly start; by late afternoon it was partly cloudy and around 23 C. The coming week looks quite warm and dry here. Erin is on track north of Puerto Rico heading for a point 300 miles west of Bermuda, where it will begin to track northeast towards s.e. Newfoundland although only a glancing blow seems likely there, around a week from now. Although it has been very warm in the eastern U.S. for the past week, a somewhat cooler air mass is pushing south from Quebec and Ontario and will bring somewhat below average temperatures to the northeast U.S. in the coming week. It will remain hot and humid in the central states but that is normal for August anyway.

M.T. Cranium

Monday, 18 August, 2025 __ Forecasts for Ireland

TRENDS … After a couple of days of scattered showers and isolated thunderstorms mainly in the southwest, about a week of dry weather will either follow (where it does rain) or extend the ongoing dry spell. The end of this blocked regime is becoming increasingly uncertain as to details of where remnants of Hurricane Erin end up (one would think a hurricane with this name should naturally come to Ireland to retire), with suggestions now that a very weak remnant will be pushed southeast into the Biscay maritime region dying out over northern France. Whether this new solution is going to survive very long is entirely unknown at this point.

FORECASTS

TODAY will be rather cloudy over many regions with showers and isolated thunderstorms breaking out over parts of Munster and south Connacht, possibly extending a bit further east and north. Some sunny intervals will continue in Leinster and Ulster. Highs will generally be 22 to 25 C.

TONIGHT cloudy with light rain at times mainly in the southwest, lows 12 to 16 C.

TUESDAY further showers in the southwest, trending westward over the course of the day, with sunshine beginning to return from the east. Highs 22 to 25 C.

WEDNESDAY variable cloud with some sunny spells, moderate east winds, lows 8 to 12 C and highs 18 to 22 C.

From THURSDAY on, relatively warm and dry weather with southeasterly breezes will continue with highs 18 to 22 C for several days. Nights could be a bit cooler at 6 to 10 C. There may be a slight warming trend back towards 25 C as the wind regime returns to southerly. Eventually some moisture and cloud from remnants of Erin will arrive, whether the new forecast scenario holds up, or equally likely if the track returns to the Iceland-Faeroes sector. Temperatures will eventually level off closer to 20 C.

My local weather on Sunday was very pleasant, sunny with cloudy intervals, and a comfortable high of 24 C.

Tuesday, 19 August, 2025 __ Forecasts for Ireland

TRENDS … Most places will continue dry and relatively warm although down a few degrees from the peak warmth last week. Rain and moderate winds will arrive late Sunday into Monday, latest indications are that Erin will be held off by a faster-arriving Atlantic low, and that will bring the rain and stronger breezes, while Erin dies out near the Azores instead. Even if this changes back to one of the earlier scenarios, the blocking interval seems likely to end around Monday 25th.

FORECASTS

TODAY will be partly to mostly cloudy, with a few more showers in west Munster. One or two isolated thunderstorms are again possible. Highs 22 to 25 C.

TONIGHT partly cloudy, isolated showers, lows 10 to 14 C.

WEDNESDAY partly cloudy with more frequent sunny intervals in east and north, highs near 22 C.

THURSDAY to SATURDAY little change, sunny with cloudy intervals, overnight lows could fall to a lower range of 5 to 10 C, but daily highs will remain near 22 or 23 C, and could edge back up towards 25 C by Saturday.

SUNDAY increasing cloud, breezy, some rain may arrive in south and west. Highs near 21 C.

Details remain sketchy but it is likely to be rather unsettled for several days starting around MONDAY of next week.

My local weather was overcast with light rain at times until mid-afternoon, when the sun broke through and raised temperatures from 15 to near 21 C.

Wednesday, 20 August, 2025 __ Forecasts for Ireland

TRENDS ... Dry and relatively warm to Sunday or Monday, more unsettled next week. Temperatures somewhat cooler in eastern counties at times due to sea breezes.

FORECASTS

TODAY will be cloudy at first, but sunny intervals will develop. Highs near 18 C east to 22 C west, in a light to moderate easterly breeze.

TONIGHT partly cloudy, clear intervals, cool. Lows 6 to 10 C.

THURSDAY sunny with cloudy intervals, highs 19 to 23 C, warmest inland west.

FRIDAY sunny with cloudy intervals, lows 6 to 10 C, and highs 19 to 23 C.

SATURDAY variable cloud, lows near 7 C and highs near 21 C.

SUNDAY increasing cloud, lows near 7 C and highs near 21 C.

The track of extratropical Erin has shifted back on most guidance to a north Atlantic destination, but also the timing is a bit slower, so the pleasant weather may persist well into Monday with a breakdown now more likely to start Monday night into Tuesday. Temperatures will remain 18 to 21 C by day and 10 to 13 C overnight next week as cloudiness increases. Some rain is expected but there are some signs that it may not be very much rain as some influence of the blocking high may linger, blending the Atlantic flow with the drier air to some extent.

My local weather on Tuesday was mostly sunny with a few cloudy intervals and warmer than recent days at around 25 C. Erin at present is northeast of the Bahamas and southwest of Bermuda, heading north and starting to recurve as the strong hurricane gets picked up by the jet stream. A frontal boundary is developing near New York City and it will likely rain for the afternoon and evening hours there, 10-20 mm expected, and moderate northeast winds will develop. A cooler air mass centered over Ontario and Quebec is pushing the frontal boundary as far south as the mid-Atlantic states where it will likely remain for about a week. It will turn very hot in some parts of the west as a ridge builds near the Rockies.

M.T. Cranium

Thursday, 21 August, 2025 __ Forecasts for Ireland

TRENDS … Continued dry, temperatures warmer in west due to easterly winds off a cool Irish Sea … some slight warming for the east by weekend in more of a southerly breeze then. A slow transition to more unsettled weather will follow as distant remnants of Erin spin off some cloud and moisture for Ireland by late Monday into Tuesday and Wednesday.

FORECASTS

TODAY will be cloudy with sunny breaks more frequent by afternoon. Highs near 17 C in east and near 21 C west.

TONIGHT partly cloudy, lows 10 to 13 C.

FRIDAY hazy sunshine at times, highs near 18 C east, 22 C west.

SATURDAY variable cloud, a few light showers in parts of the south and west, lows 10 to 13 C and highs 19 to 23 C.

SUNDAY sunny intervals, warm, lows 11 to 14 C, highs 20 to 24 C.

MONDAY sunny with increasing cloud, becoming rather breezy by afternoon and evening, rain arriving in western counties late in the day, lows 12 to 15 C, highs 19 to 23 C.

TUESDAY variable cloud, showers, breezy, lows near 15 C and highs near 23 C.

WEDNESDAY showers may become heavier as a more organized front arrives, lows near 14 C and highs near 21 C.

THURSDAY 28th to weekend of 30th-31st will be unsettled with outbreaks of rain and east to northeast winds at times, highs only 17 to 19 C.

My local weather became sunny and very warm by afternoon, with a high near 30 C. It's a clear and dark night ideal for stargazing.

Erin remains a strong hurricane now moving northeast to the north of Bermuda which was lucky not to get closer to its core winds of 120 knots. Conditions on Bermuda are closer to tropical storm, with very large swells battering the coast, as is also the case on the U.S. mainland where winds are northeast 20-40 knots. Erin will not approach Newfoundland as closely as earlier model forecasts were suggesting and it will not make much of a northerly turn until it reaches 35W longitude this weekend. Its effects on Ireland will be moderate as it will be just a regular Atlantic low by the time it comes very close to the west coast (by about Thursday of next week).

M.T. Cranium

Friday, 22 August, 2025 __ Forecasts for Ireland

TRENDS ... Generally dry to late Monday, unsettled after that. Temperatures will continue similar to the past week.

FORECASTS

TODAY will be cloudy with sunny intervals, highs near 18 C east to 22 C west.

TONIGHT partly cloudy to overcast, lows 8 to 12 C.

SATURDAY cloudy with a few light showers, and occasional sunny breaks. Highs 18 to 22 C.

SUNDAY partly cloudy, a bit warmer, lows near 12 C and highs 21 to 24 C.

MONDAY partly cloudy, increasing cloud by afternoon, rain arriving in west by evening. Lows near 13 C and highs near 23 C.

TUESDAY occasional rain, some heavier showers possible. Lows near 14 C and highs near 22 C.

WEDNESDAY partly cloudy, showers, lows near 14 C and highs near 21 C.

THURSDAY and FRIDAY (28th-29th) will be partly cloudy, breezy and a bit cooler, lows near 10 C and highs near 19 C.
The outlook for the weekend (30th of Aug to Monday 1st Sep) is for rather cool and unsettled weather but some brighter spells in the mix, highs near 18 C. It will likely turn a bit warmer later into September.

My local weather was sunny and very warm with a high near 30 C.

Erin has moved past Bermuda and is gliding east now near the 40th parallel of latitude. Guidance earlier today was returning to that theme of a southeastward dive for Erin, but the overnight model runs seem to be back to the stall-near-Iceland version of events. The main difference is that the further north Erin goes before falling apart, the warmer it is likely to remain once it turns unsettled.

M.T. Cranium

Saturday, 23 August, 2025 __ Forecasts for Ireland

TRENDS ... After a reasonably pleasant weekend, Monday will see the first signs of a pattern change becoming more unsettled as the week progresses, with remnants of former hurricane Erin parked off the south coast of Iceland, sending waves of moisture towards Ireland; eventually a very weak remnant low will drift down towards Ulster by the end of the week.

FORECASTS

TODAY will start out generally cloudy but sunny intervals will develop, and any showers will be brief and will tend to die out by afternoon over northern counties. Highs 19 to 23 C.
TONIGHT partly cloudy, mild, lows 12 to 15 C.
SUNDAY partly cloudy, any showers will be confined to the outer fringes of the west coast, and even there quite brief. Highs 19 to 23 C except closer to 17 C in some south coast and west coast locations.
MONDAY increasing cloud, rain at times in western counties. Lows near 15 C and highs near 22 C. Moderate southerly winds will develop, 40 to 60 km/hr.
TUESDAY variable cloud, showers, some rather heavy, lows near 14 C and highs near 20 C. Moderate southwest winds. Large swells are expected to break on Atlantic coasts as the ocean waves driven by distant Erin arrive.
WEDNESDAY showers and a few thunderstorms, breezy, cool, lows near 12 C and highs near 18 C.
THURSDAY to SATURDAY will continue rather cool with occasional rain but also a few brighter intervals. Rain may be more persistent in the west and north than elsewhere.
It may improve slightly after that for a few days with more unsettled spells indicated to follow.

My local weather on Friday was sunny and hot with a high of 33 C. It is bone dry and the temperature fell quickly after sunset to a comfortable 15 C outside now. New moon by the way is right about now (0700h 23rd), if the sun were to go dark today you would see the moon just slightly over top of the Sun's north pole (no eclipse this month). Erin is accelerating now and is located about due south of Nova Scotia, Canada, at around 42 deg N. It is heading for an extratropical transition late today or tonight southeast of Newfoundland and will be a powerful low for two more days, sending large waves and swells towards Ireland even though the low will then weaken around 25 W longitude and start drifting north towards Iceland. It will loop around there mid-week and even weaker remnants of it will drift down towards north Ulster around Friday; no cause for concern because by then, the low will be very degraded and all its energy will be dissipated. I suppose with the name Erin it had to reach Irish shores at some point.

M.T. Cranium

Sunday, 24 August, 2025 __ Forecasts for Ireland

TRENDS ... Becoming more unsettled with rain becoming more frequent and temperatures falling back gradually all week.

FORECASTS

TODAY will be partly cloudy and warm, with a few light showers developing by afternoon in western counties, and highs 21 to 24 C.
TONIGHT mostly cloudy, mild, lows 13 to 16 C.
MONDAY some sunny intervals at first, then cloudy with occasional light rain, southerly winds 40-60 km/hr by afternoon, and highs 20 to 23 C.
TUESDAY variable cloud, showers, breezy. Lows near 14 C and highs near 22 C. Large swells and breaking waves likely on Atlantic coasts.
WEDNESDAY breezy with a few showers, lows near 12 C and highs 18 to 20 C.
THURSDAY and FRIDAY partly cloudy to overcast, breezy, showers, highs both days near 17 C, overnight lows near 10 C.
Little change is expected over the following weekend, and it may turn even a degree or two cooler by Monday (1st of September) with a slight warming trend to follow.

My local weather on Saturday was sunny and hot with a high near 34 C. Just before sunrise if you happen to have clear skies, you'll see very bright Venus rising and almost as bright Jupiter higher up in the southeastern sky. Venus is gradually falling back towards the Sun and will be a prominent evening star by the coming spring of 2026. Jupiter is going to become quite dominant in the midnight skies later this autumn, and we will pass it around mid-January.

Monday, 25 August, 2025 __ Forecasts for Ireland

TRENDS … Becoming quite windy at times and unsettled most of the week as distant remnant low of Erin feeds in moisture and also some large swells and waves on Atlantic coasts. Temperatures will drop below average at least in the daytime hours by end of the week although nights will likely stay quite mild.

FORECASTS

TODAY will be cloudy with a few brighter intervals. Rain will push onto the west coast and some distance further east by afternoon, and winds will increase to southerly 40-60 km/hr. Highs near 23 C in eastern counties, 18 to 21 C further west.

TONIGHT variable cloud, showers and isolated thunderstorms. Breezy, lows 12-15 C.

TUESDAY variable cloud, passing showers, windy (southwest 50-70 km/hr), rain heavy at times by late afternoon and evening, as winds ease for a time with the passage of a trough of low pressure. Highs 18 to 21 C.

WEDNESDAY becoming quite windy again, southwest to west 40-60 km/hr, showers or intervals of rain, lows near 11 C and highs near 18 C.

THURSDAY the remnants of Erin will finally reach Irish shores (now appears more likely to be in Clare or Galway), with further showers and blustery winds at times, lows near 10 C and highs near 17 C.

FRIDAY variable cloud, breezy, passing showers, lows near 9 C and highs near 17 C.

SATURDAY showers, breezy, lows near 8 C and highs near 18 C.

It may turn a bit warmer for a few days in the following week but an unsettled theme looks likely to continue, or resume after a brief interval.

My local weather on Sunday was sunny and hot again with a high near 32 C. Higher cloud is beginning to drift in from the south well in advance of some remnants of the monsoonal thunderstorms that could get this far north at some point this coming week, otherwise it looks likely to remain quite warm.

TRENDS ... Quite unsettled for several more days, with temperatures gradually falling to slightly below average values.

FORECASTS

TODAY some heavy rain in Leinster and east Ulster should clear rapidly east, followed by partly cloudy skies and blustery westerly winds 50 to 70 km/hr. More heavy showers will move into the west and spread into central counties later. Highs 16 to 19 C.

It was still 25 C a few minutes ago closing in on midnight here.

Thursday, 28 August, 2025 __ Forecasts for Ireland

TRENDS … Rather cool and unsettled weather with remnants of former hurricane Erin moving past today, followed by a system that includes remnants of Tropical Storm Fernand on Saturday. Any improvement in this pattern will be delayed well into the middle portions of September.

FORECASTS

TODAY will be breezy to windy near coasts, with outbreaks of rain bringing a further 10-15 mm in some locations. Highs 15 to 18 C. Winds southwest to west 40-60 km/hr.

TONIGHT rain or showers, lows near 10 C.

FRIDAY cloudy with a few breaks, passing showers. Highs 15 to 18 C.

SATURDAY intervals of heavy rain from early morning to mid-day, becoming windy again with gusts to 80 km/hr in some coastal locations, with skies partly cloudy to overcast by afternoon, further showers. Lows near 9 C and highs near 17 C.

SUNDAY breezy and cool with showers, winds west to northwest 40 to 70 km/hr. Lows near 8 C and highs near 16 C.

Most of next week will not be as wet, as the storm track shifts further south taking the heavier rain into France and southern England. But it will stay quite cool for time of year, with highs generally in a range of 14 to 17 C.

My local weather was cloudy with some sunny breaks, and still rather warm with a high near 29 C.

Fernand has been a relatively weak 40-50 knot tropical storm following a track similar to Erin (once it formed closer to Bermuda). Its remnants will merge with a second low closer to Newfoundland today, and the combined weather system will close in on Ireland Friday night, strongest portions passing through around 0600 to 0900 hours on Saturday. The remnant low of Erin is now close to Donegal Bay and will drift east today, becoming fully dissipated Friday over the North Sea.

Friday, 29 August, 2025 __ Forecasts for Ireland

TUESDAY partly cloudy, rather cool, scattered showers generally a bit less intense, lows near 7 C and highs 14 to 17 C.

The regime beyond Tuesday will remain somewhat unsettled, with mixtures of cloud and sunshine, and a few showers here and there. Temperatures will remain in the same range for a while; it may get a bit warmer in the week following.

My local weather stayed rather warm despite thicker cloud cover most of the day, just a little weak sunshine through gaps in the overcast, and a few raindrops around the supper hour although not enough to really wet the ground. The high was about 27 C.

Sunday, 31 August, 2025 __ Forecasts for Ireland

TRENDS … Cool and unsettled, windy at times.

FORECASTS

TODAY will be quite windy and partly cloudy with longer dry intervals in east and south. Some showers may be heavy with thunder and hail possible, especially in western and northern counties. Winds southwest 50 to 80 km/hr in exposed areas. Highs 16 to 19 C.
