Forecast for Ireland, 2nd June 2026

Temperatures by day rather below average with unsettled conditions prevalent through the first and second week of June. Relatively mild at night. The signal remains for warmer temperatures by the end of the second week into the third week but good bit of divide in model output on whether it would bring drier weather simultaneously or continue mixed.

TODAY TUESDAY ... Showers, initially heavy especially in the east, with a few sunny spells across Ireland. The shower risk will ease off later in the day with light to moderate westerly winds in afternoon highs from 14C in the north and west up to 18C in the east.

TONIGHT ... Rain arriving in the southwest pushing northeastward through the night into tomorrow morning. Lowest temps getting down to 10-12C mainly.

TOMORROW WEDNESDAY ... After the rain clears northeastward through the morning, there will be heavy showers developing behind that may consist of thunder. Southwesterly winds stronger with afternoon highs of 13C in the northwest to 17 or 18C in the east.

THURSDAY ... Another day of heavy showers that may merge into persistent spells of rain. Shower risk easing during the evening. Gusty westerly winds giving temperatures of only 12 or 13C at best in the west whilst it will be up to 16C in the southeast.

FRIDAY ... Some showers developing through the afternoon across the country but looks less so compared to prior days. West to southwesterly winds easing to light to moderate as well but temperatures disappointing at only 12-15C. Rain arriving into Munster by the evening hours.

SATURDAY ... Rain pushing northeastward through the early hours followed by scattered showers. Quite cool for June with highs of only 10 or 11C in the north and up to 15C in the southeast.

Forecast for Ireland, 4th June 2026

Temperatures below average and rainfall above average for at least the next 8 days with good bit of showers. Always mildest in the east and coolest in the west due to exposure to the westerly flow which will be prevalent almost throughout the period. Still a sign that somewhat warmer conditions will develop from around June 14th/15th but at this current point it's likely to remain on the unsettled side at least at first with this warmer air tropical maritime sourced which usually ends up damp and humid in Ireland apart from the leeward slope of mountain ranges such as Wicklow where the air dries out and those places get more sunshine such as Bray. Maybe a stronger push towards higher pressure by the latter half of the third week.

TODAY THURSDAY ... A classic fare of sunshine and showers, more widespread later in the morning into the early afternoon before easing off as the day goes on. Westerly winds remaining gusty with maximum temperatures ranging from 12C in the west to 16C in the east and southeast.

TONIGHT ... Showers will ease off with clear spells. The wind will also calm down and it will be one of the coolest nights for a good while getting down into the mid single digits, 3 or 4C in the sheltered southeast is possible.

TOMORROW FRIDAY ... Mostly dry at first with some scattered showers and sunny spells. However, rain will develop from the southwest and push northeastwards later in the day through the afternoon. Winds will freshen again and it could be unseasonably windy on exposed southwest coasts Friday night into early Saturday.

SATURDAY ... Rain gradually clearing northeastward, it may take until the mid-afternoon to clear east and northeast coastal areas. Sunshine and scattered showers will follow behind in fresh westerly winds by the evening. Maximum temps from 12C in the west to 16 or 17C in the southeast in some slightly milder air from the south for a time.

SUNDAY ... Significant changes for Sunday compared to yesterday. Whereas it was looking showery and cool, it's now looking like a weather front will linger over the country with a dividing line between cooler air to the west side of it and warmer, more humid air to the east of it. Where it lingers could have a lot of rain and be very heavy occasionally. Details to be firmed up on. Ahead of it in any hazy sunny spells, it could now get up to the high teens in the east with 12-14C at best to the west and northwest. Winds moderate southwesterly in nature.

MONDAY ... Straightforward sunshine and scattered showers as winds veer back to the west. Maximum temps 12-16C.

Forecast for Ireland, 7th June 2026

A relatively cool week ahead for early to mid-June with temperatures below average by day and night at times. Plenty of showers and occasional rain bands passing through. Promise for things to warm up significantly by the weekend into the third week of the month. High uncertainty on if this will be the very warm dry type or relatively warm and humid but still damp kind.

TODAY SUNDAY ... Mostly cloudy with rain spreading eastward. The rain will likely become very heavy with some high rates possible in a short period of time in the east later. Hazy sunny spells at times in the east earlier on in the day. Sunshine and some scattered showers will arrive in the west through the evening. Where the rain cloud lies with some clearance on the western horizon could be a colourful sunset, the midlands most likely. Maximum temps ranging from mostly 13-15C with up to 16 or 17C possible in the sheltered east in moderate southwesterly winds.

TONIGHT ... The last of the rain will clear the east followed by clear spells and some scattered showers. Minimum temps down to 6 or 7C, slightly cooler in local sheltered areas and slightly milder on exposed coasts to southwest to westerly winds.

TOMORROW MONDAY ... A day of sunshine and showers, becoming widespread through the afternoon. Moderate westerly winds giving maximum temps from 12-16C, mildest in the southeast.

TUESDAY ... Another day of sunshine and showers in moderate westerly winds. Similar maximum temps from 12C in the north and northwest to 16C in the southeast.

WEDNESDAY ... Some further scattered showers and sunshine to start the day. More prolonged widespread showers will push southeastward from the north through the morning into the afternoon with good bits of cloud. This will ease off later but more rain possible late Wednesday night into Thursday morning. No change in temperatures ranging from 12-16C.

THURSDAY ... Rain will clear east followed by a return to sunshine and showers. A bit milder but with rather blustery winds at first southerly, veering westerly later. Maximum temps still 12-14C for places but higher teens over Munster.

FRIDAY ... High uncertainty. Could well be another day of sunshine and showers in blustery westerly winds. Alternatively, higher pressure could build from the south with good warm sunshine developing. Watch this space.

Forecast for Ireland, 9th June 2026

Showery and cool to start the period, turning warmer and generally drier over the weekend for a time. The warm and dry period is likely to be transient with more changeable conditions again from next week as high pressure looks flimsy in nature rather than the omega blocking that gave the May warm spell.

TODAY TUESDAY ... Plenty of showers developing during the day in blustery westerly winds with risk of thunderstorms, mainly over the north and northeast. Some sunny spells inbetween and rather cool with max temperatures ranging from 12-16C west to east.

TONIGHT ... Showers will continue, especially to the west and north. Some clear spells too with westerly winds easing making it a cool night for some getting down to 4 or 5C whilst others under cloud will be 6-9C.

TOMORROW WEDNESDAY ... More showers again which will ease later in the day in moderate westerly winds. Some sunny spells as well in max temperatures of similar values from 12-16C. Cloud increasing from the west through the evening hours ahead of rain pushing eastward Wednesday night into Thursday morning which will hold up the temperature.

THURSDAY ... Widespread rain pushing eastward to start the day clearing the east coast by the afternoon. There will be further showers behind with a good bit of cloud for the rest of the day in moderate south to southwesterly winds. Afternoon highs of 13-18C from northwest to southeast.

FRIDAY ... Cloudy early on with some patchy rain and drizzle. Sunny spells developing for the south and east through the day but remaining rather cloudy in the north and west. Temperatures up to 20 or 21C in the southeast whilst still 14 or 15C up north.

SATURDAY ... Rather cloudy still in the north and northwest with hazy sunshine elsewhere during the morning. More frequent sunny spells developing with temperatures responding getting up to 24 or 25C possible in the south and east away from the coast. Closer to higher teens or low 20s elsewhere.

SUNDAY ... Hazy warm sunshine to start the day, cloudy to the west and north with some drizzle possible as winds veer southerly. Max temperatures ranging from 17-25C.

Additional note: The first noctilucent clouds of the season were spotted over Ireland this morning. If you want to observe NLCs which are white glowing clouds in the summer twilight sky, you need to look out around an hour after sunset and an hour to two hours before sunrise to the north if you have clear skies. They are most common before sunrise. They disappear or get fainter lower on the northern horizon for a time as the sky gets darker around midnight to 2am. There's no way of predicting them. Mid-June to mid-July is peak NLC season in Ireland.

Forecast for Ireland, 14th June 2026

A mixed week ahead with large amounts of cloud and winds primarily from the west after a period of easterly winds through today and tomorrow. Rainfall totals for the most part look low with two main periods of wet weather highlighted for Tuesday afternoon focused on the south and east and especially Thursday night more widespread. Milder than last week but more typical values for mid-June than anything that warm. Ridging may build back next weekend again. Some model runs have hinted towards a setup in the fourth week of June that would give a very warm period but the signal is not strong.

TODAY SUNDAY ... Hazy sunshine becoming more widespread through the day after a cloudy start. Some drizzle is possible at first, moreso in the north. The west will be warmest for a change as the wind will veer to the east with low 20s here whilst the south and east coast will be mid-teens. Northern areas in the upper teens. Easterly winds will be rather light in nature but moderate on exposed coasts and to the south of the country.

TONIGHT ... Some clear spells and dry but fair amounts of cloud across the country. Thickest of cloud may produce drizzle. Relatively mild getting down to 10-12C generally.

TOMORROW MONDAY ... Some hazy sunny spells early on with cloud increasing from the west bringing drizzle or light rain eastward. Winds east to southeast at first, veering southwesterly later in the day with max temperatures from 15-20C west to east. Misty and damp Monday night with some drizzle and mild.

TUESDAY ... A cloudy, damp start with some drizzle. Some limited bright spells to the north and west possible before more rain pushes up from the southwest affecting the south and east which might be occasionally heavy. The north and west looks to avoid much of this rain. Southwesterly winds increasing in strength with max temperatures of 15-20C, coolest on south and west coasts and warmest in the east. Clearer spells following into Tuesday night from the southwest.

WEDNESDAY ... A windy but brighter day with some showers, mainly in the northwest. Cloud increasing to the south and southwest later in the day with max temperatures ranging from 15-20C west to east again.

THURSDAY ... Cloud and outbreaks of rain through the day with limited brightness. Winds veering southerly increasing the humidity but the southerly wind will be gusty in nature. More general rain will spread across the country from the west and southwest later in the day through the night which could be very heavy for a time. Max temperatures through the day 15-19C west to east.

A later update this morning but an important one with some details on tomorrow's rain and some changes for the weekend.

Forecast for Ireland, 17th June 2026

Continuing mixed for the week ahead with rain and showers at times. Widespread rain on Thursday could give rise to localised flooding as totals look rather high for some and this rain could last well into Friday for a portion of the country before fresher, drier conditions arrive from the west. The low chance remains of a build in pressure bringing significantly warmer and fine weather next week but the highest likelihood is that it will continue mixed with relatively warm and humid conditions occasionally, moreso for the south and east. This uncertainty begins as soon as Sunday as to where a cut off low will be placed in the Atlantic or the Bay of Biscay.

TODAY WEDNESDAY ... Good bright spells across the country today with some scattered showers, mainly in the west and northwest. A moderate southwesterly breeze with max temperatures of 15C in the west to 20 or 21C in the east. Not a bad day, however cloud will thicken with rain arriving in the southwest later in the day around the early evening hours.

TONIGHT ... Light rain and drizzle will push into the southwest through the evening hours, this won't amount to much. More general persistent rain arriving the early hours of Thursday morning affecting most places with highest totals expected in a diagonal stretch from Kerry and Cork up to Meath/Westmeath. Munster could see over 30-40mm of rain the next 48 hours. This rain will pass over relatively quickly and clear the east coast through the later morning hours but looks heavy in the stretch named. The rain and cloud will keep it mild only getting down to 12-14C for most, a bit cooler in the north where there may be some clear spells for a time.

THURSDAY ... The first of the rain bands will clear eastward through the later morning hours. Further damp and drizzly conditions with a bit of light rain mixed in will continue across Ireland during the day itself before more frequent heavier rain again from the southwest through the later evening hours into the night and highest totals again in similar counties. Humid with temperatures of 15-20C west to east. May even get a little higher if the sun manages to come out in drier periods. Remaining mild and humid into Thursday night.

FRIDAY ... The rain will continue through Friday morning and even into the afternoon for the east of the country with some heavy falls likely again before clearing by the later afternoon hours into the Irish Sea. Brighter conditions will follow from the west with relatively light southwesterly winds and a few showers. Max temps of 15-20C, coolest in the north and upper teens for most places.

SATURDAY ... Now looking like a rather decent day with the previously expected rain no longer signalled. Sunny spells and mostly dry with the odd shower. Maximum temps of high teens for most with mid-teens in the northwest and coastal areas in light variable winds.

SUNDAY ... Uncertainty surrounding a cut off low that may bring rain from the west though not pushing eastward all that far or if higher pressure will be strong enough to fend off this and leave it out in the Atlantic. If so, could be a very pleasant day with sunny spells and warming up to widespread high teens and low 20s. The east is quite likely to be rather fine either way based on current model output.

Forecast for Ireland, 20th June 2026

A warm week ahead with lots of dry weather until next weekend when it's likely to become more volatile with risk of thunderstorms followed by a mixed end to June. Could become notably warm by Thursday and Friday with chance of 30C rising locally.

TODAY SATURDAY ... Mainly dry and fine with sunny spells in light westerly breezes. Small chance of an odd shower. Maximum temps ranging from 15C in the west and northwest to 22C in the east.

TONIGHT ... Dry with clear spells. Some mist patches may develop locally as the wind falls very light. Minimum temps mostly 8-11C, a little cooler in the northwest.

TOMORROW SUNDAY ... Another dry day of sunny spells and winds veering east bringing the warmest conditions for the midlands and mid-west up to 23 or 24C possible. 17-19C on east and south coasts.

MONDAY ... Light rain or drizzle getting close to the northwest but should remain offshore. Some showers also close to the southeast may be thundery, otherwise dry again and warming up further with widespread 20s from north to south in variable breezes. Up to 26C in the mid-west. Monday night onward will be very mild at night not getting below the low to mid-teens.

TUESDAY ... More of an Atlantic flow will give cooler and cloudier conditions to the northwest dropping temperatures back to the mid to upper teens. Warmest conditions transferring to the east where it could be 25 or 26C in hazy sunshine.

WEDNESDAY ... Easterly breeze returns and this could result in temperatures back up to 25-27C in the west whilst the east coast will be 17-22C. Odd chance of a shower, otherwise another day of sunny spells.

THURSDAY ... Very warm with temperatures of 27-30C possible in the midlands and west. Cooler on the east and south coast in the high teens to low 20s. Widespread hazy spells of sunshine but growing risk of thundery showers or thunderstorms. Thursday night could only get down to high teens in many places, an exceptionally warm night.

FRIDAY ... Very warm once again with hazy sunny spells but further threat of thunderstorms from the south with maximum temps widely 24-28C. Coolest at the coast and in the south where cloud cover will be more plentiful.

Forecast for Ireland, 23rd June 2026

Exceptionally warm to hot few days up to Thursday and maybe Friday with high humidity making it feel oppressive at times. Increasing risk of thunderstorms by then with cooler conditions by the weekend taking us back to a typical changeable Irish westerly through the final few days of June into the start of July.

TODAY TUESDAY ... Some cloud this morning will clear with widespread spells of sunshine developing. The temperature will respond with many already around 16-20C this morning and will rise to the mid to high 20s for the south and east whilst it will be high teens to low 20s in the west. Cloud will tend to persist to the northwest with more of a westerly wind today.

TONIGHT ... Cloud building but mostly dry with just some drizzle in spots. Very mild only getting down to 12-18C, warmest in the east and south.

TOMORROW WEDNESDAY ... Cloud will break up through the day with sunny spells developing. The north and northwest again will hold onto cloud for the longest where temperatures will cap in the low 20s. The warmest conditions will transfer to the south and southwest due to more of an easterly breeze picking up with mid to high 20s.

THURSDAY ... Exceptionally warm to hot with growing risk of record-breaking temperatures dependent on how much sunshine there is. 34C cannot be ruled out in the west and midlands. Cooler at coastal and eastern regions but even here temperatures look to be in the mid 20s generally speaking due to how hot the airmass will be. The day is likely to begin sunny but instability will build through the day increasing the cloud cover and perhaps limiting the ceiling on how high the temperature will go, subject to change. This will also give rise to thunderstorms with the northwest (Connacht/Ulster) favoured for the highest likelihood and the risk goes on into Thursday night. Moderate east to southeasterly breezes.

FRIDAY ... It looks like heat could hold on into Friday now with winds becoming southerly. This could mean temperatures up to 28-30C again, moreso in the north and east. Cooler conditions for the west and south due to onshore breeze or more frequent cloud cover from thunderstorms which will continue to have a risk of occurring.

SATURDAY ... Cooler but could still be pretty warm and humid to the east with temperatures still getting up to 24C. Mid-teens in the west. Sunshine is likely to be limited with widespread showers in moderate southerly winds.

SUNDAY ... Sunshine and showers with more typical temperatures for Ireland at this time of year in the 15-20C range from west to east.

Forecast for Ireland, 27th June 2026

Back to normal service of winds predominantly off the North Atlantic bringing rain and showers at times through the next week. Temperatures average for the time of year, may feel cool relatively speaking in the wind especially in the west exposed to it. There is signs that it will start to warm up again with the increasing chance for hot weather to return at the end of the first week into the second week of July courtesy of the Azores High throwing up ridging.

TODAY SATURDAY ... Patchy rain and showers spreading eastward with a good bit of cloud and only limited brightness. Cooler than of late but still rather humid up to 23C in the east and mid to high teens in the west. Southerly to southwesterly winds rather moderate to fresh in nature though these will ease off to an extent later in the day.

TONIGHT ... Significantly cooler night as temperatures down to the low double digits generally speaking, still near mid-teens in the east. Could even get down into single digits under clearer spells. Variable cloud and scattered showers in light to moderate southwesterlies.

TOMORROW SUNDAY ... A day of sunshine and scattered showers. The east and southeast will be favoured to stay dry for longest where there's less chance of a shower. Maximum temps during the afternoon cooler everywhere now ranging only from 15C in the west to 19 or 20C in the east with blustery southwesterly winds again. The showers will ease off into Sunday for most away from Atlantic coastlines with clear spells.

MONDAY ... Mostly dry start with a few scattered showers. Cloud and rain will gather from the southwest during the afternoon pushing northeastward. Persistent rain will clear during the night into the early morning hours but will quickly be followed by some showers. Maximum temps of 16-21C from west to east. Breezy with winds from the southwest.

TUESDAY ... Rain will clear eastward during the early morning hours. Breezy with scattered showers and some sunny spells, a touch warmer for many in the high teens to 20/21C as the wind veers southeasterly for a time. Cooler on the immediate west coast and in the north closer to the mid-teens.

WEDNESDAY ... Cloudy with winds veering southwest and some patchy rain possible, especially up north. Clear spells into Wednesday night. Maximum temps of 15/16C to the south and west with up to 20 or 21C in the east and southeast.

Forecast for Ireland, 30th June 2026

Average temperatures for the time of year for the next few days with driest conditions for the south and east. Some rain or showers will occur everywhere at times until the weekend when high pressure is expected to be more influential close to Ireland into early next week with an increase in temperatures. Recent models have tended to keep this high pressure a little too far south to get more widespread warm sunshine however through the weekend.

TODAY TUESDAY ... Cloud and showers clearing eastward this morning with some sunny spells and further showers following behind. Sporadic thunder possible in the showers. It will become drier from the west overnight. Fresh south to southwesterly winds early on, veering light to moderate northwesterly later. Maximum temps ranging from 16C in the west to 20C in the east.

TONIGHT ... Becoming dry almost everywhere with variable cloud cover and clear spells. Some scattered showers will continue in the north and northeast at times. Winds variable in direction, rather moderate northwesterly generally. Minimum temps ranging from 10C in the west to 13 or 14C in the north and east.

TOMORROW WEDNESDAY ... Mostly cloudy with some rain and drizzle to the west and north. Likely to remain dry for the southeast for most of the day with only drizzle from the thickest cloud. More rain will spread southeastward and become lighter as it reaches the south and east through the evening hours. Maximum temps ranging from 16C in the southwest to 19 or 20C in the southeast.

THURSDAY ... A dry day for most with the odd scattered shower to the north and variable sunny spells through the day. Maximum temps ranging from 15C in the north to 20 or 21C in the south in light to moderate northwesterly winds.

FRIDAY ... Fair amounts of cloud for most with some rain and drizzle in the north spreading southeastward. Warm sunny spells for the south and southeast until the later afternoon hours when cloud builds here too. Up to 22C possible in the sunshine, 16C further north.

SATURDAY ... Damp and rather humid with drizzle. Best chance of any sunshine will be to the south and east where temps could get up to 22C again. 16/17C in the north and west.

SUNDAY ... Further damp conditions with more drizzle and rain, again especially to the north. The south will see the best chance of brightness with temperatures up to 22C.

Forecast for Ireland, 4th July 2026

This'll be a short update. The same weather conditions of the past few days will continue through this weekend into early next week. That is mostly damp conditions with drizzle or light rain in the north and northwest, and best chance of any sunny spells in the south and southeast especially through the afternoon and evening. Then more widespread sunny spells from Tuesday afternoon. Uncertainty remains beyond Wednesday on the placement of an upper level low which could either turn things unsettled or reinvigorate high pressure to our north and east which would in turn force hotter air to come up from the south.

SATURDAY TO MONDAY ... Mostly cloudy mornings to early afternoons. Best chance of any sunny spells will be over Munster and Leinster, especially east Munster to south Leinster. Perhaps more widespread sunny spells by Monday afternoon along the east coast. Unfortunately the north and west will remain on the damp side with drizzle and light rain at times with temperature suppressed around 15-18C due to onshore winds off the North Atlantic from a west to southwesterly direction. Those in sunshine could see temperatures up to 22C on Saturday, 24C on Sunday and Monday.

TUESDAY ... Cloud and drizzle attempting to clear to the northeast early on leaving a sunnier day for most of the country and temperatures warming up into the low to mid 20s away from Atlantic coasts as the wind direction will again mainly be from the west.

WEDNESDAY ... Variable cloud cover and sunny spells with low to mid 20s for most again away from Atlantic coastal areas.
