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.
