Temperatures “remaining around normal” for rest of week as wet weekend looms

Heatwave forecast Ireland

Highs of 24 degrees are still possible, but prepare for rain.

Friendship ended with the heatwave. Now normal temperatures are my best friend.

It’s been a heavy few days out there. Monday brought the hottest temperature recorded in Ireland in the 21st century of 33.0 degrees, the joint second-highest temperature ever recorded in the country, and the hottest Dublin has ever experienced.

Across the water on Tuesday, parts of the UK reached 40 degrees Celsius for the very first time. Wildfires broke out in Ireland, the UK, Spain and France, leading to significant scenes of devastation.

Meanwhile, a stark warning has been issued by the Climate Change Advisory Council, stating that Ireland is “not prepared for today’s climate” and that “the climate of the future is set to get much worse with more frequent and extreme heatwaves, flooding and coastal surges”.

For now, however, the heatwave, brief as it was, appears to be over.

Not only that, but a wet weekend is on the cards, per the latest forecast from Met Éireann. Temperatures are set to “remain around normal” for the remainder of the week, according to the national forecaster. Although, it’s maybe not as dramatic a shift as it first sounds.

Wednesday has already started out cooler and cloudier than the past few days, and some scattered showers are anticipated. It should prove mainly dry by late afternoon, with varying cloud and sunny spells for company. Maximum daytime temperatures will range from 15 degrees in the northwest to 21 degrees in the southeast.

Wednesday night will stay mostly dry aside from isolated showers in the north. Lowest temperatures of 9 to 13 degrees and there may even be some patches of mist and fog in northwest.

Thursday will bring a mix of dry conditions and some possible light showers, mainly in the north and west. Heavier showers may emerge in the southwest as the evening approaches. Highest daytime temperatures will range between 15 and 20 degrees, lowering to between 11 and 14 degrees at nighttime.

Friday, meanwhile, offers highest daytime temperatures of 18 to 22 degrees amidst warm sunny spells and a few light passing showers across the south and west of the country. Friday night changes the game a bit with rain and drizzle slowly pushing up from the southwest, with “heavy bursts” possible along with lowest temperatures of 11 to 16 degrees.

Into the weekend and perhaps more traditional territory for an Irish summer. Saturday will be “a rather wet day”, according to Met Éireann. Outbreaks of rain and drizzle will travel up across the country, heaviest and most persistent in the west and north. Sunny spells are also possible, too.

Expect a a warm and humid mix, with highest temperatures hitting between 18 and 23 degrees, warmest across the midlands and the east. Saturday night will bring further falls of heavy rain and very mild and humid conditions.

Sunday will be a “breezy” day with scattered outbreaks of rain – though some warm sunny spells are also forecast. Highest temperatures of 17 to 24 degrees, best across the eastern half of the country.
