Ireland Weather Report – Friday 16 May 2025
It’s Friday the 16th of May and the heat hasn’t gone anywhere. Ireland is locked in an unnaturally dry, sun-drenched pattern that’s leaving fields brittle and streets blazing. There’s barely a breeze. Met Éireann confirms highs today ranging from 17 to 24 degrees, with the midlands, west and southwest leading the heat charts. There is no rainfall in sight and skies are so clear it feels eerie. We’re heading deeper into a pressure-cooked May, and there’s no sign of a cooldown on the horizon.

Today’s overview
Ireland is under siege from a high-pressure system that refuses to break. Today will see almost every county bathed in unbroken sunshine. UV levels are high, humidity is low, and the land is bone dry. From Donegal to Kerry, people are waking up to yet another scorcher with no meaningful rain on the radar.
The warmest temperatures will hit across the midlands and southern counties, with parts of Limerick, Clare and Cork soaring to 24°C. Eastern and northern regions, though slightly cooler, are still facing well above-average May heat. The air is still, the breeze is almost non-existent, and cloud cover is nowhere to be found.
The east coast, particularly Dublin, sees slightly reduced peak temperatures due to light coastal winds, but the overall experience remains warm and dry. If you’re indoors, you’ll feel the heat building. If you’re outside, prepare for relentless sun exposure from morning until sundown.
Tonight’s forecast
The heat lingers into the evening with skies remaining clear across the country. Mist and fog patches will develop overnight, especially in sheltered inland areas. Temperatures will dip to between 4 and 9 degrees, but even the night will feel dry and still. Winds will stay light and variable with no major shifts expected.
What to know
There’s increasing concern among farmers, rural communities and environmental groups about the lack of rainfall this week. Soil moisture levels have dropped significantly in some counties, and early signs of drought stress are appearing in agricultural land.
Health professionals are warning the public to stay hydrated, wear sunscreen, and avoid prolonged exposure during peak hours. The UV index today is notably high across all regions, especially between 12 p.m. and 4 p.m. SPF 30+ is no longer optional—it’s essential.
Despite the lack of any official Met Éireann warning, this prolonged dry spell is starting to impact water supply conversations in certain counties. If the current pattern continues through the weekend and into next week, we could see local restrictions and agricultural alerts issued.
Looking ahead
Saturday continues the sun-drenched saga with highs remaining in the low to mid-20s. No rain is expected over the weekend, and the high-pressure system dominating over Ireland remains locked in place. If you’re planning any outdoor activity, now is your window—though with caution. Sunday may bring isolated cloud in the northwest, but still no meaningful relief.
