Ireland On Fire: 25 Degrees And Not A Cloud In Sight
Ireland in the middle of May feels more like a continental summer than anything Irish. Saturday 17th May delivers yet another scorcher with zero rain, cloudless skies, and temperatures pushing 25 degrees in the west. From Donegal to Kerry, Ireland remains stuck in a hot, stagnant loop that’s raising serious questions. While the east remains slightly cooler near 17°C, that’s still well above spring norms. Conditions are dry. Humidity is low. And unless something shifts, this could be one of the driest stretches in years.

Today’s Overview in Ireland
Saturday kicks off with barely a cloud in the sky. By midday, the heat builds quickly, particularly in western counties. Galway, Clare, Kerry and Limerick are expected to bake under intense sun, with temperatures touching 24 or even 25 degrees. The midlands follow close behind. The east coast, from Wicklow to Louth, will stay a touch cooler thanks to marine influence, but even Dublin will see a strong 18 degrees under full sunshine.
Air quality remains fair, and there is little to no wind to shift conditions. This stillness is what’s making this spell feel endless. While it sounds like paradise for beachgoers and tourists, it’s spelling trouble for the agriculture sector. Field moisture is evaporating. Crops are stressed. Farmers across the west are now calling for rainfall projections and backup measures.
Tonight’s Forecast
Tonight will follow the same calm script. Clear skies dominate, and while inland areas may see some brief mist formation, no significant fog is expected. Lows will range from 4 to 10 degrees, with most areas holding mild overnight warmth. Winds stay variable, shifting lightly from northeast to calm.
What You Should Know
Met Éireann has issued no formal warnings yet, but the long-term picture is concerning. UV levels are extremely high between noon and 4 p.m., and healthcare professionals are urging people to cover up, hydrate, and avoid the sun where possible.
With another weekend of unbroken heat on the books, water authorities are monitoring reservoir levels across multiple counties. Gardening bans, hosepipe restrictions and farm supply controls may not be far away if this continues into next week.
Tourism, however, is thriving. Coastal towns are packed, beaches are bursting, and hospitality is booming. But even that brings concern—many holiday areas are now dealing with footfall levels usually seen in late July.
Looking Ahead
Sunday’s forecast brings more of the same. Dry, sunny, and warm. High pressure remains firmly in place with no real sign of breakdown until possibly late next week. Until then, prepare for more heat, dry land, and endless blue skies.
