Ireland Weather Report – Blistering Heat—And It’s Only May
Ireland is boiling. Forget drizzle, forget damp—today is sun-soaked and uncomfortably hot for many, especially in the west. The summer surge has landed early and it’s not backing down. This is Thursday, 15th May 2025, and Met Éireann has confirmed one of the warmest days of the year so far, with national highs flirting with 25 degrees and no rain relief in sight.
| Region | Morning Conditions | Afternoon Conditions | Evening/Night Conditions | High Temp (°C) | Low Temp (°C) | Wind |
|---|---|---|---|---|---|---|
| Dublin | Clear and sunny | Sunny, light breeze | Dry, cooling slowly | 20 | 9 | Light easterly |
| Cork | Sunny and warm | Dry and hot | Clear skies | 25 | 10 | Variable breeze |
| Galway | Bright and clear | Very warm, cloudless | Dry and calm | 24 | 8 | Light northeast |
| Limerick | Sun-drenched morning | Hot and dry | Dry with light wind | 24 | 9 | Light variable |
| Belfast | Clear and dry | Warm and pleasant | Mostly clear | 22 | 8 | Light easterly |
| Waterford | Sunny and breezy | Warm with mild haze | Clear and still | 23 | 9 | East to northeast |
| Sligo | Bright and calm | Dry and warm | Cool breeze inland | 23 | 7 | Northeast variable |
Every corner of Ireland is feeling the heat. Sunshine dominates the sky with no meaningful cloud cover and not a drop of rain to be found. The west is sizzling—Galway, Clare, Kerry, and Cork all face maximums hitting 24 to 25 degrees. The heat has settled in early and shows no signs of cooling.
Urban centres like Dublin, while slightly cooler due to coastal breezes, are still registering above 20 degrees with barely a breath of wind. Those along the eastern coast will get only a minor reprieve thanks to a soft easterly flow, but inland, the mercury climbs unchallenged.
TONIGHT’S FORECAST
The evening won’t bring much relief. Skies will remain clear as night falls, giving way to some mist and light fog in rural and sheltered areas. Minimum temperatures will stay mild, between 7 and 11 degrees. Winds will calm down even further, becoming variable and light, allowing the warmth to linger through midnight.
WHAT THIS MEANS FOR IRELAND
Today’s heat is not typical. It’s only mid-May and we’re already brushing up against July-like temperatures. This unusual spike is part of a wider European heat pulse, and Met Éireann is keeping an eye on its persistence. There are no rain-bearing systems in sight, and UV levels are climbing sharply.
People across the country should take necessary precautions. Limit sun exposure during peak hours, hydrate constantly, and check on older neighbours and those vulnerable to heat. Gardeners and farmers may face early soil drying, and those working outside are advised to start early and finish before the afternoon blaze peaks.
There are currently no official warnings from Met Éireann, but forecasters indicate that this heat could be a sign of more persistent high-pressure systems dominating May—raising questions about what June and July might have in store.
LOOKING AHEAD
Tomorrow, Friday 16 May, promises a similar story: dry, hot, and potentially even warmer in the west. As this week wraps up, temperatures will hold steady, and there’s no substantial rain forecast until early next week. Ireland is now in the grip of a prolonged sunny spell that’s fast becoming a talking point for the summer.
