Ireland’s Forecast for 11 April 2025: Sunshine, Sudden Fog and a Massive Temperature Flip Incoming
Warm, dry, sunny… and also foggy, freezing and potentially hazardous. Welcome to Ireland’s weather on this unpredictable Friday. After a frosty start in some inland counties, mist and fog will clear in most areas by late morning. However, don’t get too comfortable — coastal regions in the west and midwest might stay cloaked in fog much longer, affecting visibility and travel conditions.
While inland regions enjoy stunning sunshine and possibly summerlike highs of 22 degrees, fog-stubborn spots will remain several degrees cooler and dull. This classic weather split is being caused by stagnant high pressure and a slack breeze direction that leaves local microclimates to do their worst.
The good news? Most of the country will remain dry with clear skies and gentle southerly or variable breezes. But be warned — the temperature crash tonight could bring frost to rural counties as thermometers plummet to between 0 and 6 degrees.

Tonight’s Breakdown
As darkness falls, conditions become variable again. Skies will remain mostly clear, but areas of mist and fog will return in pockets across the country — potentially becoming dense by early Saturday. Rural inland counties may experience sharp ground frost with lows dipping to 0 degrees, while coastal locations should remain slightly milder.
There is no rain in the forecast, and wind conditions remain negligible with only light easterly or variable breezes expected. The biggest risk tonight is visibility — so drivers should prepare for sudden drops on rural routes.
Travel, Health & Visibility Risks
- Fog could linger longer in coastal zones — especially Galway Bay, Shannon Estuary and parts of Kerry and Clare. Motorists should be on high alert during early hours and post-sunset.
- With highs near 22°C, UV levels will start to rise. Apply sunscreen if you’re out for long periods, especially between 12–4pm.
- Expect a dip back to freezing tonight in isolated rural locations — so gardeners and farmers should protect sensitive crops.
- Coastal sea fog may affect drone pilots and those in marine zones — check visibility and wind advisories if heading offshore.
We’re entering a sharp contrast phase in Irish weather. While most areas will revel in a springtime glow, the country’s edges are still playing by winter rules. Temperatures are surging, but the threat of fog and frost remains. This is Ireland – sunshine meets sabotage, every single day.
