Easter Monday in Ireland: Sunshine, Thunderstorms and Chaos – Full Forecast for 21st April 2025
If you thought Easter Monday would deliver one of those rare beautiful Irish bank holidays, think again. The weather has other ideas, and today promises a chaotic mix of damp misery, brief sunny spells, sudden downpours, and even the threat of isolated thunderstorms. Here’s your ruthless full breakdown of today’s Irish weather forecast.

Today’s Quick Overview
| Weather Element | Details |
|---|---|
| Rain | Clearing northeast by afternoon, scattered heavy showers |
| Thunderstorms | Isolated storms possible during showers |
| Temperature | 11°C to 14°C |
| Winds | Moderate to fresh westerly winds |
| Nighttime | Clear spells with cloud and rain returning from Atlantic coast |
Morning: Dull, Damp and Disappointing
The morning starts off the way Irish bank holidays often do – dull and drenched. Rain and drizzle dominate the north and east, with greasy roads, poor visibility, and a nasty grey start. Temperatures limp into the 8°C to 10°C range early, feeling colder under cloud cover and damp air. Winds are moderate from the west, freshening along the Atlantic coasts, adding an extra layer of chill to the already grim conditions.
Travelers should expect surface water on minor roads and possible delays, especially around rural areas of Ulster and Leinster.
Midday: A Brief, Deceptive Break
By midday, the earlier rain clears away northeastwards, giving a short-lived spell of sunny breaks across the Midlands and southern counties. It’ll feel slightly milder as highs inch towards 13°C or 14°C. But don’t be fooled – lurking instability means showers are already brewing in the Atlantic and along western regions.
It’s a classic Irish “four seasons in an hour” setup: sunshine one minute, black clouds the next, and the inevitable downpour moments later.
Afternoon: Thunderstorms Take Over
From early afternoon, scattered showers explode across the country. Some will be heavy, and isolated thunderstorms are on the cards, especially over Connacht, Munster and inland Leinster. Expect sudden, intense bursts of rain, hail in a few spots, and the odd clap of thunder. Flooding risks rise temporarily where heavy showers repeatedly hit the same areas.
Winds from the west gust moderate to fresh across much of the country, especially along exposed coastal and higher ground areas.
If you’re venturing out for any Easter Monday parades, beach trips, or sports events – bring the waterproofs. And maybe the wellies. You’ll need them.
Evening: Short-Lived Calm Before New Rain Moves In
Later in the evening, most showers die away, leaving clearer spells across many areas. However, the Atlantic is already lining up the next assault. Cloud thickens along the western seaboard with patchy rain moving into counties like Galway, Mayo, Clare and Kerry towards midnight.
Temperatures drop sharply under clearer skies inland, with overnight lows of 1°C to 6°C. Light southerly breezes mean a chilly, misty night ahead for most.
Coastal Conditions: Atlantic Rage Building Again
Surf and boating activities should proceed with caution. Fresh to strong westerly breezes whip up rough seas along the west coast. Tide surges will remain moderate today but expect rougher conditions into early Tuesday.
