Ireland Weather Report – Monday 19 May 2025
It’s Monday 19 May and the calm has cracked. While the morning begins with deceptive brightness across much of Ireland, this short-lived serenity will rapidly dissolve.

Temperatures will range drastically from a chilly 15°C in the east to a sweltering 22°C in the west. Brace for a turbulent turn in Ireland’s already unhinged May weather.

Today’s Overview in Ireland
This morning starts deceptively serene with sunny spells and light breezes across much of the country. But by midday, showers will build up quickly—starting along the east coast before spreading westward. Isolated thunderstorms are expected in Connacht, Munster and the Midlands, with real risk of spot flooding due to heavy bursts.
Temperatures are split, with the east lingering around 15°C under lingering cloud, while the west roasts up to 22°C. That gradient is fuelling unstable air and storm development. Roads in rural areas may become slick or even briefly flooded. The weather’s dual nature today will catch some off guard—sun cream in the morning, umbrellas by afternoon.
Tonight’s Forecast
By nightfall, most showers will fade. Skies will offer clear breaks across large parts of the country, with just the odd isolated shower persisting in the southwest and parts of the Midlands. Temperatures will drop sharply to between 3°C and 8°C. Winds will remain light and variable, allowing any developed mist to settle in low-lying areas overnight.
What You Should Know
This sudden storm risk following a long dry spell poses dangers for road users, outdoor workers, and those in flood-prone zones. Lightning, while scattered, is expected to be intense in affected areas. Farmers and construction crews should take precautions with exposed machinery.
Met Éireann has not yet issued formal warnings, but advisory alerts remain in place, especially where localised flooding or lightning may disrupt activity. UV levels remain moderate before clouds increase, so brief early exposure still warrants protection.
Looking Ahead
Tuesday is expected to be less volatile, though still unstable in the west. Isolated showers may linger, but temperatures will hold steady. However, the high-pressure block that brought last week’s dry spell is officially gone. That opens the gates for more volatile Atlantic systems to reach Ireland by midweek.
Be ready for a return to regular chaos: rain, wind, and uncertainty.
