Mayhem on May 1st: Thunder Rolls In as Temperatures Soar
The first day of May in Ireland brings a taste of summer and a touch of chaos. From sizzling sunshine in the south to rumbles of thunder across the west, the country’s weather is split between a calm start and an unpredictable afternoon. According to Met Éireann, today is shaping up to be a rollercoaster of warmth, wetness, and potentially severe thunderstorms. Here’s your no-nonsense breakdown of Ireland’s weather for Thursday, 1 May 2025.
National Weather Overview
| Region | Morning Conditions | Afternoon Outlook | Highs (°C) |
|---|---|---|---|
| North | Cloudy, misty, scattered rain/showers | Turning sunnier later | 13 – 17 |
| West | Cloudy, localised thunder & mist patches | Sunnier spells, but showers remain possible | 14 – 17 |

Detailed Forecast Today
Begins in typical Irish fashion – a little bit of everything. The north and west will wake to overcast skies, with rain, drizzle and patchy mist. A few isolated thunderstorms are possible across exposed areas. Thankfully, brighter conditions will begin to break through in the afternoon, offering some much-needed relief.
In the south and east, early risers will enjoy sunshine and dry conditions with only isolated fog patches. But don’t get too comfortable. Cloud will gradually build from late morning and by the afternoon, showers – some of them heavy or even thundery – are expected to develop, particularly in southern counties.
Temperatures are the big story of the day. A surge in daytime heat will push highs into the mid-20s across parts of the country, especially in areas that escape the cloud and storms. Expect 18 to 24 degrees across much of the south and east, with cooler temperatures of 13 to 17 degrees where cloud lingers in the north and west.
Winds will remain light from the north, occasionally reaching moderate levels. However, thunderstorms could bring gustier, unpredictable conditions for short spells.
Tonight
Any showers and storms will fade after sunset, with most areas remaining dry overnight. Clear spells will develop, especially across the northern half of the country. Patchy mist and fog will return in the early hours, especially where skies clear. The southwest may still see one or two lingering showers. Temperatures will dip to between 5 and 10 degrees, coolest in clearer inland areas with very light northerly breezes.
What To Watch For
- Thunderstorm risk is highest in the southern half of Ireland between 2pm and 7pm
- Spot flooding is possible where heavy downpours occur in a short timeframe
- Mist and fog may linger along the coast well into the afternoon
