Ireland could experience record-breaking temperatures this week as a prolonged spell of hot weather continues across the country. Forecasts from Met Eireann indicate that some areas may reach 28 degrees Celsius, with Munster and Leinster expected to be the warmest regions.
Potential New Records
The current highest May temperature on record in Ireland stands at 28.4 degrees Celsius, recorded on May 31, 1997, at Ardfert Liscahane in County Kerry. The approaching heatwave could challenge or even surpass this mark, as the national meteorological service predicts long spells of sunshine nationwide.
Daily Forecast
On Monday, temperatures are expected to range between 23C and 28C, with the highest values in the south and east. The warm weather is set to persist, with similar highs of up to 28C forecast for Tuesday and 27C on Wednesday.
UK Also Sizzles
Across the Irish Sea, the United Kingdom is bracing for what is predicted to be the hottest bank holiday on record. Forecasters anticipate temperatures of 34C in Greater London and south-east England on Monday. This follows the UK's hottest May day in at least 79 years on Sunday, when a high of 32.3C was recorded at Kew Gardens in south-west London.
Northern Ireland has already set a new record for 2026, reaching 23.4C in Armagh on Sunday. Temperatures could climb to 24C there on Monday, continuing the trend of unseasonably warm weather.
Residents across Ireland and the UK are advised to stay hydrated, seek shade during peak hours, and take precautions against the heat as the exceptional weather continues.
