June 2025 was the fourth-hottest June recorded in the last 126 years, according to Met Éireann.
The national forecaster released its climate statement for June 2025, which showed that last month was the fourth consecutive month with temperatures in the respective top 10 averages on record.
The average temperature for June was 15.1°C, which was 1.42°C above the long-term average.
Of the top 10 warmest Junes, five have occurred in the last 20 years, with the warmest month occurring in 2023.
The month’s highest temperature was reported at Mount Dillon, Co Roscommon, on Friday 20, with a temperature of 29.6°C.
Meanwhile, the lowest temperature of 3.5°C was reported at both Mount Dillon, Co Roscommon, on Monday 2 and Mullingar, Co Westmeath, on Sunday 8.
A spokesperson for Met Éireann said: “The final third of the month has been remarkably hot for Europe, when an intense area of high pressure built over mainland Europe, provoking heatwave conditions to develop over it.
“While this happened over mainland Europe, Ireland stayed on the cloudier northern edge of the heat dome, which brought some uncomfortably high nighttime temperatures, contributing to the high June temperatures overall.”
Rainfall
Met Éireann reported that there was above-average rainfall last month overall. Generally, weather stations in Leinster, Ulster and Connacht saw above-average rainfall, while several stations in Munster saw below-average rainfall.
The highest daily rainfall total was 42.6mm at Casement Aerodrome, Co Dublin, on Saturday 14.
Met Éireann's Climate Statement for June 2025 showed that despite a cool start, June has become the 4th warmest on record for Ireland, with all stations recording mean temperatures above their long-term average and Mount Dillon, Co Roscommon, recording the maximum temperature of the year so far of 29.6°C on Friday 20 June.
The number of rain days with 0.2mm or more of rainfall ranged from 19 days at both Dublin Airport and Casement Aerodrome, Co Dublin, to 26 days at both Athenry, Co Galway, and Claremorris, Co Mayo.
In addition, the number of very wet days with 10mm or more of rainfall ranged from one day at seven stations, including Oak Park, Co Carlow, to five days at Ballyhaise, Co Cavan, Finner, Co Donegal, and Claremorris, Co Mayo.
Sunshine and wind
The majority of weather stations recorded monthly sunshine totals below their long-term average.
Sunshine totals were lowest at Knock Airport, Co Mayo, with 92.6 hours over June. Meanwhile, the highest number of daily sunshine hours recorded this month was 15 hours at Johnstown Castle, Co Wexford, on Wednesday 18.
Monthly mean wind speeds ranged from 10.4km/h at Ballyhaise, Co Cavan, to 26.9km/h at Mace Head, Co Galway.
