June 2025 has become the fourth warmest June on record for Ireland, Met Éireann said in its climate statement for the month, issued on Wednesday, July 2.

All stations recorded mean temperatures above their Long Term Average (1991-2020 LTA), the Irish national meteorological service said in its statement.

On Friday, June 20, Mount Dillon in Co Roscommon recorded 29.6°C (85.28°F), the maximum temperature of the year in Ireland so far.

Overall, June 2025 was notably warmer than average, continuing the recent warmer-than-normal monthly trend, Met Éireann said.

It was the fourth consecutive month with temperatures in the respective top eight averages on record in 126 years of records.

The average temperature for June 2025 (using the Island of Ireland dataset*) was 15.10 °C, making it the fourth warmest June on record since 1900.

Of the top ten warmest Junes, five have occurred recently (2023, 2018, 2025, 2010, and 2006).

Ireland's warmest June was in 2023 with an average temperature of 16.22°C, and the coldest June was in 1972 with an average temperature of 12.68°C.

Malin Head in Co Donegal had its highest maximum temperature for June since 1957 with 25.5°C recorded on Friday, June 20.

Two stations - Phoenix Park, Co Dublin (19.0°C) and Oak Park, Co Carlow (with 18.1 °C) - reported record high all-calendar-month minimum temperatures on Saturday, June 28.

On the same day, Dublin Airport (18.4°C), Casement Aerodrome, Co Dublin (18.0°C), Dunsany, Co Meath (17.2°C), and Johnstown Castle, Co Wexford (16.0°C) reported record high minimum temperatures for June.

Met Éireann shared these other key findings from its June 2025 Climate Statement:

The average temperature for June 2025 was 1.88°C above the 1961-1991 long-term average for the month and 1.42°C above the long-term average for the most recent climatological reference period of 1991-2020.

Provisional gridded rainfall data suggests June 2025 averaged around 100 mm, which is 117% of the month’s long-term average from 1991-2020.

2025 ranks as the 24th wettest June in records since 1941 and the wettest June since 2022.
