Last month was the fourth warmest June on record, according to Met Éireann.

The highest temperature recorded was 29.6C in Mount Dillon, Co Roscommon on June 20th, which is also the warmest temperature this year.

Mean temperatures for the month ranged from 13.7 °C (1.2 °C above its LTA) at Knock Airport, Co Mayo to 15.6 °C (1.7 °C above its LTA) at Phoenix Park, Co Dublin.

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.

All of the warmest June temperatures have been recorded in the last 20 years, with the other warmest June's in 2023, 2018, 2010 and 2006, with 2023 the warmest in history.

The average temperature last month was 15.10 °C.

It was also the wettest June since 2022, and the 24th wettest since 1941.

Percentage of monthly rainfall values ranged from 56 per cent, the month’s lowest monthly rainfall total of 47.0 mm, at Cork Airport, Co Cork to 206 per cent, the month’s highest monthly rainfall total of 165.0 mm, at Athenry, Co Galway.

The highest daily rainfall total was 42.6 mm at Casement Aerodrome, Co Dublin on Saturday June 14th.

The number of rain days* 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.
