Last month was fourth-warmest August on record

August 2025 was the fourth-warmest August since records began and the ninth-warmest of any across 126 years of the country’s meteorological records.

That is according to Met Éireann’s provisional weather statement for last month, based off the 25 principal weather stations operated by the national forecaster.

Last month’s data show an average temperature of 16.83°C, which is 2.15°C above the 1961-1990 long-term average for the month of August and just over 1.5°C higher than the 30-year average up to 2020.

The last warmest August fell in 1995 when average temperatures hit 17.75°C.

The provisional weather statement confirmed that rainfall was also below average last month, as just three-quarters of the average long-term rainfall fell.

“August 2025 was very warm, with temperatures well above average at all stations,” Met Éireann stated on releasing the data.

“It was wet in parts of the west, but dry elsewhere, especially in the east and south as high pressure dominated through most of the month.”

The forecaster reported that heat from central and western Europe pushed across Ireland in the second week of August, leading to several weather stations experiencing temperature highs of up to 28°C on the 12th of the month.

Met Éireann's provisional data for the month of August also confirmed the tale of two halves on rainfall.

Moorepark in Co Cork received just 30.5mm or 37% of the area’s long-term average, while Athenry, Co Galway, witnessed two-fifths more rain than its average.

While Phoenix Park’s weather station showed that fell just nine days over the month, Newport, Co Mayo, recorded 21 rain days in August.
