August was the fourth warmest on record, with all parts of the country recording above-average temperatures, Met Éireann has said.
An average temperature of 16.83 degrees is only behind the 17.75 degrees recorded in 1995, the warmest August on record, as well as temperatures in 2003 and 2022.
It is the third successive summer month to have been among the warmest on record in Ireland. June was the fourth warmest on record, while July was the ninth.
When final figures are collated, the summer of 2025 is likely to be among the warmest since records began.
