Met Éireann’s climate statement for Spring 2026 shows that the last three months were the third-warmest on record in Ireland since 1900.
Climatologist Paul Moore said the mean temperature was 10.14 degrees.
Speaking on RTÉ’s Drivetime, he said that seven of the top ten warmest springs in Ireland since 1900 have been since 2001.
“There’s definitely a climate change increase there, we’ve seen a clear trend of the springs getting warmer, and indeed every month and every season is trending upwards.”
He said that rainfall was “about average, about 103% for the whole of Spring,” but that was “very divided” between east and west, drier in the east and “much wetter” in the west.

Mr Moore said that May 2026 was Ireland’s seventh-warmest May on record, April was the 12th-warmest April on record, and March was the 16th-warmest March on record.
The final third of May “really pushed the temperatures up,” he added, after a “relatively cool” first two-thirds of the month.

“The national maximum May [temperature] record was beaten by over 2.5 degrees in a couple of the [weather] stations, so that’s a phenomenal jump in any one national maximum temperature record for any month.
“It just shows you that, in extreme situations, where we get high pressure and heat coming up from the south, we can now reach levels that we wouldn’t have been able to reach before,” Mr Moore said.
