Historic Heatwave Breaks Records as Ireland Seals Its Warmest Summer in 127 Years

DUBLIN — Met Éireann has confirmed that Ireland has officially endured its hottest summer since records began 127 years ago, breaking temperature benchmarks for the second consecutive year.

Following an exhaustive analysis of meteorological data across the country, the national weather service reported that the national average temperature for June, July, and August reached 16.28°C. This surpasses the previous record set just last year in 2025 by 0.09°C, soaring roughly 2.03°C above the long-term climatological average.

High-pressure dominance and a northern-displaced jet stream across western Europe fueled the exceptional conditions, driving extended dry spells and unprecedented heat. A staggering fourteen reporting stations—including all primary monitoring sites across Dublin and Cork—logged their hottest summers on record. The season's peak temperature hit a scorching 32.2°C at Athenry, Co Galway.

While the exceptional sunshine brought a celebratory mood to coasts and cities alike—aligning with a tourism and hospitality boom that recently saw County Mayo's Ashford Castle crowned the world's most beautiful hotel—climatologists emphasize that the relentless run of record-breaking seasons underscores an intensifying long-term warming trend across northern Europe.
