Met Office - Summer 2025 Was UK's Hottest Summer On Record; All Top 5 Hottest Summers Have Been Since 2020

The UK has had its hottest summer on record, the Met Office has said, after the country faced four heatwaves in a single season. The mean temperature for meteorological summer, which encompasses the months of June, July and August, was 16.1C (60.98F), which is significantly above the current record of 15.76C set in 2018.

All five of the hottest summers on record have now occurred since 2000 – a clear signal of the global heating that scientists say is resulting from increasing concentrations of greenhouse gases in the atmosphere.

The Met Office said it had conducted a rapid analysis that found the record-breaking summer temperatures had been made about 70 times more likely because of human-induced climate change.

Dr Mark McCarthy, the agency’s head of climate attribution, said: “In a natural climate, we could expect to see a summer like 2025 with an approximate return period of around 340 years, while in the current climate we could expect to see these sorts of summers roughly one in every five years.
