Summer of 2026 was UK’s hottest on record, Met Office says

Meteorologists say average mean temperature of 16.5C was made 130 times more likely by climate crisis

This year’s summer was the UK’s hottest on record, according to provisional data, and the Met Office said the season’s mean temperature was made 130 times more likely by the climate crisis.

Record-breaking and back-to-back heatwaves have scorched much of Europe. In England, temperatures peaked at 38.1C (100.1F) at Kew Gardens in London on 13 August, and June had already been confirmed as the country’s hottest since records began in 1884. Scientists have said these heatwaves are only possible because of the climate crisis driven by burning fossil fuels.
