The Met Office has confirmed that summer 2026 was the hottest on record in the UK, with a mean temperature of 16.5C. This unprecedented heat was made 130 times more likely due to human-induced climate change, according to provisional data.146

In England, temperatures peaked at 38.1C (100.1F) at Kew Gardens in London on 13 August, while the country also experienced its driest July on record, with only 6.5mm of rainfall, significantly below the long-term average.27

Dr. Mark McCarthy, head of climate attribution at the Met Office, stated, “The summer of 2026 has been remarkable and is an example of the extremes we can expect to see more frequently as a consequence of human-induced climate change.”

Dr. James Pope, a climate scientist, noted that this summer aligns with projections for 3C of global warming, indicating that summers will become both hotter and drier in the future.8

Dr. Amy Doherty, leading the National Climate Information Centre, emphasized that the conditions this summer have broken UK climate records with increasing frequency, reflecting the ongoing impact of climate change. Notably, the previous summer mean temperature record of 16.1C set last year has been surpassed, pushing the infamous summer of 1976 down to seventh place for average summer mean temperature, with the top five warmest summers all occurring since 2003.9
