New figures indicate that 2,877 deaths in Britain were linked to hot weather during May and June, pointing to a severe early-summer impact from high temperatures across the country.
The two-month total is reported to be almost twice as high as the full figure recorded for 2025. That comparison suggests this year's warm-weather death toll has risen much faster than it did over the whole of last year.
The data adds to concerns about the health effects of prolonged heat, especially during periods of unusually high temperatures. Even before the summer has fully progressed, the latest numbers show a much heavier burden linked to hot conditions.
With May and June alone already producing a far higher toll than last year's overall total, the latest Britain heatwave data highlights how dangerous extreme heat can become when temperatures climb sharply.
