The Met Office said the UK provisionally set a new June daily maximum temperature record on 24 June, with 36.1C reported at Gosport, Hampshire. That figure, if verified, would exceed the previous 35.6C June record reached in 1976 and 1957. The agency said the equipment and site would still need formal checks before any value entered the official record.
The number matters less as a trophy than as a warning about design limits. The Met Office said other stations also beat the previous record, Wales provisionally broke its June highest minimum temperature, and a red extreme heat warning had been issued. Al Jazeera reported that the UK heatwave had already put preparedness under scrutiny, while the Guardian tracked wider European disruption including warnings, event cancellations and pressure on services.
World Weather Attribution, a research consortium that conducts rapid climate-attribution studies, put the episode in a longer frame on Friday. Its analysis said the heat over western Europe was the most severe ever recorded for the region studied, focused on the three hottest days and nights. It said temperatures like those seen in June 2026 would have been virtually impossible in June under 1976 climate conditions and that a similar June heatwave would have been about 3.5C cooler during the day in 1976.
The study also looked beyond ordinary air temperature to wet-bulb globe temperature, a heat-stress measure that combines temperature and humidity. WWA said about 45% of European urban regions in its sample were breaking or forecast to break indoor heat-stress thresholds during the 18-29 June period. That is why the event belongs in the environment and public-health file at the same time: humidity and nighttime heat reduce the body's ability to recover, especially in homes not designed for sustained heat.
