Switzerland shatters 80‑year June heat record as UK sees new temperature highs

Switzerland recorded its hottest June day ever on June 25, with temperatures reaching 38 °C in Basel and across six northern stations, breaking the 1947 record of 36.9 °C. MétéoSuisse reported the first June observation above 37 °C and placed half the country under level‑4 heat‑risk alerts, forecasting the heatwave to ease by early next week.

In the United Kingdom, the Met Office issued red heat warnings for large parts of southern England, anticipating temperatures near 40 °C. A new June record of 36.1 °C was logged at the Gower coast, while Charlton saw 35.7 °C. The extreme heat prompted school closures, rail cancellations, and public health warnings, with officials urging people to limit travel and stay hydrated.
