According to the Met Office, London and parts of East Anglia are expected to reach 27°C on Friday, May 1, 2026, making it hotter than parts of Hawaii, which typically see temperatures around 25°C at this time of year. The warm weather is due to a high-pressure system bringing clear skies and southerly winds.
This temperature is well above the May average for the UK, which is around 15-18°C. The Met Office has issued no heat health warnings, but advises staying hydrated and using sunscreen during peak hours.
Similar conditions are expected across southern England, with temperatures in the mid-20s Celsius. The warm spell is forecast to continue into the weekend, though cooler conditions may arrive by Monday.
