BREAKING: Met Office declares hottest day of 2025 as temperatures soar to 33C in UK heatwave

Britain has experienced the hottest day of the year so far, the Met Office has said.

A provisional temperature of 33.2C was recorded at Charlwood in Surrey this afternoon, the national forecaster announced. It breaks the previous record for 2025 set earlier this week. Forecasts show that conditions could peak at 34C in the southeast today, though thunderstorms are expected further north. An amber heat-health alert issued by the UK Health Security Agency remains in force across England until Monday, with the NHS and wider healthcare sector warned to expect an increase in heat-related hospital admissions, particularly among vulnerable groups.

Deputy Chief Meteorologist, Dan Holley, said: “The highest temperatures from this hot spell are forecast for Saturday, with low 30s Celsius fairly widely across England, and up to 34°C possible in eastern areas. Despite this, the more uncomfortable heat will be in northern and western areas initially, where despite somewhat lower temperatures the air will be more humid.

“While Saturday will be a dry and fine day for many, a few showers or thunderstorms will be possible across northern and western parts of the UK, with an increasing risk of some intense thunderstorms developing across portions of north Wales, northern England and southern Scotland later in the afternoon and into the evening hours, which could bring heavy downpours, frequent lightning, gusty winds and possibly large hail."
