An amber heat health alert has been put in place across the whole of England with temperatures set to reach more than 30C today.

From midday, the UK Health Security Agency (UKHSA) has placed the warning over all regions of the country - which will last until 9am on Monday.

Britons are warned that "a rise in deaths" is likely among those with pre-existing health conditions, as well as those aged over 65.

Across the south of England, temperatures are expected to soar to as high as 32C by Thursday afternoon, with temperatures above 20C across almost all of the UK.

The extraordinary heat would make today the hottest day of 2025 so far, beating 29.4C heat recorded in Suffolk last Friday.

On Friday, the Met Office says conditions will turn "very warm, dry and sunny once again".

Forecasters continue: "Isolated showers are possible across northern Scotland and southwest England, while isolated thunder possible in the southwest. Breezy along southern and eastern coasts."
