UK weather forecast: Brits brace for 91F blast as heatwave hits on weekend

Met Office chief meteorologist Matthew Lehnert said: “Official heatwave criteria could be met for parts of southern and eastern England by the end of the weekend.

“It’s worth noting the temperatures in the south will remain quite high overnight this weekend, so it’s important to look out for those who may be more vulnerable to heat.”

The UK Health Security Agency issued a heat health alert in anticipation of mercury soaring.

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said: “This heat health alert means that in the coming days we are likely to experience another period of hot weather, so it’s important that everyone takes sensible precautions while enjoying the sun.

“Forecast temperatures this week could primarily impact those over the age of 65 or those with pre-existing health conditions. If you have friends, family or neighbours who are more vulnerable, it is important to check in on them and ensure they are aware of the forecasts and are following the necessary advice.”

The UK’s national weather agency forecast temperatures to reach 29C in London on Sunday.

Brian Gaze, founder of The Weather Outlook, also told The Daily Express: "The main focus will be Sunday. In the southeast and East Anglia, temperatures may reach a scorching 33C (91F)."

The Met Office’s forecast for Saturday said: “Outbreaks of rain continuing northeastwards across Northern Ireland and Scotland with some thundery showers.

“Dry with hazy sunny spells across England and Wales. Very warm especially in the southeast.”

Looking ahead to Sunday until Tuesday, the UK’s national weather service added: “Remaining hot across the southeast on Sunday but rain, locally heavy and thundery, will bring fresher conditions to the west.

“Changeable and cooler for all early next week.”
