The hot weather is set to continue after the hottest weekend of the year.

The mercury will keep rising all this week and not cool down until the weekend.

Saturday was the hottest day of the year so far, with the mercury peaking at 30.2C in Teddington, south-west London, the Met Office said.

Temperatures hit 28C in Watford on Saturday.

Forecaster Charles Powell today would be the same.

He said there would be a lot of “dry, sunny, warm, humid weather with high UV, high pollen”.

The 'killer' heatwave has seen a level 3 amber Government heat health warning - just one tier below a level 4 'national emergency' - issued, with officials warning sunseekers to stay inside between 11am and 3pm next week.

Hospitals have been told to brace themselves for an increase in admissions due to sun stroke, while members of the public were asked to be vigilant with vulnerable and elderly friends and relatives. 

Spokesman Dr Thomas Waite said: “For some people, such as older people, those with underlying health conditions and those with young children, the summer heat can bring real health risks.

“That’s why we’re urging everyone to keep an eye on those you know who may be at risk this summer.”
