Whilst the wording of the warning is a little ott IMO the heat down in the South West has been notable.
I was in North Somerset just 2 miles from the sea yesterday and the car was reading 32C whilst on the move. Incredible heat for the location.
The usual sea breeze just wasn’t present allowing temperatures to soar.
I drove down to Newquay in the evening and it was still 27C at 6.45pm when I arrived. Combined with the humidity. It really did feel like I on holiday somewhere tropical.
Back in North Somerset today and it’s going to be another hot one!
