Parts of UK already in heatwave as hottest day of year could be on way

Parts of the UK have hit heatwave criteria for the first time since June as temperatures rise and the hottest day of the year is expected this week.

And while the hottest temperature recorded on Tuesday was 30.7C and did not pass June’s top reading of 32.2C, a new record is likely on Wednesday or Thursday, the forecaster added.

Amy Bokota, meteorologist for the Met Office, said: “In total there’s 13 stations that have officially marked it [heatwave]. As you go through the next couple of days quite a few extra will be added onto that.

“It will then be 32C right the way until Sunday for some places in the south.”

The UK Health Security Agency upgraded its heat alert to amber due to the hot temperatures.

The warning covers every region of England apart from the North East, where a yellow alert is in place.

Temperatures are also set to reach 27C in Northern Ireland and Scotland, the Met Office said.

The temperatures could start to drop gradually at the weekend and there is a chance of thunderstorms breaking out from the north and west of the country, the forecaster added.
