The weather is expected to take a turn for the worse following a surprising rise in temperatures over the past week. Wetter and colder weather, including possible thunderstorms, are expected to replace the mini heatwave.

The Met Office says the UK could see temperatures peak over the weekend, with some parts of the country set to experience the hottest day of the year so far. Parts of south-east England are expected to reach a maximum of 26C on Saturday, beating the current record this year of 23.4C in Santon Downham in Suffolk, with temperatures across the country substantially warmer than their seasonal averages.

London is forecast to hit 23C to 24C daily peaks for the rest of the week, with slightly cooler temperatures of about 20C across parts of western England and Wales. The forecaster said Thursday and Friday will be sunny and dry in most of the UK, with scattered showers across northern areas and heavier rainfall in northern parts of Scotland, which is expected to move away from Thursday.

But next week will bring unsettled weather, the Met Office said, as temperatures cool and an area of low pressure from the Atlantic brings scattered showers and possible thunderstorms as early as Sunday afternoon.

Amy Bokota, senior operational meteorologist at the Met Office, said: “It’s already been quite warm but as we head later on through the week, I’m expecting it to slowly climb day on day. For the UK as a whole, for the early part of May, the average daytime temperature is around 16C, so it’s quite a bit above average.”

“We’ll likely see temperatures back into the high teens, perhaps low twenties in a few spots, but certainly a few degrees less,” Ms Bokota said.

The Met Office said the sunny weather will bring “moderate to high” UV levels which could cause sunburn even where it is cloudy, and recommended people use sunscreen and wear suitable clothing, including hats and sunglasses.
