UK weather forecast latest: London set to be hotter than Portugal this weekend with highs of 21C

London is set to be hotter than Portugal this weekend but sun worshippers should also braced for thunderstorms.

Temperatures will soar as high as 21C in the capital on Saturday with the sunniest spots likely to be St James’s Park and Kew Gardens, Met Office meteorologist Sarah Kent said.

The mercury will hit highs above those expected on Portugal’s south coast where it is expected to be around 17C.

But Ms Kent told the Standard that if temperatures do hit the highest predicted figures those enjoying the warmer temperatures should also pack an umbrella.

The Met Office said the rest of the UK will be “generally warmer over the weekend with sunshine and scattered heavy showers.”

She said: “It is going to be hotter than it has been at the weekend but as the temperatures rise we see an increase of home-grown showers caused by the sunshine.

“We also see a risk of thunder storms as it gets warmer.”

Temperatures are likely to stay around 20C on Sunday with more sunshine expected, the meteorologist added.

A risk of showers remains but downpours are expected to be lighter than on Saturday.

The warm weekend follows a “drizzly” and “grey” end to the week with temperatures reaching highs of 17C on Thursday and Friday.

Heavy downpours are expected around 4pm on Thursday afternoon and may set in overnight.

The rest of the UK is set to see warm weather develop, Ms Kent added but it will remain cooler in Scotland and the north than in the south.

Maximum temperatures are expected to reach the low teens, she said.
