Britain will bask in “wall-to-wall sunshine” on the weekend amid a heatwave that could bring record-breaking temperatures upwards of 32C, forecasters have said.

Sunseekers in London and the south-east of England can expect highs of 29C and clear skies on Sunday after Friday saw parts of the country hotter than Los Angeles and Santorini.

It is expected that the heatwave will continue into next week, with it set to go above a scorching 32C potentially making it the warmest day of the year so far.

This year’s record high currently stands at 32.7C, recorded at Heathrow on June 17, the Met Office said.

It comes after temperatures soared across the country on Friday, with the mercury hitting 28.5C in St James’s Park, London.

A heat-health alert has been issued for some regions, with those in affected areas advised to shade or cover windows, check fridges are working properly, and that medicine is correctly stored.

The UK Health Security Agency (UKHSA) warning will be in force from Monday July 11 until Friday July 15, including regions in the south and east of the country.

Met Office meteorologist Dan Stroud said a brief spell of light cloud on Saturday across most parts of the UK would break up over the course of the weekend.

The forecaster added: “During the course of the overnight period and into Sunday we’re likely to see cloud breaking up readily across England tomorrow, with temperatures up a notch on what we will see over the course of Saturday.

“There’s a headline maximum of around 29C over the course of Sunday in London and the South East.

“We should see pretty much wall-to-wall sunshine across the bulk of England and Wales and a good portion of Scotland. A lot of clear sky tomorrow for many of us.”
