Sweltering weather is set to sweep across the country early next week, bringing sticky conditions and high UV levels.
Britain could experience its hottest day so far this year as hot air from the continent warms up the country.
“The warmest day is looking to be Tuesday,” forecaster Emma Sharples explained.
She said it would be “close-run thing” whether Tuesday would be the hottest day so far this year.
Many parts of Scotland could also experience temperatures in the high twenties, the Met Office said.
Ms Sharples said: “By the time we get to Thursday we’ll be back into much fresher conditions again, temperatures down to around average in the high teens and low twenties with a typical mix of summer weather which we’re more used to in the UK.”
