BRITS are set to bask in a 30C scorcher today after the hottest day of the year so far was recorded on Monday.
Sunseekers are being urgently warned to take care in the heat as much of the nation is expected to flock to beaches.
The Met Office said central London could see a peak of 30C with temperatures in the high 20s across in south-east England on Tuesday ahead of England's final group stage Euros game.
Further north, Manchester and Leeds could reach 26C while the West Midlands is predicted to hit around 28C.
Meanwhile, Scotland and Northern Ireland will be slightly cooler and could see some showers.
Met Office Meteorologist Oli Claydon said "it won't be sunshine for everyone" but will still be warm even where there is cloud cover during the week.

He added: "We might see the occasional shower in parts of Northern Ireland and Scotland, where there will be a little bit of cloud through (Tuesday).
"But otherwise clearer skies in the South East and that's where we're going to see the highest temperatures."
And as people flock to beaches the Royal National Lifeboat Institution (RNLI) urged people to stay safe in the water.
Sam Hughes at the RNLI said: "We are expecting the coast to be extremely busy with this burst of warm weather.

"We want everyone to enjoy being around the water but we also want to make sure people stay safe and know what to do in an emergency.
"Always visit a lifeguarded beach and swim between the red and yellow flags.
"If you get into trouble in the water, Float to Live: tilt your head back with ears submerged and try to relax and control your breathing.
"Use your hands to help you stay afloat and then, once you are through the initial shock, call for help or swim to safety if you can. In an emergency call 999 and ask for the coastguard."
It comes after the top temperature on Monday was recorded at 28.3C in Wisley, Surrey - making it the hottest day of the year so far, the forecaster said.
The capital reached highs of 27.4C at St James's Park, while temperatures rose to 26.9C in Aberdeenshire and 25C in Northern Ireland.
As the hot spell continues, a yellow weather warning has been issued for most of England.
The UK Health Security Agency (UKHSA) and Met Office have said the heat could pose a risk to vulnerable individuals.
OAPs and people with health conditions are most at risk, but young people could also suffer.
