People can expect blue skies, sunshine and the hottest day of the year so far during the bank holiday weekend, according to the Met Office forecast.
Temperatures are expected to reach 23C in London on Saturday and 24C in Manchester and Liverpool on Sunday.
While on Monday, the mercury is set to reach 25C, meaning it would surpass the current high for 2021, which was 24.5C (76.1F) recorded in Kew Gardens on March 31.
Met Office forecaster Alex Deakin said: "Sunglasses, sunhat and sun screen definitely required this weekend. Finally, some warm sunshine on offer this May after what has been a very, very chilly month."
He added: "We will start the weekend with a lot of cloud and for some it will be a bit damp and dreary, initially, certainly over the Midlands, parts of Wales and the west coast of Scotland, but that rain should be fizzling out through the morning.
"Most places will steadily brighten up but it could take a while. Some places will be cloudy into the afternoon, but generally it is turning sunnier as the day goes on."
The Met Office's provisional stats show the UK has already had its fourth wettest May on record with an average of 199mm falling.
The wettest locations, receiving more than twice the average rainfall, were the south west and north east of England, as well as Wales and parts of eastern Scotland.
Parts of Scotland and northern England even saw snow at the beginning of the month when temperatures of -5.5C were recorded.
According to the Met Office, the often dull and wet conditions resulted in subdued temperatures across the board.
Forecaster Matthew Box said: "Given that we have had a reasonably cold and then a wet couple of months through spring, with April being cold and May being wet and cloudy and generally on the cool side too, we've got a sunny end to May.
"It might catch a few people out given that we haven't seen much sun and UV levels are going to be quite high over the weekend as well so that's something to be aware of."
