Glastonbury revellers should ready themselves for a sizzling weekend, as temperatures could hit record-breaking highs of over 35C, according to forecasters.

The Somerset music festival, which has been known in the past for seeing torrential downpours, will enjoy temperatures well over 30C from Friday, as south-west England gets as hot as parts of north Africa.

Things won’t cool down as the weekend progresses, forecasters have warned, with record-breaking heat sweeping the whole of southern England on Saturday.

“The UK’s highest temperature on record was 35.6C, in 1976 in Southampton. It’s possible we could see that beaten this weekend,” Met Office meteorologist Bonnie Diamond told the Standard.

Ms Diamond warned things might feel unpleasantly hot at the UK’s biggest festival, as the weather “won’t be bright and sunny, but very hot and humid”.

With temperatures hitting up to 32C on Friday, and up to 35C on Saturday, she advised the Worthy Farm festival-goers to “drink plenty of water to avoid dehydration”.

“The sunshine will be hazy, but cloud doesn’t mean people won’t burn – UV levels will be high, so people should take precautions,” she advised.

Tent-dwellers are further warned that conditions will remain hot and sticky overnight, with temperatures in the high-teens or low twenties predicted in south-western parts of the UK.

The predicted spike in temperatures, and the health risks these could pose, follow warnings of a different nature.

Three separate storm and rain alerts will be in place in England, Scotland, Wales and Northern Ireland between Monday and Tuesday, with up to 80mm of rain possible in some parts.

The Met Office has issued yellow thunderstorm warnings across most parts of England, with flash flooding and hail possible overnight tonight.

“We could see up to 60mm of rain across south-east England on Monday, with parts of Wales and north-west England also vulnerable to the risk of localised flooding,” said Ms Diamond.

Heavy rainfall is also expected for Scotland, where the Met Office has told residents to prepare for possible power cuts and travel disruption.

The official weather warnings are set to expire at 10am on Tuesday, when the heatwave will gradually take over.

Wales, south-west and central England will bear the brunt of the heat from Wednesday to Friday, with isolated temperatures hitting highs of around 30C on all three days.

But by the weekend, cooler North Sea breezes will be replaced by warm southerly winds across eastern and southern England, meaning blistering temperatures for all.

Temperatures in France could hit over 40C, it also emerged today. France, Germany, Switzerland and Belgium could all see national records for June broken in the coming days.

The heat is being caused by a weather system over the Atlantic which is creating high atmospheric pressure over the region, drawing up hot air from northern Africa and Spain
