The UK could have its hottest day on record this week, with temperatures forecast to hit up to 41C (106F).

The Met Office has issued a red extreme heat warning on Monday and Tuesday in much of England, from London and the south-east up to York and Manchester.

The current highest temperature in the UK is 38.7C, in Cambridge in 2019.

High temperatures are also forecast across the UK – with amber warnings in the rest of England, all of Wales, and parts of Scotland.

London is set to be one of the hottest places in the world on Monday, with temperatures soaring above the Western Sahara and the Caribbean.

The hot weather will continue on Tuesday – with overnight temperatures warned to be in the mid twenties – before cooling on Wednesday.

It is the first time the Met Office has issued a red warning since the system was introduced last year.

It means “widespread impacts on people and infrastructure” are expected, with “substantial changes in working practices and daily routines” required.

Some schools plan to close early – or not open at all – although the government has issued guidance designed to keep them open.

Network Rail said people should travel only “if absolutely necessary” on Monday and Tuesday, with some cancellations already announced, and speed restrictions in place across the network.

LNER will not run services between London and Leeds and York for much of Tuesday.

Jake Kelly from Network Rail explained precautions are being taken to mitigate the impact of the extreme temperatures, but the heat would place railway infrastructure under “exceptional stress”.

Responding to claims the UK has seen worse heat – such as during the prolonged heatwave in 1976 – BBC Weather’s Simon King said the expected temperatures are much hotter, up to 10C above the extended heatwave and severe drought experienced then.

“That is where you the real health impacts come into play because these are dangerously high temperatures.”

Alongside the Met Office’s red and amber warnings, the UK Health Security Agency has issued a level four warning for England, which the government is treating as a “national emergency”.

After an emergency Cobra meeting for ministers on Saturday, Health Secretary Steve Barclay said ambulance capacity would increase, alongside more call handlers.

The London Ambulance Service said it had seen 7,000 calls a day with rising temperatures and expected up to 8,000 on both Monday and Tuesday. A busy day in the capital would generally see around 5,500 calls, it explained.

While there is no warning in place for Northern Ireland, temperatures are predicted to reach 30C on Monday.
