Hottest day on record! Temperatures reach 39.1°C in Surrey
It's officially the hottest day ever recorded in the UK!
The Met Office says it's reached 39.1°C in Charlwood in Surrey, beating the previous national record of 38.7C seen in Cambridge in July 2019.
But the record is unlikely to hold for long, as the Met Office is forecasting temperatures to reach as high as 41C on Tuesday (19 July) in some parts of eastern England.
It's already been the warmest night ever recorded as temperatures remained at 26 degrees Celsius in Emley Moor in West Yorkshire.
Much of England and Wales are under a "red" extreme heat warning until the end of Tuesday, with the heat causing disruption on transport networks and the risk of serious health impacts.
