Met Office issues first red warning for heat

The UK’s national weather service, the Met Office, has issued its first red warning for exceptional heat. It is expected to reach 38-40°c (100-104°F) in London on Monday and Tuesday of next week. To date, the highest temperature ever recorded in the UK was 38.7°c in Cambridge in 2019. The London record is 38.1°c, recorded at Heathrow in 2003.

A red warning means dangerous weather conditions are expected, and you should take steps to keep yourself and others safe.

On Friday morning, the Met Office’s chief meteorologist, Paul Gundersen, said:

Exceptional, perhaps record-breaking temperatures are likely early next week to spread quite a bit across the red warning area on Monday and center a little further east and north on Tuesday. There is currently a 50% chance that we could see temperatures above 40°C and an 80% chance that a new maximum temperature will be reached.

At the time of writing (Friday afternoon), an amber heat warning has been issued in London for Sunday, meaning a serious disruption as a result of the weather is likely, with red heat warnings in effect for Monday 18 and Tuesday 19 July.
