The heatwave will pose a ‘danger to life’ in Bracknell as it becomes subject to the UK’s first ever ‘red alert’ temperature warning.

The Met Office has forecast highs of 40C in the country for the first time, with at least 35C predicted for the town on Tuesday.

All residents are vulnerable to serious illness and a danger to life from the heat, not just the elderly or young children, the forecaster said.

Met Office Chief Meteorologist Paul Gundersen said “Exceptional, perhaps record-breaking temperatures are likely early next week, quite widely across the red warning area on Monday, and focussed a little more east and north on Tuesday.

“Currently there is a 50 per cent chance we could see temperatures top 40C and 80 per cent we will see a new maximum temperature reached.”

The current record high temperature in the UK is 38.7C, which was reached at Cambridge Botanic Garden on July 25 in 2019.

“Nights are also likely to be exceptionally warm, especially in urban areas. This is likely to lead to widespread impacts on people and infrastructure.

“Therefore, it is important people plan for the heat and consider changing their routines. This level of heat can have adverse health effects.”
