The heat is expected to continue into the first half of next week, getting hotter and hotter with the potential to reach the maximum temperature of the year.
With temperatures hitting 33.2C (91.8F) on June 21, Charlwood, Surrey, saw the hottest day of 2025 to date.
Climate change is making heatwaves more frequent and increasing the likelihood of experiencing excessive heat.
The heat will have an impact on a number of summer events. With temperatures above the 2001 record of 29.3C (recorded at Kew), it is probably going to be the hottest start to Wimbledon. Temperatures will approach the 2017 Glastonbury record of 31.2C, which was observed at Rodney Stoke.
