recorded in the UK was 38.5°C, at Faversham on 10 August 2003. Using the average daily maximum temperature it is the second hottest July on record for England, with only 2006’s average daily maximum temperature of 25.2°C being higher than the current provisional figure of 24.8°C. Wales’s figure stands

. This time though, the heat was more concentrated on the very far south and east of England.    This map shows the places to reach heatwave criteria from 27-30 June 2025. Met Office Climate Scientist, Dr Amy Doherty, said: "While we’ve not conducted formal climate attribution studies into June 2025’s
