The United Kingdom is poised to experience a significant heatwave, with temperatures potentially reaching 38C (100.4F) under an amber extreme heat warning. This surge in heat is expected to break numerous temperature records, adding to a list of already established highs for the year.
If temperatures reach 35C (95F) this week, it will mark the fourth calendar month in the current year to record temperatures at or above this threshold, a situation described as unprecedented. Should temperatures climb to 36C (96.8F) or higher, the current year would become the first on record to register four separate days at or above that mark. This would surpass the previous record of three days, a distinction currently shared by the years 1990, 2003, 2020, and 2026.
Specific locations, including London, could see temperatures touch 38C. If this occurs, it would be the second time the UK has experienced such a high reading this summer, equalling the previous high recorded in Lingwood, Norfolk on June 26. This temperature would also tie for the hottest August day recorded since 2003, when a high of 38.5C (101.3F) was registered.
Forecasters indicate that heat will peak again on Thursday, with the amber warning signifying a high likelihood of prolonged periods of high temperatures. As long as average or above-average temperatures persist throughout August, the current summer is set to be the warmest on record, surpassing the previous warmest summer in 2025.
The prolonged dry and hot conditions have already had a visible impact.
