The UK's recent record-breaking heatwaves have left many wondering why the temperatures feel more unbearable than in hotter countries. June saw the hottest day on record in Santon Downham, Suffolk, at 37.3°C, following three consecutive warmest days under a rare extreme heat warning. Disruptions included school closures, train cancellations, and homes becoming heat traps during tropical nights.
Met Office spokesperson Stephen Dixon explained that the UK's air tends to be more humid than in continental Europe, making it harder for sweat to evaporate and cool the body. Additionally, UK homes are built to retain heat during cold winters, unlike European homes designed to stay cool in summer. This insulation traps heat, exacerbating discomfort.
Attitudes also play a role. When abroad, Britons expect heat and adapt their routines, but at home, the sudden heat catches them off guard. One social media user noted that even after living in the US with regular 35°C temperatures, the UK's heat felt worse due to humidity and lack of preparation.
The extreme heat forced cancellations, including a talk on extreme heat during London Climate Action Week, and closures of landmarks like Tower Bridge and Cutty Sark. London pavements and station platforms reached nearly 60°C. Greenpeace called it a 'public health emergency' driven by fossil fuels, urging the government to improve cooling in homes and schools, and increase green spaces.
Access to green spaces remains unequal, with only 26% of people in deprived areas having access, compared to 38% in affluent areas. London's mayor admitted the city is unprepared and unveiled a heat plan inspired by Phoenix, Arizona, as such conditions become more common.
