As the UK experiences one of the warmest summers on record, those living on canal boats are facing extreme heat. According to the Canal & River Trust, there are around 35,000 boats on England and Wales' waterways, and many residents report that their narrowboats become unbearable during heatwaves.
Boat dwellers describe the conditions as 'like an oven', with temperatures inside the metal hulls often exceeding 40°C (104°F) during the day. The lack of insulation and the confined space mean that even with windows open, the heat is difficult to escape.
The Canal & River Trust advises boaters to use awnings, reflective paint, and ventilation to mitigate the heat, but many residents say these measures are insufficient during prolonged hot spells. Some have resorted to sleeping on the roof or in nearby parks to find relief.
Health experts warn that extreme heat can be dangerous, especially for the elderly and those with pre-existing conditions. They recommend staying hydrated, avoiding strenuous activity during peak hours, and seeking cooler environments when possible.
