As Paris endures an unprecedented heatwave, with temperatures exceeding 40 degrees Celsius and a red alert in effect, the city's canals have become an unofficial refuge for residents seeking relief. However, British water safety campaigners have issued urgent warnings against swimming in these urban waterways, citing hidden dangers and a lack of oversight.
The phenomenon of canal cooling is not new, but the scale of this week's heatwave has drawn thousands to the banks of the Bassin de la Villette and the Canal Saint-Martin. Authorities have installed temporary pools and misting stations, but many have bypassed these measures in favour of the canals themselves.
The UK's Royal Life Saving Society and the Canal & River Trust have released a joint statement cautioning against such behaviour. 'Canals are not swimming pools,' the statement reads. 'They contain submerged hazards, variable depths, and hidden currents. The water quality is not monitored for bathing, and there is a risk of disease.'
The Parisian authorities have not banned swimming in the canals, but they have discouraged it. The city's police prefecture has deployed additional patrols to remind citizens of the dangers. Yet the allure of the cool water is proving difficult to counter.
This comes as France faces its third heatwave of the summer, with the health ministry reporting a rise in heat-related emergencies. The red alert, the highest level, indicates a danger to life even for healthy individuals. Paris has opened cooling centres and extended park hours, but the canals remain a popular if risky alternative.
For British tourists, the advice is clear: avoid the canals. The UK Foreign Office has updated its travel advice for France, warning that swimming in unsupervised areas increases the risk of accidents. The statement urges visitors to use official swimming facilities.
The situation highlights a broader issue of urban infrastructure ill-prepared for extreme heat. As climate change intensifies, cities like Paris will need to consider how to provide safe, accessible cooling options. For now, the canals serve as a reminder that in a heatwave, even the most picturesque solutions come with hidden costs.
