Paris struggles with illegal Seine swimming amid heatwave, contrasting with Geneva's river culture

Paris is grappling with an unexpected challenge as soaring temperatures drive residents to seek relief in the Seine and Canal Saint-Martin, leading to a rise in unauthorized swimming. Images of people jumping into the water from bridges have circulated widely on social media, highlighting a newfound public interest in urban swimming following the city's efforts to clean its waterways for the 2024 Olympics.

However, this newfound freedom is being curtailed by police. Swimming is only permitted in specific, designated areas, and the official season has not yet begun. For Canal Saint-Martin, access was limited last year to two locations, open only on Wednesdays and Sundays during specific hours from early July to September.

In contrast, Geneva offers a more established and relaxed approach to river swimming. At La Jonction, locals and tourists alike gather on wooden pontoons or along the riverbanks, with some using paddleboards or inflatable rafts to drift downstream. Despite a sign prohibiting diving from the Pont Sous-Terre, some young people still leap into the turquoise waters, a ritual that has become a well-oiled tradition in this iconic spot. Here, people swim as soon as the river temperature becomes milder, with some braving the waters year-round.
