Paris Opens Canal Saint-Martin Swimming During Heatwaves, Limits Cars

Paris deputy mayor Emmanuel Grégoire authorised supervised swimming in a 100-metre section of the Canal Saint-Martin between 4 pm and 8 pm during heatwaves, with the bathing area operating from 5 July to 6 September 2026. The decision directly affects residents in the 10th arrondissement who seek relief from summer temperatures without leaving the neighbourhood.

The measure arrives as the city completes a broader transformation of the canal that began in February 2024. That project converts the waterway into a biodiversity corridor and series of cool islands, adding 3.4 kilometres of cycle paths and 10 400 square metres of pedestrian space. Works are scheduled to finish by the end of 2026, coinciding with the first full season of the new bathing rules.

Vehicle restrictions and basin closures reshape daily movement

From 2026, private cars will be barred from the Quai de Valmy and Quai de Jemmapes except for emergency vehicles and local residents. The change reserves the quays for pedestrians and cyclists, altering routes for deliveries and visitors who previously parked along the water. Navigation through the Bassin des Récollets will also stop for the entire July-to-September bathing period under a prefectural order, removing the usual boat traffic that residents hear from their windows.

City crews have scheduled three separate operations to remove submerged scooters and other debris from the same basin on 5 July, 26 July and 23 August 2026. These dates fall inside the swimming window and are intended to maintain water quality for bathers while the redevelopment continues.

Practical effects for nearby households and users

Households along the two quays will notice fewer through-traffic movements once the vehicle limits take effect. Pedestrians and cyclists will gain continuous space on the redeveloped banks, while boat operators must reroute or pause services during the three summer months. The swimming timetable itself remains limited to late afternoon and early evening, matching the hours when many local workers and families finish their day.

Residents planning to use the new bathing area can check the city’s canal pages for daily heatwave alerts and water-quality updates. The scheduled debris-recovery dates provide advance notice for anyone who keeps a boat or waterside business in the Récollets section.
