Paris Council Upgrades Canal Saint-Martin to Combat Urban Heat

Paris City Hall opened a free supervised swimming zone in the Canal Saint-Martin Récollets basin on June 22, 2026, with daily hours from 3pm to 9pm during heatwave periods. The move forms part of the 10th arrondissement city council's ongoing updates on the canal, which city officials presented at a public meeting on June 4, 2026.

The timing reflects immediate pressure from summer heat, with the council balancing short-term public access against longer infrastructure work. Paris has chosen to open the water for supervised use while construction continues, a pattern seen in other dense cities that combine seasonal recreation with major public-space renewal.

Swimming Hours and Local Access

After the initial daily schedule, swimming will move to Sundays only from 2pm to 6pm between July 5 and August 30, 2026, pending water quality and safety checks. The Récollets basin site remains the designated location, keeping the facility within the 10th arrondissement and directly tied to the redevelopment corridor.

By maintaining free entry and on-site supervision, the council provides a low-cost option for residents during peak heat, consistent with practices in other European and North American cities that have opened urban canals or rivers under controlled conditions.

Redevelopment Progress and Milestones

The larger canal project includes 3.4km of new cycling paths and 10,400 m² of pedestrian space, with final delivery now set for December 2027 after an extension beyond the original 2026 target. Recent work delivered 45 new trees and nearly 2 km² of vegetation, while the cycling path on Quai de Valmy is due for completion by late April 2026.

These steps show the council prioritising cooling measures and active transport alongside the swimming program. The June 4 public meeting allowed residents to review the balance sheet and remaining phases, giving direct input on how the transformed canal will function once complete.

Compared with similar cities that have undertaken parallel waterway projects, Paris has kept the swimming zone operational during construction rather than closing sections entirely, which supports continuous public benefit while the 2027 deadline approaches.

Residents can monitor updates through the 10th arrondissement city council channels ahead of the Sunday-only schedule starting July 5 and the final project handover in December 2027.
