Overview
- The city reported that the three supervised Seine sites (Bras Marie, Bercy and Grenelle) welcomed 120,000 bathers over an eight‑week season, a 20% rise from 2025.
- Across all monitored summer locations in Paris — the Seine sites, canal sites and four temporary outdoor pools — officials counted about 216,000 bathers and called it a record season.
- Municipal data show one third of the bathing days coincided with heatwave episodes, a factor Paris cited when describing the sites as an essential public cooling service.
- The Bras Marie and Bercy Seine sites closed briefly and intermittently in late July because of a fuel‑oil pollution incident, underlining continuing water‑quality and operational risks.
- The program began after a century‑long ban on river swimming as part of the Paris 2024 legacy and city leaders say studies are under way to open a Bassin de l'Arsenal site and to strengthen monitoring before broader expansion.
