The Paris city hall is considering extending the Seine bathing season into September, inspired by the positive reception and high turnout, with discussions about making these sites a permanent feature of the city's recreational offerings.

The initiative, which initially faced skepticism, has proven successful, with officials emphasizing the importance of continued efforts to promote Seine swimming.

The success of this summer’s Seine swimming sites suggests plans for ongoing events in 2026, with interest from around thirty other cities in the Greater Paris area to develop their own supervised Seine swimming sites.

Public and official interest in Seine swimming has grown significantly, contributing to ongoing discussions about the feasibility of establishing permanent bathing sites along the Seine.

Since opening in mid-June 2025, three designated bathing sites—Bercy, Bras Maris, and Grenelle—have attracted over 75,600 bathers despite 13 days of closure due to health concerns, highlighting strong public demand.

The sites have proven especially popular during the hot weather of August, following a rainy July that initially limited water quality, with thousands of visitors enjoying the water.

In July alone, around 35,000 people swam in the Seine, with an additional 23,500 entries during the hot week of August 15, reflecting the public’s enthusiasm supported by a €1 billion investment in pollution reduction ahead of the 2024 Olympics.

Originally scheduled to close on August 31, 2025, the City of Paris is considering extending the Seine bathing sites' operation by one to two weeks due to their popularity, pending approval from regional authorities.

There are plans to relocate the Bras Maris site to allow for all-day operation, as current restrictions due to maritime traffic cause it to close daily at 11 a.m.

Notably, two elderly women, Brigitte and Nadine, enjoyed their first swim at the Bercy site on August 18, describing the water as good and odorless, and expressing regret for not trying it sooner.
