Parisians swim in the Seine for a second straight summer

Published · Researched 2026-09-22

What happened (dated facts)

On July 4, 2026, Paris reopened three free supervised Seine swimming sites for a second consecutive summer — the first time in a century the river has been swimmable two years running.
The sites operate with daily water-quality testing; weather-related closures remain possible after heavy rain.
The swimming follows the €1.4 billion cleanup for the Paris 2024 Olympics, which made the river safe for Olympic triathlon and marathon swimming.
SRN News (July 2026) frames the reopening as a summer ritual returning to Paris.

A second straight swimmable summer proves the Olympic cleanup was not a one-off — the Seine is becoming a living river again.

Covered in international press; swimming-site photos circulated on social platforms in July 2026 (specific curator lead not captured; gap disclosed).
