Common questions about swimming in France

Is it safe to swim in France?
Mostly yes. 77% of France's 3,378 officially monitored bathing sites hold the top "Excellent" class in the 2025 assessment, but 112 sites are rated Poor — bathing there is advised against or banned all season.
Which beaches in France should I avoid?
The 112 rated Poor: Acomat, Allier Rive Gauche Base Canoe, Alzu di Gallina, Amont Du Stade, Amont Retenue, Anse de Toullain and 106 more. Poor means the site failed the minimum standard across four seasons of sampling.
Where is the water cleanest in France?
2,064 sites have held the top rating five seasons running — a far better signal than a single good year. Around Nice, Cannes, Brest you will find the densest clusters.
How often is water quality tested in France?
Through the whole bathing season. National sanitary authorities sample each official site for E. coli and intestinal enterococci, report to the European Environment Agency, and the published class reflects the last four seasons combined.

Ratings are the official season-long classification, computed from the last four seasons of sampling — not a live reading. After a storm any site can be temporarily worse; local advisories win.
