Common questions about swimming in Germany

Is it safe to swim in Germany?
Mostly yes. 93% of Germany's 2,291 officially monitored bathing sites hold the top "Excellent" class in the 2025 assessment, but 3 sites are rated Poor — bathing there is advised against or banned all season.
Which beaches in Germany should I avoid?
The 3 rated Poor: Bad Wurzach Metzisweilerweiher, Badesee Schiesstal, Riemer See Muenchen Nordufer Badestrand. Poor means the site failed the minimum standard across four seasons of sampling.
Where is the water cleanest in Germany?
1,860 sites have held the top rating five seasons running — a far better signal than a single good year. Around Kiel, Lake Constance, Berlin you will find the densest clusters.
How often is water quality tested in Germany?
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.
