2026 in-season sample timeline

No individual in-season sample feed has been published for Rumilly Perouze yet. The official 2025 classification above, from the annual EU Bathing Water report, is the most current rating available for this beach.

How measurement works

Under the EU Bathing Water Directive, national authorities take water samples through the bathing season and test them for two indicator bacteria: intestinal enterococci and E. coli. Higher counts of either indicate a greater risk of contamination from sewage or agricultural runoff.

At the end of each season, the full set of results is reported to the European Environment Agency, which assigns one of four classifications — Excellent, Good, Sufficient or Poor — based on the statistical spread of the last four seasons' samples, not a single reading. That's why the rating published in spring 2026 covers the 2025 season, and why one bad sample doesn't necessarily change the rating on its own.

Frequently asked questions

Is the water at Rumilly Perouze safe right now?

It checks out — Excellent is the official 2025 EU Bathing Water rating, and 4 of 9 classified seasons on record have rated Excellent or Good. That applies to the water around Haute-Savoie.

How is bathing water quality measured?

National authorities test for two indicator bacteria — intestinal enterococci and E. coli — in water samples taken through the bathing season, then report the full season's results to the European Environment Agency the following spring, which assigns one of four classifications (Excellent, Good, Sufficient or Poor) under the EU Bathing Water Directive. Some national authorities, including Croatia's IZOR, also publish individual in-season samples ahead of that annual report; that isn't yet available for Rumilly Perouze.

How often is the water tested?

The annual classification draws on a whole season of sampling (usually 4+ samples, May–September), published just once the following spring. There's no in-season sample feed yet for Rumilly Perouze, so the annual rating above is the latest available figure.
