Is the water clean at Rumilly Perouze?
Rumilly Perouze is a lake bathing site with an official EU Bathing Water rating of Excellent for the 2025 season — the highest official classification under the EU bathing-water assessment. That annual classification comes from the EU Bathing Water Directive: national authorities test for two indicator bacteria, intestinal enterococci and E. coli, throughout the bathing season, then report the full-season results to the European Environment Agency (EEA) the following spring — the 2025 season's rating was published in spring 2026, and the 2026 season won't be rated until spring 2027. In addition to that yearly rating, some national authorities — for Croatia, the national environmental authority — publish individual water sample results during the season itself, ahead of the annual report. On site you'll find Toilets, Restaurant, and Kids' area. You can park about ~110 m away.
Over the 9 classified seasons on record, 4 have come back Excellent or Good — a track record worth checking each year rather than assuming. The most reliable swimming window here typically runs from July–September, with the sea usually at its warmest around August. Outside that window the water is cooler and often quieter. It's been a consistently reliable spot too — the rating has held at Excellent for 2 straight years. Boussy — the closest town — sits about ~1.6 km from here.
Worth remembering: “Excellent” isn't a live reading, it's an annual grade — Excellent, Good, Sufficient or Poor — set once a year from that season's water samples and describing the average, not this afternoon's conditions. For what the sea is doing right now, check the “Right now” panel and 7-day outlook above. It sits in Haute-Savoie. There are 3 places to eat within a kilometre — Snack is the closest, about ~70 m away.
Frequently asked questions
Is the water at Rumilly Perouze safe right now?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 4 of the 9 classified seasons on record have rated Excellent or Good. It's also held steady at Excellent for 2 straight years.
How warm is the sea at Rumilly Perouze right now?
That's placeholder data, not a live measurement: Rumilly Perouze's marine-weather feed couldn't be reached, so the panel above is showing an estimated ~24°C until the real feed comes back. That's the reading right off Haute-Savoie.
Which month has the warmest sea at Rumilly Perouze?
July–September tends to be the sweet spot for swimming here, with sea temperatures usually peaking later in that stretch. That applies to the water around Haute-Savoie.
What does the water quality rating actually measure?
The grade comes from a full season of official sampling for intestinal enterococci and E. coli, reported to the European Environment Agency each spring under the EU Bathing Water Directive, which assigns Excellent, Good, Sufficient or Poor. Some countries (Croatia, via IZOR) also publish individual in-season samples ahead of that report; Rumilly Perouze doesn't have that feed yet.
How do you get to Rumilly Perouze?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Base de Loisirs, about ~90 m away. The nearest town is Boussy, about ~1.6 km away.
