Is the water clean at Sainte-Marguerite?
Sainte-Marguerite is a coastal 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 Lifeguard, Sandy shore, and Toilets. You can park about ~390 m away.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. 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 11 straight years. Pornichet — the closest town — sits about ~2.9 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 Finistère. There's 1 place to eat near the beach — Domaine Ker Juliette, about ~480 m away.
Frequently asked questions
Is the water at Sainte-Marguerite safe right now?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 11 of the 11 classified seasons on record have rated Excellent or Good. It's also held steady at Excellent for 11 straight years.
Is the sea warm at Sainte-Marguerite today?
That reading, around 24°C, is a placeholder rather than a live measurement, shown only because the marine-weather feed was temporarily unreachable; it updates automatically once the feed returns. That's the reading right off Finistère.
What's the best month to visit Sainte-Marguerite for swimming?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around Finistère.
What's behind the water quality rating shown above?
The annual classification — Excellent, Good, Sufficient or Poor — is built from a full season of official testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring. Some national authorities (Croatia's IZOR among them) also publish individual samples during the season itself; Sainte-Marguerite isn't yet covered by that in-season feed.

By car, there's parking about ~390 m from the beach. By bus, the nearest stop is Sables d'Or, about ~100 m away. The nearest town is Pornichet, about ~2.9 km away.
