What kind of beach is this?
This beach belongs to a small coastal village. It's usually calmer than a resort or town beach, though a popular village spot can still fill up on the best summer days.

Is the water clean at Chateau?
Chateau is a coastal bathing site with an official EU Bathing Water rating of Sufficient for the 2025 season — meets the minimum EU standard in the latest annual 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 Sandy shore, Parking, and Benches. You can park about ~130 m away.
Over the 7 classified seasons on record, 0 have come back Excellent or Good — a track record worth checking each year rather than assuming. If you're timing a visit around water temperature rather than crowds, July–September is the safest bet, with August typically the peak — expect a cooler, calmer sea either side of that stretch. Kersaint — the closest town — sits about ~800 m from here.
That “Sufficient” label comes from a full season of official water sampling, not a single test — it's one step on a four-point scale (Excellent, Good, Sufficient, Poor) reassessed once a year. Today's actual conditions can differ from the seasonal average, so for a live snapshot see the “Right now” and 7-day outlook panels above.
Frequently asked questions
Is the water at Chateau safe right now?
Generally yes, but with caution. Its official 2025 rating is Sufficient — the minimum passing grade — so check for posted local advisories before swimming.
Is the sea warm at Chateau today?
As of the latest update, the sea temperature at Chateau is around 19°C — see the “Right now” panel above for live conditions. That's the reading right off Finistère.
What's the ideal time of year to swim at Chateau?
July–September is typically the most reliable swimming window, with the sea usually warmest in the second half of summer. That applies to the water around Finistère.
What's behind the water quality rating shown above?
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; Chateau doesn't have that feed yet.
How do I get to Chateau without a car?
By car, it's easy — parking is right by the beach. The nearest town is Kersaint, about ~800 m away.
