Is the water clean at Plage de Castelnaud?
Plage de Castelnaud is a river bathing site with an official EU Bathing Water rating of Good for the 2025 season — meets the EU bathing-water 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 Toilets, Beach bar, and Restaurant. There's parking about ~170 m from the beach.
Looking to avoid the busiest weeks? The water is typically warmest around August, with the most reliable swimming window running July–September; outside that stretch you'll find a cooler sea but a quieter beach. That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. The nearest town, Castelnaud, is about ~200 m away.
Worth remembering: “Good” 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 Dordogne. There are 13 places to eat within a kilometre — La Plage is the closest, about ~150 m away.

What is the sea temperature at Plage de Castelnaud today?
For Plage de Castelnaud, the ~25°C figure above is a stand-in value, not a live reading — the marine-weather feed was unreachable when the page last built, and it'll swap in automatically once the feed responds again. That's the reading right off Dordogne. On the modeled climatology here, August usually runs warmest.
When is the best time to swim at Plage de Castelnaud?
For the warmest water, aim for July–September — that's when the modeled sea temperature is typically at its best. That applies to the water around Dordogne. Within that window, August is typically the single warmest month.
Who measures the water quality rating, and how?
Once a year, national authorities report a full season of testing for intestinal enterococci and E. coli to the European Environment Agency, which grades the season Excellent, Good, Sufficient or Poor under the EU Bathing Water Directive. A handful of countries, including Croatia via IZOR, also publish individual in-season samples ahead of that report — Plage de Castelnaud doesn't have that feed set up yet.
Is there parking near Plage de Castelnaud?
By car, it's easy — parking is right by the beach. The nearest town is Castelnaud, about ~200 m away.
