Is the water clean at La Joseliere?
La Joseliere is a coastal 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 Sandy shore, Parking, and Sports facilities. There's parking about ~20 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, Pornic, is about ~2.0 km 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 Loire-Atlantique.

Where does the water quality rating come from?
It's based on official water samples: authorities test for intestinal enterococci and E. coli through the season, then report the full-season results to the European Environment Agency each spring, which assigns one of four grades — Excellent, Good, Sufficient or Poor. A few national authorities, including Croatia's IZOR, also publish individual samples during the season itself, ahead of that annual report — that isn't yet available for La Joseliere.
