Is the water clean at Coulvee?
Coulvee is a lake 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 Toilets, Kids' area, and Parking. You can park about ~80 m away.
Over the 11 classified seasons on record, 4 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. Chemillé — the closest town — sits about ~1.4 km 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. Worth noting: the rating slipped from Good to Sufficient in 2025, so it's especially worth checking the latest local advisories. There are 7 places to eat within a kilometre — La Roma is the closest, about ~610 m away.
Frequently asked questions
Is the water at Coulvee 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.
How warm is the sea at Coulvee right now?
The panel above shows a sample value of around 28°C. This is placeholder data shown because a live marine-weather feed wasn't reachable — it will be replaced automatically once the feed is available. That's the reading right off Maine-et-Loire.
What's the best month to visit Coulvee for swimming?
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 Maine-et-Loire.
What's behind the water quality rating shown above?
National authorities sample the water for intestinal enterococci and E. coli bacteria through the bathing season and report the full-season results to the European Environment Agency each spring for the season just finished, which assigns one of four annual classifications — Excellent, Good, Sufficient or Poor — under the EU Bathing Water Directive. Some national authorities, including Croatia's IZOR, also publish individual in-season sample results ahead of that annual report.
Can you drive to Coulvee?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Chemillé - Place du Château, about ~760 m away. The nearest town is Chemillé, about ~1.4 km away.
