Is the water clean at Plan D'Eau?
Plan D'Eau sits on a stretch of coast classed as a lake bathing site, carrying an official EU Bathing Water rating of Not classified for the 2025 season. Under the EU Bathing Water Directive, national authorities test for intestinal enterococci and E. coli through the season and report the results the following spring — the 2025 rating was published in spring 2026, and 2026's won't follow 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. It sits in Indre-et-Loire. There's parking about ~110 m from the beach.
That rating has been consistent: every one of the 10 classified seasons on record has come back Excellent or Good. 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. The nearest town, Chemillé-sur-Indrois, is about ~400 m away.
“Not classified” is one point on a four-step scale — Excellent, Good, Sufficient or Poor — assigned once per year from that season's water samples, not a live reading. It describes how the site performs on average across the season, not the exact water quality this afternoon; for day-to-day sea conditions, see the “Right now” and 7-day outlook panels above. There are 2 places to eat within a kilometre — Carpé Diem is the closest, about ~150 m away.
Frequently asked questions
Is Plan D'Eau safe to swim in?
Best to be careful here: Plan D'Eau's official 2025 classification is Not classified, so check for local advisories and posted flags before swimming.
What is the sea temperature at Plan D'Eau today?
The figure above (about 22°C) is placeholder data — the live marine-weather feed wasn't reachable when this page was built, and the real reading will appear automatically once it is. That's the reading right off Indre-et-Loire. On the modeled climatology here, August usually runs warmest.
When is the best time to swim at Plan D'Eau?
For swimming, July–September is usually the best call — that's the modeled window when the sea here runs warmest. That applies to the water around Indre-et-Loire. Within that window, August is typically the single warmest month.
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 Plan D'Eau.
What's the easiest way to reach Plan D'Eau?
By car, it's easy — parking is right by the beach. The nearest town is Chemillé-sur-Indrois, about ~400 m away.
