Is the water clean at Plan D'Eau de Montilliers?
Plan D'Eau de Montilliers sits on a stretch of coast classed as a lake bathing site, carrying an official EU Bathing Water rating of Good 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 Maine-et-Loire. You can park about ~130 m away.
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. On site you'll find Kids' area, Parking, and Sports facilities. Montilliers — the closest town — sits about ~400 m from here.
“Good” 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.
Frequently asked questions
Is Plan D'Eau de Montilliers a safe beach for swimming?
Generally, yes. Plan D'Eau de Montilliers holds a Good rating for 2025, the second-best classification, and 11 of 11 classified seasons have met the Excellent-or-Good bar. That said, the rating slipped from Excellent to Good in 2025, so it's worth checking for current local advisories too.
Is the sea warm at Plan D'Eau de Montilliers today?
That reading, around 27°C, is a placeholder rather than a live measurement, shown only because the marine-weather feed was temporarily unreachable; it updates automatically once the feed returns. That's the reading right off Maine-et-Loire.
Which month has the warmest sea at Plan D'Eau de Montilliers?
July–September tends to be the sweet spot for swimming here, with sea temperatures usually peaking later in that stretch. That applies to the water around Maine-et-Loire.
What's behind the water quality rating shown above?
The annual classification — Excellent, Good, Sufficient or Poor — is built from a full season of official testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring. Some national authorities (Croatia's IZOR among them) also publish individual samples during the season itself; Plan D'Eau de Montilliers isn't yet covered by that in-season feed.
Can you drive to Plan D'Eau de Montilliers?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Église, about ~330 m away. The nearest town is Montilliers, about ~400 m away.
