Is the water clean at Plan D'Eau de Grezille?
Plan D'Eau de Grezille sits on a stretch of coast classed as a lake bathing site, carrying an official EU Bathing Water rating of Excellent 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 ~100 m away.
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. Grézillé — the closest town — sits about ~200 m from here.
That “Excellent” 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. It's been a consistently reliable spot too — the rating has held at Excellent for 6 straight years. There are 2 places to eat within a kilometre — La Source St Anne is the closest, about ~180 m away.
Frequently asked questions
Is the water at Plan D'Eau de Grezille safe right now?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 10 of the 10 classified seasons on record have rated Excellent or Good. It's also held steady at Excellent for 6 straight years.
How cold or warm is the water at Plan D'Eau de Grezille today?
That's placeholder data, not a live measurement: Plan D'Eau de Grezille's marine-weather feed couldn't be reached, so the panel above is showing an estimated ~27°C until the real feed comes back. That's the reading right off Maine-et-Loire.
Which month has the warmest sea at Plan D'Eau de Grezille?
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.
How is the water quality rating measured?
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 Grezille isn't yet covered by that in-season feed.
How do I get to Plan D'Eau de Grezille without a car?
By car, it's easy — parking is right by the beach. The nearest town is Grézillé, about ~200 m away.
