Is the water clean at Plan D'Eau - la Deome?
Plan D'Eau - la Deome 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 Loire. You can park about ~50 m away.
That rating has been consistent: every one of the 4 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. Saint-Sauveur-en-Rue — the closest town — sits about ~800 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 4 straight years. There's 1 place to eat near the beach — Snackbar Java, about ~10 m away.
Frequently asked questions
Is Plan D'Eau - la Deome a safe beach for swimming?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 4 of the 4 classified seasons on record have rated Excellent or Good. It's also held steady at Excellent for 4 straight years.
Is the sea warm at Plan D'Eau - la Deome today?
That reading, around 24°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 Loire.
What's the ideal time of year to swim at Plan D'Eau - la Deome?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around 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.
How do I get to Plan D'Eau - la Deome without a car?
By car, it's easy — parking is right by the beach. The nearest town is Saint-Sauveur-en-Rue, about ~800 m away.
