Is the water clean at Diane?
Diane is a river bathing site with an official EU Bathing Water rating of Not classified for the 2025 season — not enough samples in this year to assign an official rating. 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. You can park about ~1.4 km away.
Over the 8 classified seasons on record, 1 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. Prise d'Eau — the closest town — sits about ~2.7 km from here.
That “Not classified” 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.
Frequently asked questions
Is the water at Diane safe right now?
Not without checking first: Diane's 2025 rating is Not classified, so look for local advisories and posted flags before swimming.
How cold or warm is the water at Diane today?
Checking in on Diane right now: the water is around 30°C, per the latest reading — the “Right now” panel above tracks it live. That's the reading right off Guadeloupe.
What's the best month to visit Diane 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 Guadeloupe.
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; Diane isn't yet covered by that in-season feed.
How do I get to Diane without a car?
By car, there's parking about ~1.4 km from the beach. The nearest town is Prise d'Eau, about ~2.7 km away.
