Is the water clean at Longoni?
Longoni sits on a stretch of coast classed as a coastal 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 Mayotte. There's parking about ~700 m from the beach.
Over the 11 classified seasons on record, 9 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, June–October is the safest bet, with August typically the peak — expect a cooler, calmer sea either side of that stretch. The nearest town, Longoni, is about ~900 m away.
“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. There's 1 place to eat near the beach — Dock's café, about ~740 m away.
Frequently asked questions
Should you swim at Longoni?
Yes. Longoni's official 2025 rating is Good — one notch below the top classification — and 9 of 11 classified seasons here have rated Excellent or Good. Its rating has also been trending the right way, moving from Sufficient to Good in 2025.
What temperature is the sea at Longoni right now?
Treat the ~28°C above as illustrative only — Longoni's live marine feed was down when this page was generated, and the figure will be replaced with a real reading automatically once it's back. That's the reading right off Mayotte. On the modeled climatology here, August usually runs warmest.
When is the best time to swim at Longoni?
For swimming, June–October is usually the best call — that's the modeled window when the sea here runs warmest. That applies to the water around Mayotte. Within that window, August is typically the single warmest month.
Where does the water quality rating come from?
Once a year, national authorities report a full season of testing for intestinal enterococci and E. coli to the European Environment Agency, which grades the season Excellent, Good, Sufficient or Poor under the EU Bathing Water Directive. A handful of countries, including Croatia via IZOR, also publish individual in-season samples ahead of that report — Longoni doesn't have that feed set up yet.
What's the easiest way to reach Longoni?
By car, there's parking about ~700 m from the beach. The nearest town is Longoni, about ~900 m away.
