Is the water clean at Plage Citerne Quarante Six?
Plage Citerne Quarante Six 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 Réunion. You can park about ~70 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 Lifeguard, Showers, and Toilets. Saint-Leu — the closest town — sits about ~1.2 km 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. There are 8 places to eat within a kilometre — Snack de Four à Chaux is the closest, about ~50 m away.
Frequently asked questions
Is Plage Citerne Quarante Six a safe beach for swimming?
It's a solid yes: Plage Citerne Quarante Six is rated Good for 2025, the second tier on the EU scale, backed by 11 of 11 classified seasons at Excellent or Good. That said, the rating slipped from Excellent to Good in 2025, so it's worth checking for current local advisories too.
How cold or warm is the water at Plage Citerne Quarante Six 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 Réunion.
What's the ideal time of year to swim at Plage Citerne Quarante Six?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around Réunion.
How is the water quality rating measured?
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.

By car, it's easy — parking is right by the beach. By bus, the nearest stop is Gendarmerie de Saint-Leu, about ~190 m away. The nearest town is Saint-Leu, about ~1.2 km away.
