The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Indian/Reunion local. Folk tradition, not a scientific forecast.

Next spring tide on Sun 17 May (range 0.6m). Next neap on Fri 22 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

L'Ermitage-les-Bains is a small resort community 3 km south of Saint-Gilles, occupying a section of Réunion's western fringing reef lagoon that is widely regarded as the island's best accessible snorkelling and freediving zone. The lagoon between the beach at L'Ermitage and the reef crest holds a resident population of green turtles (Chelonia mydas), reef fish, and living coral in a depth range of 1 to 3 m at mean water level — shallow enough to snorkel comfortably from the beach without a boat. The tidal regime at L'Ermitage is semidiurnal with the same spring range as the neighbouring Saint-Gilles coast: approximately 0.9 m springs, 0.4 m neaps. The small range interacts with the lagoon's very shallow bathymetry to produce marked tidal-state dependence on the snorkelling experience. At low water springs the seagrass beds in the inner lagoon can reduce to 0.3 to 0.5 m of depth — comfortable for wading but too shallow for horizontal snorkelling over the seagrass without disturbing the bottom. Green turtles grazing on the seagrass are more easily and closely observed at this low-water state, as the animals cannot dive deep to evade and often continue feeding while observers float slowly overhead. At mid-tide and above, the lagoon depth over the seagrass zones increases to 1.0 to 2.0 m and snorkelling is comfortable for all ability levels. The inner face of the reef crest — the most species-rich zone — holds hard and soft coral, reef fish (parrotfish, wrasse, triggerfish, moray eels), and the occasional blacktip reef shark (Carcharhinus melanopterus) cruising the crest. Accessing the reef crest requires the same minimum water depth as at Saint-Gilles: mid-flood or above for fin clearance on the crest crossing. The reef snorkel path at L'Ermitage that most operators and guides use runs parallel to the inner face of the reef crest, from north of the main beach access point south toward the La Saline boundary. The path stays on the lagoon side of the crest and requires at least 0.6 m of water over the crest to navigate without contact. On incoming water from mid-flood onward, the path is clear and the current on the inner crest face is mild. On the ebb below mid-tide, the current strengthens as water drains through the crest channels, and the shallowing depth requires care. Green turtle observations at L'Ermitage are not incidental. The turtle population using the lagoon seagrass is resident — the same individuals return over years — and the snorkelling encounter rate is high enough that L'Ermitage has become one of Réunion's recognised marine wildlife experiences. The turtles are legally protected; established code of conduct requires floating quietly without chasing, touching, or approaching closer than 2 m when the turtle is resting. The animals habituate to calm, non-pursuing snorkellers and will often remain in the seagrass for extended feeding sessions. The Route du Littoral, the major coastal motorway linking Saint-Denis to the resort towns, passes directly behind L'Ermitage beach. The road runs on viaduct and against the basalt cliff in several sections and is periodically closed to rockfall. Travel time from Saint-Denis varies depending on route conditions; during closures, traffic diverts inland via the Route des Tamarins (RN1a). The Réunion prefecture maintains real-time road closure information on its website and via local radio broadcast. Predictions for L'Ermitage-les-Bains come from Open-Meteo Marine, a gridded global ocean model; accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 m on height above chart datum.
