Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

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/Maldives local. Folk tradition, not a scientific forecast.

Next spring tide on Fri 08 May (range 0.7m). Next neap on Mon 11 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.

Rangali Island sits in the far southwest corner of South Ari Atoll, one of the most remote inhabited points in the atoll group. The island is the site of a well-known luxury resort positioned across two small islands — Rangali and Rangalifinolhu — connected by a 500 m walkway over the shallow lagoon. The house reef at Rangali drops to 30 m within a short swim from the beach; the underwater visibility and reef condition at this remote outer-atoll position is among the best in the Maldives. The tidal regime is mixed with diurnal inequality: spring range approximately 0.9–1.2 m above Chart Datum, with occasional diurnal days. The lagoon between the two Rangali islands is shallow (0.3–1.0 m at mean water level); at high water it is a tranquil, waist-to-chest-deep passage, and at low water the central section shallows to 10–20 cm — walkable but not swimmable. The walkway between the islands is constructed above the high-water line and remains above water at all tide states. The house reef on the ocean face of Rangali drops steeply within 20 m of the beach. At high water the reef crest sits at 0.3–0.5 m depth; snorkellers can approach the drop-off without difficulty. At low water the reef crest may be exposed or at 5–10 cm depth, making direct entry from the beach impractical — entry by boat or from the resort jetty (which maintains depth at all tide states) is the standard approach. The full drop-off from crest to 30 m is accessible at all tide states by entering from the deeper lagoon-side jetty. South Ari Atoll's position on the western edge of the Maldives chain means the ocean face of the atoll is exposed to the full Indian Ocean swell from the W and SW during the SW monsoon (May–November). Swell at Rangali during this period can reach 1.0–2.0 m on the exposed reef face; the lagoon side is sheltered. The NE monsoon (December–April) is the classic calm season with flat seas and NE trade wind conditions. Water temperature at Rangali is 27–29°C from November through April (NE monsoon) and 25–27°C from May through October (SW monsoon) when upwelling cools the surface marginally. Visibility on the house reef reaches 20–30 m in the NE monsoon season and 10–20 m in the SW monsoon when plankton concentrations increase. Tide predictions here come from Open-Meteo Marine: accuracy ±45 min / ±0.2–0.3 m. Maldives Meteorological Service publishes official sea-level data. The luxury resort on Rangali and Rangalifinolhu islands is built on an entirely over-water and beach villa model; no other form of accommodation exists on the islands. The over-water villas have direct lagoon access steps; the lagoon depth at the villa steps is 0.5–1.2 m at high water and 0.2–0.5 m at low, making direct water entry from the villa easy at high water and requiring descent of additional steps at low. The house reef drop-off is accessible by a 100–150 m swim from the ocean-side beach villas; the reef crest at this distance is at 0.3–0.5 m at high water. The extreme remoteness of Rangali Island in the SW corner of South Ari Atoll means the resort is effectively self-contained; supplies arrive by seaplane and speedboat. The resort's over-water restaurant built entirely below the ocean surface, with transparent panels giving views into the reef below, is a frequently referenced example of architectural integration with the tidal marine environment. The depth of the water beneath the restaurant varies with the tide; at low water the seabed is closer to the glass and the available light for the marine life below is reduced. The 500 m inter-island walkway at Rangali, crossing the shallow lagoon above the tidal water, is a physical experience of the Maldivian tidal environment that no amount of shore-side description replaces.
