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 Asia/Singapore local. Folk tradition, not a scientific forecast.

Last spring tide on Tue 19 May (range 2.6m). Next neap on Wed 20 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.

Pulau Ubin sits in the Strait of Johor between Singapore's northeastern shore and the Malaysian state of Johor, a 15-minute bumboat ride from Changi Point Ferry Terminal at a flat fare that has stayed unchanged for years. It is Singapore's last functioning kampung landscape: granite quarries long since quieted, rubber and durian plantations, wooden village houses on stilts, a few small shops selling cold drinks and provisions. The contrast with the mainland is deliberate — the Singapore government has preserved Ubin as a heritage and nature reserve rather than clearing it for development, and that decision has made it one of the most unusual places reachable from a global city within half an hour. The Chek Jawa Wetlands on the island's eastern tip are the primary reason most visitors time their trip against the tide table. Chek Jawa is a rare overlap of six coastal ecosystems — rocky shore, sandy shore, seagrass lagoon, coral rubble, mangrove, and coastal forest — concentrated in a compact headland accessible via a 1 km boardwalk. The boardwalk is open at all tide states, but the intertidal zone below it only reveals itself on the spring low tides. During a spring low — the lowest water of the month, occurring in the three to four days around new and full moons — the exposed flats extend well beyond the boardwalk edge. Guided intertidal walks take participants across the seagrass and sand to sea stars, anemones, fiddler crabs emerging from their burrows in their hundreds, mudskippers navigating the mangrove roots, and the occasional horseshoe crab in the shallows. The accessible intertidal window at Chek Jawa is approximately 2 hours either side of the spring low. On neap tides, the boardwalk is the only route and the intertidal zone remains submerged. The Straits of Johor runs a semidiurnal tidal regime — two highs and two lows of roughly similar size each day — with a spring range of 2.0 to 2.5 m. This range is enough to expose broad flat terrain at Chek Jawa on the lowest spring tides, and to bring the water back up to the boardwalk base on the highest spring highs. Tidal currents in the strait run 0.5 to 1.5 knots depending on the phase; kayakers crossing from Changi Point use the flood to ease the 1 km crossing, and the small ferries serving the Johor Bahru waterfront run around the clock regardless of tidal state. The rest of the island is accessible by bicycle — rentals at the main jetty for a few dollars, no motor vehicles permitted for visitors, 10 km of paved road and gravel track connecting the jetty, the quarry ponds, Teck Seng's Place heritage zone, Noordin Beach on the north coast, and the kampung clusters along the main road. Wild boar and monitor lizards are common across the island; both are habituated to people but should be given space. Boars with piglets can be territorial when surprised at close range. Anglers work the jetty pilings, the granite outcrops on the northern coast, and the channel edges for mangrove jack, grouper, and queenfish on the incoming tide; the flood current along the rocks is the productive window. Photographers come for two specific things: the wetlands boardwalk at golden hour on a spring low, and the view from the main road of Singapore's industrial container terminals rising behind kampung rooftops and palm trees — an image of two Singapores in one frame. NParks manages the Chek Jawa guided walks programme; booking is required and places are listed on the NParks website each month keyed to the spring low-tide calendar.
