Pulau Ubin tide times

Pulau Ubin sits in the Johor Strait between Singapore and the Malaysian state of Johor, approximately 1.5 kilometres from Changi Point on the Singapore mainland. It is the second-largest of Singapore's offshore islands at roughly 10 square kilometres, and it is the one that has most successfully resisted the city-state's transformation. There are no private cars on Ubin. The roads — unpaved laterite tracks through secondary forest and past disused granite quarry ponds — carry bicycles, the occasional electric village cart, and on weekends, a steady flow of visitors walking, cycling, and birdwatching. Wild boar move through the forest at dawn and dusk, unconcerned by the slow human traffic. Monitor lizards sun themselves on the quarry pond banks.

The bumboat crossing from Changi Point Ferry Terminal takes 10 minutes and runs on demand — when enough passengers gather at the terminal (nominally 12), the boat goes. There is no fixed timetable. In practice, waiting time on weekdays is 15 to 30 minutes; on weekends the boats run almost continuously. The bumboat landing on Ubin's southern shore deposits visitors in the small kampung (village), where bicycle rental operations line the main track. The kampung retains the character of a 1960s Singapore village — coffee shops serving nasi lemak and teh tarik, a Chinese temple, a small hardware store.

The Johor Strait between Pulau Ubin and the Malaysian mainland narrows to approximately 500 metres in places and has a spring tidal range of approximately 2.7 metres, driven by the same Strait of Singapore tidal system that affects the southern islands. The tidal stream through the strait runs at 1 to 2 knots at peak spring flow, east on the flood tide and west on the ebb. This current is significant for small boat operators, paddlers, and swimmers — the strait is not a safe swimming environment at peak tidal flow, but it is crossable by experienced sea kayaker at slack water.

Chek Jawa Wetlands occupies the eastern tip of Pulau Ubin and is managed as a nature reserve by the National Parks Board. The wetlands are accessible via a 1.3-kilometre boardwalk from the main kampung track — a 20-minute bicycle ride or 40-minute walk. The boardwalk crosses mangrove and seagrass lagoon environments, and the Jejawi Tower at the boardwalk's midpoint gives a view over the entire wetland system. The inter-tidal sandflat is visible from the boardwalk at low water; the lagoon area is only opened to visitors during scheduled low-water access windows (check NParks for current dates).

Birdwatching on Pulau Ubin is productive year-round and exceptional during the northeast monsoon migration (October to January), when raptors funnel through the Johor Strait corridor. Crested goshawk, grey-headed fish eagle, and white-bellied sea eagle are resident. During migration, Oriental honey buzzard, Japanese sparrowhawk, and Chinese goshawk move through in numbers. The coastal forests near Chek Jawa hold the last population of the changeable hawk-eagle on Singapore territory.

For families with children, Ubin offers a low-key coastal day: bicycle rental at the kampung, a slow circuit of the main tracks through forest and past quarry ponds, lunch at the kampung coffee shop, and the boardwalk at Chek Jawa. The quarry ponds are connected to the sea and tidal, though their exchange with the strait is restricted by the quarry geometry — water level in the ponds fluctuates 0.5 to 1 metre with the tide, noticeably less than the full strait range.

Predictions on this page 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 metres on height — model-derived, not from a local gauge. The local tide authority is the Maritime and Port Authority of Singapore (MPA), which publishes annual tide tables for Singapore Strait reference stations including the Johor Strait.
