Singapore

Singapore is a single-island city-state at the southern tip of the Malay Peninsula, fronting the Strait of Malacca to the west and the South China Sea to the east, with the Singapore Strait running along the southern shore between the main island and the Riau archipelago of Indonesia. The tide here is a mixed semidiurnal signal — two highs and two lows of unequal size most days, with the asymmetry between the higher high and the lower low varying through the lunar month and shifting toward strongly diurnal at certain phases. Mean range at the Tanjong Pagar reference gauge in the harbour is about 1.7 metres, climbing past 2.7 metres on the largest spring tides and dropping near 0.7 on neaps. The Strait of Malacca to the west and the South China Sea to the east each push their own tidal wave at Singapore, and the small phase difference between them produces the local pattern. Monsoon influence is significant: the north-east monsoon from December through March piles water against the eastern shore at Pasir Ris and East Coast Park, and the south-west monsoon from June through September does the same on the western side at Tuas and Jurong. The reclaimed land at Marina Bay, the floating fish farms in the Johor Strait, the working anchorage of one of the world's busiest ports, and the recreational coastline at Sentosa, Pulau Ubin, and the Southern Islands all read the table for different windows. The Maritime and Port Authority of Singapore publishes the authoritative tide tables and operates the gauge network; Open-Meteo Marine drives the gridded predictions on this site.
