Kaohsiung tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

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

Next spring tide on Tue 19 May (range 1.4m). Last neap on Sat 16 May. 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.

Kaohsiung is Taiwan's largest port and southern metropolis, built around a deep harbour on the South China Sea coast. The tidal regime is mixed semidiurnal — two highs and two lows per day of unequal height — with a mean range of approximately 1.0 to 1.2 m relative to Chart Datum. Spring tides push toward 1.5 m; neap tides compress the daily range to under 0.6 m. The harbour entrance at Qijin Peninsula is the defining hydrographic feature of the city's coastline: the channel is narrow and both tidal current and vessel traffic run through it continuously. Qijin Island (Cijin Island) lies just inside the harbour mouth, reachable by a three-minute ferry from the Gushan terminal — the ferry crossing is tidal and vessel-traffic-dependent, running on a short-headway schedule. The Qijin Peninsula beach on the island's Pacific-facing western side is Kaohsiung's nearest ocean swimming beach, a narrow strip backed by the old lighthouse hill and the cannon-battery park above. The Love River (Ai He) runs from Zuoying in the north through the city centre to the inner harbour basin at Yancheng — a 12 km urban waterway. At low tide, the lower reaches of the river partially expose the river bed, and the tidal backwater from the harbour raises the river level on the flood. Evening riverboat tours on the Love River are a standard Kaohsiung activity; the water level and reflections are best at high tide when the river is full. The harbour itself handles around 10 million TEU annually; the Cijin Cross-Harbour Tunnel (bicycle and pedestrian) and the Qijin ferry are the two links between the peninsula and the main city, giving residents and visitors the option of a beach day reachable by bicycle from the urban core. The Central Weather Administration (CWA) is the authoritative source for tidal predictions in Taiwan; Open-Meteo Marine supplements with gridded model data accurate to approximately ±45 minutes on timing and ±0.2–0.3 m on height.
