About tides at Sydney Harbour
Sydney Harbour is one of the most-photographed tidal estuaries in the world — Port Jackson, the heads at North Head and South Head, the bridge and the opera house at the southern shore, and the long inner reaches running west to Parramatta. The pattern is semidiurnal: two highs and two lows about twelve and a half hours apart. Mean range is around 1.2 metres at Fort Denison, climbing toward 1.6 metres on spring tides. That's a modest swing — Sydney is far from a tidal hotspot — but the harbour's geometry concentrates flow at the heads and through narrow passages like Spit Bridge, where currents on the change of tide can run sharper than the height implies. For ferry passengers it changes nothing; for paddlers crossing the main channel, fishers working Middle Harbour, or anyone planning a swim from a tidal pool like Bronte or Mahon, the timing matters. Predictions on this page come from Open-Meteo Marine, gridded global model output. Useful for planning, not navigation-grade. The Australian Bureau of Meteorology and the NSW Maritime authority run the authoritative gauges in Sydney Harbour.
