SOLUNAR FORECAST

Fishing windows · 7-day rating

The angler tradition that rates each day for fish-bite likelihood using moon transits and rise/set. One to five stars, not a scientific forecast.

SPRING AND NEAP CYCLE

Cycle dates near Sydney Harbour

Next spring tide on Fri 01 May (range 1.3m). Next neap on Tue 28 Apr.

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.

EDITORIAL

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.

COMMON QUESTIONS

Tide questions about Sydney Harbour

When is the next high tide at Sydney Harbour?
The hero block shows the next high tide at Sydney Harbour in local Sydney time, height above MSL. The 7-day table covers daily highs and lows. Tidal pools like Bronte, Bondi Icebergs, and Mahon refill on the high and drain on the low — pair the tide table with sunrise/sunset from the sun/moon block above for swim planning.
What's the typical tide range at Sydney Harbour?
Mean range at Fort Denison is about 1.2 metres. Spring tides — around new and full moons — push to roughly 1.6 metres, neaps drop to around 0.8 metres. The Australian east coast is well outside any major resonant tidal basin, so swings are modest compared to Europe or the Bay of Fundy.
Where do these tide predictions come from?
Open-Meteo Marine, a gridded global ocean model. That's model-derived output, not a measured gauge — accurate enough for planning a paddle or a swim, but not navigation-grade. For the official Sydney Harbour tide data, the Australian Bureau of Meteorology operates the Fort Denison gauge and publishes tide tables.
Why are tidal pools like Bronte popular at low tide?
Sydney's harbourside and ocean tidal pools fill from incoming swell at high tide and drain partially on the low. At low tide the water is calmer, the pool walls are exposed, and the deeper end of pools like Bronte and Mahon becomes safer for less-confident swimmers. Watch for swell-driven washover at the top of the cycle in big sea states.
Is this safe to use for navigation?
No. For piloting in Sydney Harbour use the Australian Bureau of Meteorology's tide tables, the Australian Hydrographic Office charts, and NSW Maritime notices. Open-Meteo's gridded data is useful general-planning information, not a navigational source.
