Merimbula 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 Australia/Sydney local. Folk tradition, not a scientific forecast.

Next spring tide on Tue 05 May (range 1.1m). Next neap on Fri 08 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.

Merimbula is a fishing town on the Sapphire Coast — the stretch of NSW south coast below Batemans Bay, named for the clarity of the water rather than any gemstone deposit — that has kept its working character while accommodating enough summer tourism to sustain the town economically through the colder months. Merimbula Lake, a large tidal estuary that cuts into the town, is the geographic feature that organises everything: the town sits between the lake and the open ocean beach, and the lake provides calm water for kayaking, fishing, and swimming in a protected environment separate from the surf. Tidal range at Merimbula is 1.5 to 2.0 metres at springs — mid-range south NSW coast. The lake entrance channel is tidal; outgoing flow can be strong enough to affect kayakers near the bar. The ocean beach (Short Point and Main Beach) picks up southeast and east swells from the Tasman Sea. The south coast of NSW receives consistent swell year-round, with larger, more powerful waves in autumn and winter from Southern Ocean storm systems. The oyster industry operates on the lake — Merimbula Lake oysters are sold locally and distributed through Sydney restaurants. The oyster leases visible from the kayak routes on the upper lake are an active, working element of the estuary. Guided tours run from the Merimbula Wharf, combining oyster tasting with lake ecology context. The lake supports black swans, pelicans, herons, and migratory wading birds that use the tidal flats on the ebb. Diving in the offshore waters is organised around the Merimbula artificial reef (old tyres and structures placed 3 km offshore in the 1990s) and the natural rocky reefs around Short Point. Grey nurse sharks are present at some deeper sites offshore; the area is within the distribution range for these animals. Whale watching from July through November as southern right whales and humpbacks move along the NSW coast is feasible from the headlands or charter boats. Ben Boyd National Park begins immediately south of Merimbula and extends to the Victorian border — coastal heath, eucalyptus forest, and ocean cliffs with limited development pressure. The Light to Light walk (31 km over 2–3 days) runs between Green Cape Lighthouse and Boyd Tower through the park on a maintained trail. Day sections are accessible from the Merimbula end via the Potoroo Palace wildlife park access road. 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.
