Jervis Bay 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 Sun 17 May (range 1.7m). 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.

Jervis Bay is a drowned river valley on the NSW south coast where the sand is so white — quartz particles ground fine enough to be nearly powder — that the US Navy once evaluated it as a radar reflector. The Guinness World Records book listed it as the whitest sand in the world (the claim is contested, but the sand is genuinely remarkable). The bay is divided between Jervis Bay Marine Park, a NSW state marine protected area, and Booderee National Park, a Commonwealth territory managed by the Wreck Bay Aboriginal Community. Tidal range at Jervis Bay is 1.0 to 1.5 metres at springs. The bay opening faces northeast, providing moderate shelter from prevailing south and southeast swells; the inner bay beaches (Greenfield, Murrays, Callala) are calm and suited to snorkelling and swimming at all tide stages. The outer beaches near the entrance (Hyams, Chinamans) face more open water and get occasional swell. The bay's clear water — visibility commonly exceeds 15 metres — reflects the protected status of the marine park and the low-turbidity conditions created by the quartz sand substrate. Dolphin watching is the consistent wildlife experience: a resident pod of 80–100 bottlenose dolphins uses the bay year-round, and sightings are reliable from charter boat tours that operate without harassing the animals. Humpback whales pass the bay entrance from June through November. Little penguins (the world's smallest penguin species) nest on the rocks near Bowen Island at the northern entrance and are visible at dusk from guided tours on Greenpatch beach. The snorkelling is exceptional for a mainland Australian location. Murrays Beach within the marine park has a marked snorkel trail with fixed floats over seagrass and rocky reef; seahorses, weedy sea dragons, octopus, and blue-groper are the regular sightings. The protected status means fish density is noticeably higher than unprotected reefs of similar character. The Dent Island outer reef sites, accessed by boat, have deeper water (10–20 metres) with larger species. Hyams Beach — the settlement on the inner southwest bay — is the most visited point. The beach village has a general store, a scattering of holiday houses, and the sand that appears in every Jervis Bay photograph. It is heavily used on summer weekends; early morning (before 08:00) or weekday visits in peak season are the practical alternative. Booderee National Park entry requires a daily fee, payable at the entrance station on Jervis Bay 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.
