South Australia Tide Times

About South Australia's tides

Gulf St Vincent and Spencer Gulf run on their own rules. Both are long, shallow basins where the twice-daily and once-daily tidal signals are nearly the same size — when they're in step you get a solid run, and when they cancel you get a dodge tide, with the water barely moving for a day or two around the neaps. The range amplifies heading up Spencer Gulf, where Port Germein sees some of the state's biggest tides.

For fishing, the tide that counts isn't the height — it's the movement. Each spot page below shows the day's best bite window alongside the next 14 days of tides, so you can see at a glance whether the water's actually running or you've landed on a dodge.

Common tide & swell questions

What is a dodge tide?

A South Australian speciality: around the neaps, the gulfs' two daily tides cancel each other almost completely and the water barely moves for a day or two. It happens roughly every fortnight in Gulf St Vincent and Spencer Gulf. Slack water all day means hard fishing for anything that feeds on the run — squid and garfish are the classic dodge-tide fallbacks.

Why are gulf tides so strange?

Gulf St Vincent and Spencer Gulf are long, shallow basins where the twice-daily and once-daily tidal signals are nearly the same size. When they're in step you get a decent run; when they're out of step they cancel — that's the dodge. The upshot: the printed heights matter less than whether the water is actually moving.

What is the tidal range in Adelaide?

Modest — metro jetties typically see somewhere around half a metre to two metres between low and high depending on where you are in the spring–neap cycle, and next to nothing on a dodge tide. Up Spencer Gulf it amplifies: Port Germein and the top of the gulf see some of SA's biggest tides, which is why the jetty there is a kilometre and a half long.

What is the best tide to fish in SA?

Moving water, same as everywhere — the run-in and run-out push bait around and the fish follow. On the gulfs, add one local rule: check you're not on a dodge tide before driving two hours to a Yorke Peninsula jetty. Each spot page below shows the day's best bite window alongside the tide.

How accurate are these tide times?

They're modelled (Open-Meteo, ~8 km resolution), and gulf tides are genuinely hard to model — treat the times as a guide, not a train timetable. The bite windows lean on sun and moon as much as tide, so they hold up even when the tide clock runs a bit early or late.
