Best Tide State to Fish Marion Bay Jetty
Marion Bay faces roughly south-east into Investigator Strait, which is the exposed, oceanic end of Yorke Peninsula rather than sheltered gulf water. Prevailing summer south-easterlies and any southerly swell put sea straight into the bay, while northerlies and north-westerlies come off the land and settle it. Seaweed piles up on the beaches after strong onshore winds, which ruins launching and footing and simultaneously restocks the bait supply. The autumn mullet run from Easter onward is the one seasonal certainty on this coast. Autumn and winter bring the calmest offshore-wind days at this end of the peninsula, which is exactly why neighbouring Stenhouse Bay fishes best in those months. The bloom that worked its way up the west coast in January 2026 has not spared this end of the state, and SARDI was still finding elevated pockets along Yorke as late as July 2026, so treat older catch reports with some caution.
What Anglers Target Here
Anglers fishing Marion Bay Jetty typically time sessions around the tide for yelloweye mullet, australian herring (tommy ruff), king george whiting, australian salmon, and flathead.
