Williamstown tides at Gem Pier

Saturday 17 October 2026 · Australia/Melbourne

Heights and times on this page are a model estimate. The model can't see the tide lag inside Port Phillip, so high and low water run early (about three hours across most of the bay, less near the heads), and near the heads it overstates the range. Use the BoM tide tables for Victoria for this area.

Best Tide State to Fish Gem Pier

Hobsons Bay is the sheltered top corner of Port Phillip, so Gem Pier fishes in southerly and south-westerly winds that make the open bay piers miserable. A strong northerly can push chop against the Williamstown shoreline but rarely shuts it down. Fresh water from the Yarra after heavy rain colours the bay and can bring bream and snapper closer to the river mouth. Dawn and dusk tide changes are the windows.

What Anglers Target Here

Anglers fishing Gem Pier typically time sessions around the tide for black bream, snapper, flathead, australian salmon, and silver trevally.
