Best tide state to fish Semaphore Jetty
The jetty projects roughly west into Gulf St Vincent, so it is exposed to the afternoon sea breeze that builds across the gulf most summer days and to any westerly weather. Mornings and the hours after the breeze drops are the calm windows; a fresh onshore wind colours the inshore water and pushes whiting off the flats. A rising tide fishes best inshore for whiting and mullet, while the turn of the tide tends to switch on the gar, squid and any night species at the deep end. After a winter front the water dirties and the squid bite in particular falls away until it clears.
What anglers target here
Anglers fishing Semaphore Jetty typically time sessions around the tide for yellowfin whiting (sand whiting), garfish, australian herring, yelloweye mullet, and southern calamari (squid).
