Best tide state to fish Second Valley Jetty

This is a foul-weather refuge by Fleurieu standards. The inlet faces roughly west into Gulf St Vincent but the cliffs and the curve of the bay knock down a lot of the southerly and south-easterly that flattens the open coast, so the jetty often fishes when Rapid Bay and the beaches are blown out. A westerly or north-westerly blowing straight in is the one that ruins it, pushing chop and weed over the end. Squid and garfish both like clean, settled water, so the day or two after a blow — once the suspended weed clears — tends to fish best, and the low-light tide changes are prime.

What anglers target here

Anglers fishing Second Valley Jetty typically time sessions around the tide for southern calamari (squid), garfish, australian herring, snook, and yelloweye mullet.
