Best tide state to fish Coalcliff Rock Platform

The platform faces roughly east-southeast into open ocean swell, so it fishes best on a small-to-moderate sea — under about 1.5m — when the wash is alive but the lower ledges stay safe. Anything bigger pushes water right across the shelf and shuts it down for fishing and makes it dangerous to be on. A making tide into high is the prime window, covering the rock and bringing fish in close; the bite tapers as the tide drops and exposes the ledges. Westerly winds clean the water and flatten the surface, while a strong onshore easterly stirs it up and blows the float fishing out. The beach gutters fish best off the top of the tide regardless of the rock platform conditions.

What anglers target here
