Other anglers prefer a falling tide. A falling tide concentrates fish in deeper holes. Falling tides also flush bait from inaccessible areas. Flounders lurk at the mouths of cuts as bait washes to them. Once the tide falls, I'll switch to fishing deeper banks with better defined drop-offs or structure.
Tides create current.
Like bass, flounders ambush prey near structure. They drop off ledge edges to watch for shrimp and baitfish passing overhead. They gather around points, shell reefs, weedy shorelines, pilings or other places where they can hide and attack. Any structure washed by strong tides may attract flounders. They'll hide behind pilings and structure on the downcurrent side.
