The best time of the year to catch flounders is the late summer/early fall months. But they can be caught regularly during the spring and summer as well. The flounders migrate offshore during the colder months to spawn, so they'll be more abundant at the beach as they move from the inshore estuaries to deeper water.
When should I go gigging?
Although gigging can be done in the daylight hours, it is far more fun and productive to gig for Flounder on a very dark night. Gigging a few hours before dead low tide or at low tide before the tide starts to come in will bring you the best results as the Flounder will be closer to shore.
What tide is best for floundering?
The outgoing high tide is the best tide to catch flounder. Flounder rely upon the outgoing tide to bring them shrimp, crabs and fish to their hidden ambush points. They like to hide in strategically located spots that will make it easy for them to catch their prey as the tide brings the food right to them.
