Flounder Fishing Guide
An ambush bottom predator found along the US Atlantic and Gulf coasts, flounder bury into sand and mud near structure and current breaks, striking as bait passes overhead — moving water matters more to triggering a bite than light or time of day.
Best conditions
- Water temperature: 60–72°F is the sweet spot.
- Light: Flexible about light — active across a range of sky conditions.
- Wind: Handles light-to-moderate wind well.
- Barometric pressure: Moderately sensitive to pressure trends.
Techniques & tips
- Live bait or bucktails fished slow and close to the bottom near inlets, channel edges, and current breaks.
- Fish moving water — flounder ambush far more actively on a running tide than at the dead calm between changes.
- Target sandy or muddy bottom near structure rather than open, featureless flats.
- Give a flounder's bite time to develop before setting the hook — they often mouth bait before committing.
Spawning behavior
Flounder typically migrate offshore to spawn in cooling water in fall, tapering inshore feeding as they stage for the move. The spawn temperature window is roughly 58–64°F.
