Flounder Closure Looms for Louisiana as Gulf Holds Summer Warmth

What's next

Expect water temps to hold near current levels through the week with no sign of a fall cooldown yet, keeping the bite pattern closer to late-summer behavior than a true autumn transition. Tides at station 8760922 bring a high near 9:33 a.m. and a low around 4:18 p.m. local time today, with a high near 11:11 a.m. at station 8761724, worth building a morning trip around if targeting the incoming push into back-bay drains before the Oct. 15 flounder closure.

With the closure a week out, this is the window to fish flounder stacking at bayou mouths and lake drains, a pattern Sport Fishing Mag describes as typical of the Calcasieu Estuary's inshore water this time of year. Weekend planning should lean on the morning tide stages above; a Waning Crescent moon offers modest tidal push rather than the bigger swings of a full or new moon.

Context

Early October water temps in the low 80s are normal for the Louisiana Gulf Coast and Delta, which stays in a late-summer holding pattern well past the calendar equinox. The region's inshore season typically shifts into true fall structure, with flounder staging at outflows and specks and reds pushing into marsh drains, only once temps start easing into the 70s, which hasn't happened yet here. The approaching flounder closure (Oct. 15 to Nov. 30) is the clearest seasonal marker on the calendar right now, timed to protect the species during its fall spawning migration, and is worth checking against current state regs before planning a harvest trip.
