Full moon tides keep Mississippi Sound in late-summer mode

What's next

With water still in the mid-80s, expect the bite to stay in a warm-season pattern over the next few days rather than snapping into a fall rhythm overnight. The full moon's larger exchange should concentrate bait and current around structure during the late-morning high and the early-evening low, so the windows bracketing roughly 11 a.m.-1 p.m. and again near 6 p.m. are worth building a weekend trip around.

As surface temperatures ease toward the upper 70s over the coming weeks, the Sound's usual fall transition should follow, with redfish and spotted seatrout typically working into marsh edges and skinnier water as bait pushes inshore. Anglers planning ahead should also keep an eye on MDMR's proposed Title 22 updates moving through the public-comment process; any adopted changes could affect season or limit details before winter.

Context

Water in the low-to-mid 80s is normal for Mississippi Sound in late September. This stretch of the Gulf coast typically holds onto summer warmth longer than waters farther north, with the real cooldown not settling in until October. MDMR's run of certified records this month reflects the kind of steady, engaged effort the Sound usually sees through the tail end of hurricane season and into the early fall run. Right now this reads as a late-summer pattern still in play, not yet the fall shift that typically arrives with the first real cold front.
