Mississippi Sound fall bite builds as water cools into the 60s
Water is cooling into the upper 60s to low 70s across the Sound, which is the shift that matters this week. NOAA CO-OPS station 8741533 reads 70.7°F and station 8747437 reads 68.4°F, both observed around midday. That range typically pulls inshore fish toward warmer, protected water and keeps bait moving through the estuaries. The freshest word from the agency side is that MS DMR certified three new state saltwater records for October, including a Gulf flounder taken by an angler from Creola, Alabama. That is a good reminder that fall is when the Sound's bigger bottom-oriented fish show up. MS DMR also opened an additional conditional shrimping area in Biloxi Bay on October 15, so expect more boat traffic and bait activity in and around the Biloxi Bay Channel. For species we can speak to directly, Sport Fishing Mag this week points to slow-sinking and suspending twitchbaits as the go-to for the biggest trout of the year as water cools along the Gulf coast. Coastal Angler Magazine's October inshore piece also lays out a plan for redfish, trout and flounder on artificials, built around tides, structure and the right retrieves.

What's next
The tide table gives us a clear window to plan around. Station 8741533 shows its next low at roughly 3:52 PM Central today, and station 8747437 follows with a low near 5:50 PM Central. Falling water toward those lows tends to push bait off the flats and out of marsh drains, which is when redfish stack up at the mouths of cuts and along edges.
If temperatures keep sliding as they have been, expect the bite to settle into the pattern Coastal Angler Magazine describes: fish tight to structure on the tide change, with slower retrievals as the water cools. Sport Fishing Mag's advice on slow-moving, suspending baits fits that trend, so keep a few in the box for the cooler mornings.
The moon is waxing gibbous, heading toward full. Brighter nights often shift feeding toward dawn and dusk, so early and late windows around the tide changes are the ones to prioritize. Plan around the afternoon low today, then look to the following morning's tide change for another shot.
Shrimp activity in the newly opened Biloxi Bay area, per MS DMR, is worth watching. Concentrated bait and working birds are a reliable sign that predators are close, so keep an eye on the surface near the channel edges.
Context
Late October in the Mississippi Sound is typically a transition period. Summer patterns are fading, the first real cooling trend is under way, and anglers shift from offshore and deep-structure fishing to working marsh edges, bayou mouths and channel margins. Mullet and shrimp are on the move, and that movement shapes where predators sit.
The water readings this week are in line with what we would expect for the time of year, neither early nor late. The state record certifications MS DMR announced for October are also consistent with a season when unusual and larger fish turn up in reports. As temperatures keep dropping into November, the pattern usually favors slower presentations and deeper holes on cold snaps, with warm afternoons bringing fish back shallow.
