Mississippi Sound holds summer warmth as snook push toward fall
Mississippi Sound is still holding onto summer heat heading into the third week of September, with NOAA CO-OPS readings of 88.3°F off Bay Waveland (station 8747437) and 86.7°F at Pascagoula Point (station 8741533) as of Sunday evening. The two-station spread of less than two degrees suggests warmth is fairly uniform across the Sound right now, not just isolated to one shoreline stretch. That warmth tracks with what Sport Fishing Mag's fall-transition coverage describes for Gulf snook right now: as days shorten, snook push toward their winter holding areas, and the outlet points to swimbaits like the Mulletron or Diezel MinnowZ working on aggressive fish during that shift. Anglers on the Pensacola Fishing Forum, just east along the coast, mention a redfish in a recent mixed catch, though that's a single, uncorroborated report rather than a confirmed pattern for the Sound.

What's next
The falling tide at Bay Waveland is due to bottom out near 6:34 PM local this evening, per station 8747437's prediction, with no fresh high posted yet in this update. Under a First Quarter moon, tidal swings stay moderate rather than the exaggerated ranges of a full or new moon, so current-driven bites should stay manageable rather than short and violent.
If the fall-transition pattern that Sport Fishing Mag describes for Gulf snook holds, expect that bite to keep building through the week as nights cool and baitfish start stacking up along drop-offs and passes. The outlet's broader fall-migration coverage this week flags the same seasonal cue more generally: as water cools, baitfish move toward the coast and draw predators with them, a pattern that lines up with the still-warm-but-easing readings here.
Water in the upper 80s at both stations means the transition is still early. Anglers planning around the evening low should look for moving water near structure in the hour on either side of that tide change, and weekend conditions should track closely with today's numbers barring a weather shift.
Context
Mid-to-late September in Mississippi Sound typically marks the start of the summer-to-fall handoff: water temperatures begin easing off their August peak and baitfish activity increases as fish push toward passes and channels. Readings in the upper 80s put this Sound on the warmer side of that curve for this point in the season, suggesting the shift toward cooler-water patterns is still a few weeks out rather than already underway. Anglers should check current Mississippi state regulations before harvesting, as seasonal rules can shift with this transition.
