Warm water holds redfish and snook in late-summer pattern
Mississippi Sound is running warm for late September, with NOAA CO-OPS stations 8747437 and 8741533 both posting water temperatures near 88°F this morning, more typical of high summer than the tail end of the month. That warmth is holding the Sound's fall transition species close to their summer pattern rather than pushing a hard seasonal shift. Sport Fishing Mag's look at Gulf snook this week describes fish still feeding aggressively before they eventually pull back toward winter holding water, a move that tends to follow falling water temperatures rather than the calendar. Inshore, Salt Strong's fall lure guide keeps redfish on its short list of targets as anglers size up bigger paddletails heading into the season, a sign the inshore bite is already leaning toward fall even with the water still summer-warm.

What's next
Expect water temperatures to hold in the mid-to-upper 80s over the next few days without a strong cool-down in sight, keeping the Sound closer to a late-summer pattern than an early-fall one. If nights keep cooling gradually, the shift Sport Fishing Mag describes in Gulf snook, feeding up hard before backing off toward winter holding areas, should start showing up in reports within the next couple of weeks rather than this week.
Redfish should stay the more reliable target through the transition; Salt Strong's fall lure lineup points toward bigger paddletails and swimbaits as the moves anglers are already making, worth carrying now rather than waiting on a hard cold front.
The waxing gibbous moon builds toward full over the next few days, which typically firms up low-light bites around dawn and dusk. Mississippi Sound's tides stay shallow and wind-driven this time of year, so plan around wind direction and the building moon rather than a single tide swing.
Context
Upper-80s water in Mississippi Sound this late in September runs on the warm side of normal for this stretch of the Gulf Coast, where the shift from summer to fall patterns typically starts once water slides into the upper 70s and low 80s. The Sound is still in its late-summer phase, with inshore species like redfish holding shallow structure and grass edges rather than staging for a fall push. Gulf snook run a similar late clock, typically holding a strong feeding pattern well into fall before dropping back to deeper winter refuges as temperatures fall further. A slower cool-down this year would likely push that whole transition later than a typical season.
