Redfish and snook turn on as Mobile Bay holds late-summer warmth
Water temperatures are holding summer-warm across lower Mobile Bay and the Gulf approaches, with NOAA's Dauphin Island station (8735180) reading 88°F and the inner-bay station (8736897) close behind at 87.8°F as of early Monday morning. That warmth is keeping the fall transition on a slow burn rather than a hard turn. Sport Fishing Mag notes Gulf snook anglers are seeing the seasonal shift kick in as days shorten, with fish feeding up before pushing toward their winter holding areas. Salt Strong's fall lure rundown lists redfish and snook among the inshore targets worth working right now, pointing anglers toward swimbaits and paddletails as water starts to cool. Neither source names a specific stretch of coast, so treat this as the regional pattern rather than a hot local bite — but with water still near 88°F, that transition has plenty of runway left before it forces fish out of their summer haunts.

What's next
Expect water temperatures to hold in the upper 80s through midweek. Nothing in the current readings points to a fast cooldown, so redfish and snook should keep behaving like it's still summer rather than snapping into a true fall pattern just yet. The tide swing at Dauphin Island (8735180) brings a high near 7:15 AM CDT and a low around 6:38 PM CDT, with the inner-bay station (8736897) close behind on its high around 8:44 AM CDT — mornings on the outgoing push into the afternoon low are worth building a trip around for current-dependent structure. The Waxing Gibbous moon adds extra tidal push heading into the weekend, which should sharpen activity around both tide changes. If the fall pattern Salt Strong and Sport Fishing Mag describe holds, redfish and snook activity on swimbaits and paddletails should build through the week as shorter days nudge fish toward their seasonal shift, even with water temps still running warm.
Context
Water in the upper 80s is typical for Mobile Bay and the northern Gulf in late September. This region's fall transition typically runs later and softer than the Northeast or mid-Atlantic, with inshore species like redfish and snook staying in a summer-leaning pattern well into October before water temps force a real shift. Late September is generally when anglers start watching for that changeover rather than seeing it fully arrive, so current conditions read as on schedule for this time of year rather than early or late.
