Redfish stir along the Louisiana Gulf as delta waters stay summer-warm
Water temperatures at the Grand Isle and lower Mississippi River pass tide stations are still running full summer-warm, 85.8°F and 86.2°F this morning, even with fall underway on the calendar. Coastal Angler Magazine's latest reader catch reports include a solid Redfish, a 22-inch red drum boated in nearby Gulf waters, a sign the species is active and catchable heading into October. Southwest Louisiana's Calcasieu Estuary remains one of the region's marquee inshore fisheries year-round, per Sport Fishing Mag.

Both tide stations show their next low arriving late morning, 11:34 a.m. CDT at Grand Isle and 10:42 a.m. CDT at the lower delta pass station, so working the last stretch of the outgoing tide into early afternoon should concentrate bait and Redfish along channel edges and marsh drains through midweek.
The moon is waning toward new, so tidal swings should ease slightly over the next few days before building again as the new moon approaches, worth planning around for a weekend trip.
Water this warm typically holds until day length and passing fronts start pulling it down, so Redfish should stay a reliable target through early October before deeper fall patterns take over.
Context
Late September in the Gulf Coast and Delta region sits at the hinge between summer and fall fishing. Inshore waters are still running warm, and the shift toward classic autumn marsh patterns typically builds through October as cold fronts start moving through. Redfish activity picking up now is on schedule for the season, not early or late.
