Late Summer Transition Bite Heats Up in the Louisiana Marsh and Beyond

Artificial Lure here with your fresh-off-the-water fishing report for the Gulf of Mexico and New Orleans area, Saturday, September 13th, 2025. We're kicking off the day with a classic late-summer pattern, and fall transition action is heating up from Delacroix marsh to the rigs south of Grand Isle. According to Louisiana Sportsman, September’s a transition month—specks and redfish are on the move, chased by cooler nights and the first hints of bait migration. Capt. Sean Thornton out of Delacroix reports solid numbers of mixed-size speckled trout, with keeper reds mixing in just outside the grass lines and in deeper passes. Let's get into the details. Today’s sunrise was at 6:39 a.m., with sunset on deck for 7:15 p.m. That gives us over twelve and a half hours of daylight—plenty of time to wet a line. Tides are running strong: Tides4Fishing says we’re looking at a high tidal coefficient, starting at 77 this morning and pushing up to 90 by evening, which means plenty of water movement and active fish, especially on the outgoing tide late morning and around dusk. Weatherwise, it’s classic southern Louisiana—mid-80s by afternoon, humidity making it feel just a notch stickier. Winds are steady southeast at 8-12 knots. No storms brewing but keep an eye out for fast-moving showers, especially late afternoon. Now, onto the bite. This week, anglers are pulling in solid speckled trout—sizes ranging from 14 to 21 inches—with a few heavies over 24 inches reported off Bayou Bienvenue and near the MRGO rocks. Redfish action is lively, with both slot reds (16–27 inches) and a handful of rampaging bulls, especially around the deeper cuts and outer bays. Near Grand Isle, there's even talk of big jacks chasing mullet along the beaches, and the sheepshead bite has been a surprise bonus for some dock and rig hoppers. Best baits and lures right now? For trout, you can’t go wrong with live shrimp under a popping cork, but artificial fans are doing just as well working Matrix Shad or Vudu shrimp in the Limbo Slice and Opening Night patterns. Topwater baits like Rapala Skitterwalks at sunrise are nailing aggressive fish in the shallows, especially on calmer mornings. For reds, gold spoons and soft-plastic paddle tails in green or root beer colors have been hot. Bull reds offshore? Try cut mullet or live pogies on a Carolina rig. If you’re looking for absolute hot spots, circle Delacroix Point and Shell Beach as your inshore targets—these marshy edges are full of life. Offshore, the Four Bayous and near the Grand Isle bridges are producing consistent action, especially an hour before and after tide changes. One notable catch this week comes from Maurice Terrebonne, who hauled in a monster speckled trout off Elmer’s Island on a Carolina rigged live pogie—solid proof live bait’s always in style. A reminder for the weekenders: the shrimpers in southwest Louisiana are noticing smaller hauls, partly blaming industrial activity according to News from the States, but th This content was created in partnership and with the help of Artificial Intelligence AI.
