This week on the Treasure Coast the calendar finally starts working in our favor. Water inside the river is still in the upper 80s and the afternoon storm line still builds over the interior by two o’clock, but the first ragged pods of finger mullet have shown along the beach north of the inlet. That is the tell every Stuart angler waits on in late August — the fish know it before we do.
What’s Hitting
Mangrove snapper are still the most dependable fish in the system, packed on the inlet jetty rock, the causeway rubble and the Roosevelt Bridge pilings. Snook are eating hard on moving water at night; Atlantic-coast harvest remains closed for a few more days, so plan on catch-and-release and handle fish in the water. Tarpon are along the beach at first light and inside the inlet on night tides, mostly 20- to 70-pound fish. Offshore, mahi are scattered on weedlines in 120 to 250 feet and kingfish are back on the nearshore reefs following the bait.
Where to Find Them
The St. Lucie Inlet rocks and the Sailfish Flats edge remain the two highest-percentage zones. Work the beach from Peck Lake north to the inlet at gray light and look for nervous water rather than rolling fish — the early mullet are small and the predators under them are subtle. Inside, the Roosevelt and Evans Crary bridge lights hold snook and snapper after dark. The South Fork and Bessey’s Creek are fresher after the rain, pushing juvenile snook and tarpon toward the creek mouths.
Tides & Conditions
We are working off a waxing moon into the first quarter, so tides are moderating from last week’s springs — less brutal current through the inlet and a longer usable window on either side of the change. Inshore water 86 to 89 degrees, low 80s offshore. Storms fire between 2 and 5 p.m. most afternoons. Nearshore visibility is good on the incoming and stained on the outgo after a heavy rain day.
Tackle & Tactics
A 3000- to 4000-size spinning reel with 20- to 30-pound braid and 30- to 40-pound fluorocarbon handles nearly all the inshore work. Live pilchards, croakers and mullet are the best bridge snook baits after dark; a three-quarter-ounce flair hawk swum slowly across the shadow line is the reliable artificial. For snapper, drop to 15-pound fluorocarbon and a small live shrimp on a 1/0 hook — the light leader genuinely matters in clear water. On the beach, keep a 4000-size rod rigged with a swimbait that matches a four-inch mullet.
Local Intel This Week
Sandsprit Park is the workhorse inlet ramp and is full by 7 a.m. on weekends. Leighton Park in Palm City and Phipps Park put you on the South Fork fast and stay far quieter. Shore anglers are taking snapper and the occasional snook off the Stuart Causeway catwalks after dark. Fish are concentrating on structure and moving water rather than spreading across open flats. Check current FWC regulations and seasons before keeping any fish.
This Week’s Tip
When you find the first mullet pods, resist casting into the middle of them. Work the trailing edge and the down-current corner. Predators sit behind and below the pod picking off stragglers, and a lure that swims out of open water into the school looks like the one fish that got separated.
