The last week of August is the hinge of the Stuart season. Water is still bathtub warm, afternoon storms are stacking up over the interior every day, and the first ragged schools of finger mullet are showing along the beaches south of the St. Lucie Inlet. Nothing has turned on all at once yet, but the pieces are moving into place and the fish know it before we do.
What’s Hitting
Snook are the headline. Slot and over-slot fish are stacked in the inlet and on the bridge shadow lines after dark, and the better bite has been on the last of the outgoing when bait gets flushed out. Mangrove snapper remain thick on the inlet rocks, the Crossroads channel edges and the artificial reefs — steady 12 to 15 inch fish with a few better ones mixed in.
Tarpon are around in juvenile-to-mid sizes in the river and along the beach, keying on the early mullet. Big jacks are doing the same and will wreck a light outfit. Speckled trout and slot redfish are holding in the south end of the Indian River Lagoon on cooler mornings, and a scattering of Spanish mackerel is working the inlet mouth on clean incoming water.
Where to Find Them
The St. Lucie Inlet and the Crossroads — where the St. Lucie River, the Indian River Lagoon and the inlet all meet — is the engine of everything right now. Fish the rock jetties and the channel edges either side of the tide change. The Roosevelt and Evans Crary bridges hold snook on the down-current side of the pilings after dark.
In the South Fork, Bessey Creek and the Halpatiokee stretch, the story is snook, small tarpon and juvenile jacks tucked under overhanging mangroves and around downed timber. Beach anglers should walk south from the inlet at first light and look for nervous water — the early mullet knots are small but they are already dragging predators behind them.
Tides & Conditions
Tides this week run a moderate range with the strongest water movement around the new moon period. Prioritize the two hours either side of the tide change rather than fishing a slack inlet. Water temps are sitting in the mid to upper 80s inshore, which pins the best action into the first two hours of daylight and the hours after dark.
Storms are the real variable. Afternoon cells have been dumping fresh water into the North and South Forks, which pushes the salinity line east and stacks bait — and predators — at the mouths of the creeks a day or two after a heavy rain. Expect stained water up the forks and cleaner conditions from the Crossroads out.
Tackle & Tactics
For inlet and bridge snook, a 7-foot to 7-foot-6 medium-heavy spinning outfit with 30-pound braid and 40- to 50-pound fluorocarbon leader is the workhorse. Live croakers, pilchards and finger mullet are hard to beat; on artificials, a white or olive paddletail on a half-ounce jighead swum across the light line will get eaten.
Mangrove snapper demand a lighter touch — 20-pound braid, 25-pound fluoro, a small circle hook and a live shrimp or cut sardine drifted along the rocks. Downsize the leader before you downsize your expectations. For beach tarpon and jacks, a 4/0 to 5/0 circle on a live mullet under a float, or a big topwater walked through the bait pods at daybreak.
Local Intel This Week
Public access is straightforward here. The Sandsprit Park ramp on Manatee Pocket puts you minutes from the Crossroads and the inlet. Leighton Park in Palm City is the practical launch for the South Fork and Bessey Creek. Phipps Park and the Stuart Causeway ramp cover the North Fork and the middle river. Shore anglers can work the Stuart Causeway catwalks and the jetty at Hutchinson Island.
Fish are concentrating hardest at the inlet mouth and along the first mile of beach south of it as the mullet trickle in. Snook and tarpon regulations in this region change by season and by coast — check current FWC regulations and open seasons before keeping any fish, and handle released snook and tarpon in the water when you can.
This Week’s Tip
Do not chase the biggest mullet school you see. The early-season schools are small and skittish, and a boat that runs up on them scatters the whole thing. Instead, get upcurrent of a pod, kill the motor, and let the bait drift to you. The predators are usually working the trailing edge and the bottom of the school, not the middle — put your bait behind and under, not on top.
