Late August around Fort Myers and Sanibel is wet-season fishing in its purest form. The Caloosahatchee is pushing a lot of fresh water into the sound, the passes are moving hard on the tides, and the fish have sorted themselves along the salinity line. Once you learn to read that line, the pattern is remarkably consistent day to day.
What’s Hitting
Mangrove snapper are the most reliable target in the region right now, stacked on the bridge pilings, the pass rocks, the dock lines and the nearshore hard bottom.
Snook are on the beaches of Sanibel, Captiva and Bonita at first light, and in Blind Pass, Redfish Pass and Captiva Pass on the outgoing tide. Redfish are in the backwater on the mangrove edges and oyster bars. Speckled trout are on the deeper grass in Pine Island Sound early. Nearshore, Spanish mackerel and a few late tarpon are around the passes and the beach bars.
Where to Find Them
The passes — Blind Pass, Redfish Pass, Captiva Pass and Boca Grande to the north — are the snook and snapper highways. Fish the rocks and channel edges on moving water.
In Pine Island Sound and Matlacha Pass, work the mangrove points, oyster bars and creek mouths on the higher tide stages for redfish and juvenile snook. Trout hold on the deeper grass in three to six feet. The Sanibel Causeway bridges and the pilings under the Matlacha bridge are dependable mangrove snapper spots. Watch the salinity edge in the Caloosahatchee — it moves with the rain and the fish follow it.
Tides & Conditions
Water temps are in the upper 80s inshore. Wet-season runoff has the upper Caloosahatchee stained and fresh, and heavy release weeks push that stain well down toward the sound.
Tides are moderate this week. The passes fish best on the last of the outgoing, when bait is flushed out of the back. The beach fishes best in the first hour of daylight before the sun gets high and the water traffic starts. Afternoon storms are a daily event; start early and plan to be off the water by early afternoon.
Tackle & Tactics
For mangrove snapper, light tackle is not optional: 20-pound braid, 20- to 25-pound fluorocarbon leader, a No. 1 or 1/0 hook and a small live shrimp fished tight to the pilings. Heavy leader in this clear water is why most anglers do not catch them.
Snook on the beach want a small white paddletail or a live scaled sardine on a 2/0 to 3/0 circle, cast parallel to the wash rather than out to sea. In the passes, step up to 30-pound braid and a 40-pound leader with a heavier jighead. Backwater reds eat a weedless soft plastic or a cut ladyfish chunk on a light Carolina rig.
Local Intel This Week
Ramps and access: the Punta Rassa ramp at the Sanibel Causeway, the Matlacha Park ramp, the Pine Island ramp at Bokeelia, and the Imperial River and Bonita Beach ramps to the south. Shore anglers can fish the Sanibel Causeway islands and the Sanibel fishing pier.
Fish are concentrating along the salinity edge and in the passes on moving water, with the beach best at dawn. Snook and redfish in this region have been under adjusted rules since the red tide events of recent years — check current FWC regulations and open seasons for the Southwest Florida management zone before keeping any fish.
This Week’s Tip
If you are getting picked clean by mangrove snapper without hooking up, the problem is almost always your leader, not your hook. Drop from 30-pound fluorocarbon to 20, then to 15 if you have to. It feels reckless around barnacle-covered pilings, but three hookups on light leader beats twenty bait-stealing taps on heavy leader every single time.
