August is deep summer in Sarasota — the snook closure continues through the month, but excellent fishing is available for redfish on the flats at dawn, tarpon at the Venice Inlet, Spanish mackerel nearshore, and flounder staging in the deeper channels. August fishing rewards the early riser who commits to first-light trips before the afternoon heat settles in.
Inshore Fishing — August
Redfish — Early Morning Only
August redfish fishing is strictly a first-light game. The combination of peak summer water temperatures and boat traffic makes mid-day flats fishing nearly unproductive. Commit to being on the water at sunrise or before — the Little Sarasota Bay shallows, the Casey Key outside edge, and the Stump Pass area at the southern end of the Sarasota market produce outstanding redfish action in the 30–60 minutes around sunrise. Gold spoons, 1/4 oz DOA Shrimp, and topwater plugs all work in this window. Fish go off by 9am.
Tarpon — Venice Inlet
August tarpon fishing at Venice Inlet is productive and significantly less pressured than the peak spring run. Resident tarpon move through the inlet on outgoing tides throughout summer — live mullet and large crabs on circle hooks produce consistent hook-ups from late afternoon through midnight. The Venice Fishing Pier also provides shore access to tarpon that feed under the pier lights at night.
Flounder — Building to Fall Run
Flounder numbers are building throughout August in the deeper cuts and channel edges of Little Sarasota Bay and Stump Pass. Live finger mullet or large Gulp! Grubs on a 3/8 oz jig head worked along the channel edges at 3–6 feet produces flounder that are staging ahead of the fall migration.

Summer Pattern Strategy
August in Sarasota is firmly in summer pattern territory. Water temperatures push 86–88°F surface and the inshore bite shuts down completely outside the dawn and dusk windows. On the water by 5:30 AM, off by 10:00 AM, back at 7:00 PM is the schedule. Bring extra water, sunblock, and watch the afternoon thunderstorms — they build fast over the bay and produce dangerous lightning.
Redfish on Flats Early
Redfish are the most reliable inshore target this month. Tailing fish are showing on the dark-bottom flats and around oyster bars at first light. Sight-casting with gold spoons, weedless soft plastics, or live shrimp on a popping cork all work. The flats of Roberts Bay, around the islands east of Siesta Key, and the back side of Lido all hold fish. By 9 AM the bite is over until evening.
Snook Closed, Tarpon Past Peak
Snook season is closed (catch-and-release only) through August 31. Fish are around — pass rocks at dawn, dock lights at night — but harvest is off. Use heavy gear, handle gently, get them back fast in the warm water. Tarpon are still in the system though numbers are smaller than May/June. New Pass on outgoing tide at dawn still produces shots at fish.
Trout and Mackerel
Spotted trout on grass flats at first light only — topwater plugs the first 45 minutes, then soft plastics. The grass flats off Stephens Point, Bird Key, and the back side of Lido are the productive water. Spanish mackerel are blitzing on bait pods along the beach and at the passes — Gotcha plugs on a wire leader. The kingfish bite at the inshore wrecks is firing — slow-trolled live pilchards on a stinger rig.
Offshore Builds
Federal red snapper season is open (verify NOAA dates). Inshore reefs in 80–120 feet stacked. Mahi-mahi on the offshore weedlines 20–30 miles out. Gag grouper, vermilion snapper, kingfish all available.
Conditions, Hotspots, Regs
Water 84–88°F. Florida saltwater license required. Federal reef fish endorsement (free). Tarpon over 40 release-only. Snook closed. Red snapper varies. Hotspots: New Pass dawn for tarpon, Roberts Bay flats at sunrise for reds, offshore wrecks at 80–120 ft for snapper. Best ramps: Centennial Park, Ken Thompson Park. Stay hydrated. Tight lines.
