Sarasota tarpon season building as redfish and sharks heat up bay flats

What's biting

What's next

With Capt. Rick Grassett advising anglers to set up in travel lanes along the beach at first light, the next several days look favorable for tarpon. His June playbook per CB's Saltwater Outfitters: present live crabs, live baitfish, or DOA Baitbusters, give neighboring boats several hundred yards of buffer, and be ready for fish moving both north and south. Grassett specifically notes that schools push offshore to spawn near new and full moons; the first-quarter moon on June 23 puts us roughly a week out from the full moon, which should be a key window to watch for concentrated beach action transitioning to offshore staging.

On the inshore side, redfish should stay locked to oyster bar structure through the week. Capt. Chuck Cress of CB's Saltwater Outfitters found mullet jumping and heavy bait activity on an upper Sarasota Bay bar during his most recent charter — that surface bait concentration is one of the more reliable indicators that red drum are holding nearby. Early-morning and late-afternoon tidal pushes across shallow bar edges will be the most productive windows, as feeding fish follow moving water over structure.

Shark action needs no special setup beyond bait in the water. Capt. Brandon Naeve at CB's Saltwater Outfitters has been running consistent shark trips out of Siesta Key, with bull sharks, blacktips, and lemon sharks all active in Sarasota Bay and nearshore Gulf waters. That pattern typically runs through the fall months, so expect solid shark fishing well into the summer. Cut mullet or live bait fished near channel edges and bay grass flats should produce.

Snook are in their summer spawn window along the Gulf coast, making this one of the better times of year to hook a trophy fish near pass openings and beach structure. Harvest restrictions typically apply during this period on the Gulf coast — check current state regulations before keeping any snook and handle fish carefully to protect the breeding class. CB's Saltwater Outfitters documented strong snook activity at nearby Boca Grande earlier this season, suggesting healthy fish populations in the broader region.

No buoy or gauge data is available for this report, and Southwest Florida's late-June afternoon thunderstorm pattern can compress fishing windows quickly. Consult the NOAA marine forecast for Tampa Bay before launching and plan an early start to beat the typical afternoon build-up.

Context

Late June in Tampa Bay and Sarasota sits at the height of the tarpon season along Florida's Gulf coast. The silver king migration typically peaks from May through July in this region, with fish schooling along the beaches and staging near deep passes before heading offshore to spawn. Capt. Rick Grassett's June 2026 outlook via CB's Saltwater Outfitters describes schools as 'increasing in size and numbers' — a signal the run is tracking on schedule rather than running early or late.

Redfish and trout on shallow bay structure is a consistent late-June pattern for Sarasota Bay. The upper-bay oyster bar action Capt. Chuck Cress has been finding is expected this time of year, as baitfish like mullet cycle through the flats in higher numbers with the arrival of summer heat and red drum follow. The catch mix from recent outings — redfish, trout, occasional bluefish — mirrors the standard summer inshore composition this region is known for.

Shark activity in Sarasota Bay peaks from late spring through fall per CB's Saltwater Outfitters' captains, and this season is confirming that pattern. The presence of bull sharks, blacktips, and lemon sharks working the bay is not unusual for June; what it reflects is healthy forage density drawing predators into accessible water for anglers fishing out of Siesta Key.

One gap in this report's data picture is environmental readings: no buoy or gauge feeds returned current values, leaving water temperature and current flow unquantified. For Tampa Bay in late June, surface temperatures historically run in the upper 80s to near 90°F — a range that holds most species in predictable summer patterns. Anglers should pull real-time readings from the NOAA National Data Buoy Center before heading out, as temperature spikes or unusual tidal conditions can shift fish behavior meaningfully.
