Fishing in July — Sebastian, Florida

In July, Sebastian Inlet gives up catch-and-release snook, newly arriving mangrove snapper, Spanish mackerel, big jack crevalle on mullet schools, lookdowns, barracuda and passing tarpon, with whiting and pompano in the surf when the water is clean.

The July reports from the Sebastian Inlet District read like the start of summer fishing. For the week of July 6, 2026, the district's guide wrote that the water had cleaned up nicely and warmed to the seasonal 84 to 85 degrees, with greenies around the jetty, tiny mojarra at the T-Dock and schools of mullet in the inlet drawing big jack crevalle and huge redfish. Two weeks later, on July 20, 2026, he reported that fish were beginning to arrive and bite on both sides of Sebastian Inlet, with greenies, mojarra and late afternoon mullet schools all plentiful.

Snook dominate the July action even though none may be kept. On the north jetty in the week of July 20, 2026, many catch-and-release snook came on live shrimp, croakers, mojarra and artificial shrimp jigs during the incoming tide, and the guide described a day of large fish in the 18 to 22 pound range. The mangrove snapper is the fish that changes the month: the same reports call it, along with Spanish mackerel, a summertime staple of the inlet.

Ocean water near Sebastian averages about 83 degrees in July by NOAA's nearest coastal records, though upwelling can drop the inlet into the mid 70s for days at a time.

The NOAA National Centers for Environmental Information coastal water temperature guide gives a July average of 83.2 degrees at Trident Pier in Port Canaveral and 82.9 degrees at the Canaveral buoy 20 nautical miles offshore, the closest long-record stations to Sebastian Inlet. Those averages match the 84 to 85 degrees the district reported on July 6, 2026, and the 81 to 84 degrees on July 20, 2026.

July 2025 showed how fast that can change. For the week of July 14, 2025, the district reported that the water had again gone down into the mid 70s, with 75 degrees seen over the weekend, and that the cold water had the fish in lockjaw mode. Even so, the north jetty water was clear enough to watch snook, redfish and jacks swimming around the pilings, while goliath groupers harassed the snook. July also falls inside the Atlantic hurricane season, which the National Hurricane Center dates from June 1 to November 30, and the July forecasts printed in the reports all called for afternoon thunderstorms.

In July the north jetty produces snook, mangrove snapper, Spanish mackerel and lookdowns, the wall to the bait shop holds big jacks on mullet, and the T-Dock yields snapper, small sheepshead and whiting.

On the north jetty, the July 6, 2026, report found decent mangrove snapper finally showing in the pilings on small live shrimp and greenies, lookdowns biting tiny hair jigs at the tip on the incoming tide, and black margates and spot tail pinfish on cut shrimp. Along the wall between the jetty and the bait shop, anglers freelining live mullet caught big jack crevalle in the channel and mangrove snapper of 14 to 16 inches on the higher incoming water.

The July 20, 2026, report added Spanish mackerel of 16 to 18 inches on live greenies and spoons on the beach side of the north jetty, and a 47-inch barracuda that hit a silver spoon meant for mackerel. Near the cleaning table, late afternoon mullet schools drew monster jack crevalle of 15 to 25 pounds, and the guide reminded readers that mangrove snapper have to be a minimum of 10 inches with a bag of 5 per person.

At the T-Dock in July 2026, the open part of the dock produced small sheepshead, mangrove snapper, lane snapper and whiting on cut shrimp, either tide. In July 2025 the rebuilt north jetty walkway had just reopened: the July 1, 2025 report counted about 150 people or more at the jetty on June 30, with lookdowns on fire for anglers using live greenies and tiny crappie jigs. The same report found small mangrove snapper starting to show around the T-Dock pilings as the water kept warming.

Goliath groupers are the July tax at the Sebastian Inlet north jetty. On reopening day in 2025 only two snook were hooked and the groupers ate both of them, so the guide asked anglers not to target snook during the summer spawn. Bluefish of 15 to 16 inches came instead to silver spoons and vertical jigs cast out far.

July surf fishing near Sebastian Inlet depends on bait schools and water depth, and rain runoff from the Sebastian River can shut down the outgoing tide at the inlet.

The beaches beside the inlet were hard to fish in July 2026. The July 6, 2026, report described a huge sandbar running from the north jetty about half a mile up the beach, leaving only two to three feet of water, and said bridge construction had limited access to the south side beach. By July 20, 2026, the south jetty could be reached only by a walk of about seven tenths of a mile from the south day use area, where black margate, small sheepshead, whiting and a few nice mangrove snapper were biting on cut shrimp.

In clean surf, July brings bait. The July 14, 2025, report said mullet and glass minnows were moving down the north beach and that the guide had seen king mackerel and cobia taken from the beach around Sebastian Inlet when the mullet run, along with big redfish, jacks, tarpon and sharks. Anglers on shrimp and sandfleas caught whiting, croakers and black drum on the high tide phases.

Fresh water is the July spoiler. On July 20, 2026, the district blamed tannin-stained Intracoastal water from rain runoff coming out of the Sebastian River for slowing the outgoing tide at the north jetty. The July 1, 2025 report found the north side surf silted up with no anglers fishing it at all.

In July, snook are closed to harvest in the Indian River Lagoon region, redfish are catch-and-release only there, and any tarpon over 40 inches must stay in the water.

FWC's snook regulations for the Indian River Lagoon region, which runs from New Smyrna Beach to the Martin and Palm Beach county line and includes Sebastian, set closed seasons of December 15 to January 31 and June 1 to August 31, with a slot of 28 to 32 inches and one fish per person when open. The FWC red drum rules list the same region as catch-and-release only for redfish year-round. For tarpon, FWC's tarpon page calls the fishery catch-and-release only and says tarpon over 40 inches must remain in the water, which applies to the tarpon that pass the Sebastian Inlet jetties and beaches in summer.

July is a month of light tackle and live bait at Sebastian Inlet: small hair jigs for lookdowns, spoons for mackerel, and live greenies, shrimp and mojarra for snapper and snook.
