Sea Bass Loaded, Fluke a Grind Around Sandy Hook

What's biting

What's next

With the moon waxing toward full, tidal currents should strengthen over the next several days, which typically sharpens the bite window for structure-oriented species like sea bass and tog around the Highlands jetties and bridge pilings — worth timing trips around the stronger pushes rather than the slack.

Multiple Northern New Jersey captains reporting out of the Belmar/Highlands corridor describe the season as running late, with several — including Capt. Al Shinn of the Miss Belmar Princess and Capt. Nick Caruso of the Ol' Salty II — expecting a strong September as fluke season winds down. Capt. Shinn told The Fisherman he plans to switch over to striped bass once fluke season closes, if the stripers show up on schedule. Capt. Rich Falcon of the Golden Eagle reports bluefish mixed with bonito, albacore, and Spanish mackerel through the back half of August, and flagged sand eel abundance as the wildcard that could make or break the September bite.

If that pattern holds for Sandy Hook and Raritan Bay proper, expect the current sea-bass-heavy, fluke-stingy mix to persist over the next few days, with bonito and Spanish mackerel action building on the outside beaches and around the inlet mouth as bait continues to stage. The fluke bite should firm up on the stronger tide stages even if it stays a sort-through-the-shorts grind overall — Capt. Ron's recent reports suggest power-drifting is outproducing anchoring right now.

The bigger shift to watch for is the striped bass turn. None of this week's Sandy Hook-area sources report stripers actively biting yet, but the Northern NJ captain network is explicitly bracing for it as fluke season closes out and water starts to cool. Anglers planning trips into early September should have both fluke and striper gear rigged, since several captains expect a fast transition once it starts. Keep an eye on sand eel concentrations near the inlet — shops tracking Central NJ waters are already noting heavy sand eel presence nearby, which tends to be the trigger for both the fall striper push and improved fluke and bluefish action as predators key in on the bait balls.

Context

Late August in Raritan Bay and around Sandy Hook is typically a transitional stretch — the summer flounder run is winding toward its close, black sea bass fill in as the dependable bycatch, and the first signs of the fall migration (sand eels, an early bonito and Spanish mackerel push) start showing up in the surf and at the inlet. This week's reports track that pattern closely. Several Northern New Jersey captains, including those running out of Belmar and the Highlands corridor, describe 2026 as a "late" season overall, with the better fluke fishing not really finding its groove until August — which lines up with Capt. Ron's continued fluke frustration this late in the month rather than a typical late-July peak.

The striped bass turn that usually anchors the fall run hasn't shown up yet in any of this week's Sandy Hook-area sources, though multiple captains are explicitly planning around it, suggesting it's expected on a normal-to-slightly-delayed timeline rather than early. The presence of Spanish mackerel, bonito, and building sand eel numbers is a fairly standard late-August signal for this stretch of coast and is being reported as on-schedule rather than early or late by the shops tracking it.

No buoy or gauge data was available for this report, so water temperature and tidal flow context can't be compared numerically against seasonal norms — that comparison will need to wait for a cycle with live readings.
