Fluke and sea bass hold strong as bonito push into the surf off Sandy Hook

What's biting

What's next

With the moon past full and easing toward its Last Quarter phase, expect tidal swings to moderate over the next few days before current strength builds again heading into the new moon — worth timing longer soak times and slower-moving baits around the slack accordingly.

The bigger story locally is the seasonal handoff already visible up and down the Jersey Shore. Grumpys Tackle notes that warm water has pushed Spanish mackerel and bonito into the mix alongside the standing fluke bite, and OTW's Northern New Jersey report confirms bonito and Spanish mackerel are showing in the surf and inlets to the north — both species that typically push into Raritan Bay and around Sandy Hook as late-summer water holds warm, so anglers working the surf and inlet edges with small metals and epoxy jigs should expect a shot at them in the coming days if the pattern holds.

Fluke fishing should stay the most reliable target through the week. Capt Ron's put together one of the stronger fluke days of the stretch on the reefs and structure it has been working, and The Fisherman's Northern New Jersey edition has keeper fluke holding on reefs and wrecks even while the offshore tuna bite stays spotty — that combination (solid inshore structure bite, inconsistent offshore) is a pattern that tends to hold until water temps break sharply, so there's no strong signal yet that the fluke window is closing.

Sea bass should continue filling out mixed-bag trips; Blue Chip Sportfishing and Capt Ron's both describe sea bass crowding the bottom hard enough to intercept baits meant for fluke, which is a good sign for anyone bottom-fishing structure through the weekend.

Longer range, keep an eye on the classic late-summer-into-fall turnover: as nights cool through September, expect bluefish and the first signs of migrating striped bass to build in the surf and back bay, following the bait pushes that shops up and down the coast are starting to flag. Nothing in this week's reports confirms that shift has started in Raritan Bay specifically, so treat it as the seasonal setup rather than a live bite yet. No fresh buoy or gauge telemetry came through this cycle, so cross-check wind and sea-state against a live marine forecast before planning an inlet or ocean-side trip.

Context

Early September is peak transition season for Raritan Bay and Sandy Hook, and this week's reports read as right on the seasonal calendar rather than early or late. Fluke fishing holding strong into the first days of September — as Capt Ron's and The Fisherman's Northern New Jersey edition both describe — is typical; the summer flounder season traditionally runs into early autumn along this stretch of the Jersey Shore, and NJ Fish & Wildlife News is actively soliciting angler data through its Summer Flounder & Black Sea Bass Tally Form specifically because that fishery stays active this late in the year.

The Spanish mackerel and bonito showing up in the surf, as flagged by Grumpys Tackle and OTW's Northern New Jersey report, also lines up with the normal late-summer warm-water push these fast-moving species make along the mid-Atlantic coast before the fall cooldown sends them back south — a reliable, recurring pattern rather than anything unusual for this date.

One regulatory thread worth tracking rather than fishing: NJ Fish & Wildlife News reports hearings are scheduled on a draft addendum that could cut the Chesapeake Bay menhaden reduction-fishery cap by up to half. Menhaden are the forage base much of this bay's bluefish, striped bass, and bonito activity depends on, so the outcome is a longer-term watch item, not something that changes conditions this week.

No striped bass activity was reported in this batch of Raritan Bay-area intel, which isn't unusual for early September — the more typical bass push into this specific area tends to build through the fall run rather than late summer, so its absence here doesn't read as a red flag.
