Fluke Bite Holds on Jersey Shore Reefs as Bonito Run Fills the Surf

What's biting

What's next

With Fishermans HQ LBI (NJ) already flagging 'hints of fall' in their August 29 report — cooler nights, lower humidity, and a growing showing of spearing, peanut bunker, and mullet in the bay — expect the next few days to keep building on that transitional feel. Bait moving into the back bays and along the surf typically pulls predators with it, and that's the pattern several NJ shops are already describing.

The fluke bite should stay serviceable through the near term but likely keeps trending toward more shorts mixed in with fewer keepers, similar to the pattern Capt Ron's Atlantic Highlands NJ described across a run of daily reports this week — solid action early in the stretch, tapering as it wore on. Anglers should expect to sort through a fair number of short fluke on reefs and wrecks, with the better keeper ratios likely holding on the outer structure per OTW Northern New Jersey.

The surf run of Spanish mackerel and bonito, per Grumpys Tackle (NJ) and The Fisherman — Central NJ, should keep building as warm water lingers along the beachfront — this is typical peak timing for those species, and shops are already stocking epoxy jigs and Deadly Dick spoons in anticipation of the pace picking up.

Several Northern NJ headboat captains are signaling the bigger seasonal shift worth watching for: once fluke fishing eases, expect more boats to pivot toward striped bass, per The Fisherman — Northern NJ. That transition typically accelerates as bait like sand eels stacks up along the beach and nearshore structure heading into September.

Offshore, the bluefin bite Fishermans HQ LBI (NJ) is working within 30 miles of Barnegat Inlet should hold as long as bait stays on the local grounds — trolling and live-lining squid are producing fish in the 25-40 lb class, with bonita mixed in on the same grounds.

With the holiday weekend on the calendar, expect boat traffic and fishing pressure to pick up on the fluke and sea bass grounds; anyone planning a weekend trip should watch dawn and dusk tide changes as the window when Spanish mackerel and bonito are most active through the inlets.

Context

Late August into early September is a well-known hinge point for Jersey Shore anglers: summer staples like fluke and sea bass are still producing but starting to fade, while the leading edge of the fall run — Spanish mackerel, bonito, and eventually striped bass — moves in through the surf and inlets. This year's reports line up with that typical calendar rather than reading as notably early or late. Grumpys Tackle (NJ) and The Fisherman — Central NJ describe the Spanish mackerel and bonito push as already underway in the back half of August, which is roughly on schedule for the region.

Several captains cited in The Fisherman — Northern NJ are explicitly framing this as a wait-for-stripers period — consistent with a normal season where the striped bass fall run doesn't meaningfully build along the Jersey Shore until water temperatures drop further into September and October.

NJ Fish & Wildlife News' recent feature on the Shark River Fishing Access WMA is a useful reminder of the species diversity typical around Jersey Shore inlet structure in-season — winter flounder, blowfish, tautog, bluefish, summer flounder, and striped bass are all named as species regularly taken there, which broadly matches the mixed-bag pattern showing up across this week's shop and captain reports.

There isn't a clear signal in this batch of reports comparing directly to prior years' timing, so beyond 'on-schedule for the calendar' we can't make a stronger claim than what's shown here.
