Delaware Bay flounder limits stack up as croakers flood the flats

What's biting

What's next

With no fresh buoy or gauge readings in hand today, we're leaning on this week's shop and captain reports to read where the bite is headed. The flounder bite building on the Old Grounds and the TI and Wildwood Reefs, per Big Dave's Tackle and Boulevard Bait and Tackle, shows no sign of slowing — deepwater structure has consistently outproduced shallower nearshore spots, and that pattern should hold into the coming days with water still warm through late August. Anglers working the deepest sections of these reef sites with large Gulp Mullets, minnows, spearing and strip baits are seeing the best keeper ratios, and that presentation edge should keep paying off heading into the weekend.

In the back bays, Higbee's Bait and Tackle reports flounder nearing the 23-inch mark alongside a summer mix of blues, spot, croakers and black drum — a sign the bay is still holding a broad, healthy forage base this late in the season. Croaker numbers, described as thick enough to light up a fishfinder by Hands Too Bait and Tackle, should keep building over the next couple of weeks as water stays warm; expect that action to remain a reliable fallback when the flounder bite slows.

On the surf side, Boulevard Bait and Tackle's 8th Street jetty report of triggerfish and tog mixing in, with Spanish mackerel expected to arrive, is worth watching — mackerel typically filter into South Jersey inlets and jetty structure as late summer peaks, so anglers working cut squid and crab around structure should start seeing more of that mix show up over the next week or two.

Tide timing matters most right now: incoming tide has generally favored flounder in the back bay channels, while croaker and spot action has leaned toward deeper channels on the push, per reports across The Fisherman's Southern New Jersey and Surf desks. With the waxing gibbous moon building toward full, expect stronger tidal swings over the next several days, which should concentrate bait and predators around structure at the peak of each tide change — plan trips around those windows rather than the slack middle of the tide. As always, confirm current size and possession limits before keeping any fish, since regulations can shift seasonally (per NJ Saltwater Fisherman).

Context

Delaware Bay's late-August pattern this year reads as fairly typical for the region: a strong flounder bite concentrated on deepwater reef and wreck structure, a thick croaker push filling the back bays, and an occasional black drum or weakfish rounding out the mix. Higbee's Bait and Tackle's description of croakers 'just starting to approach eating size' suggests this year's croaker class is running on a normal late-summer schedule rather than notably early or late.

The broader Northeast picture, per The Fisherman (Northeast)'s NJ/DE Bay Region forecast published earlier this week, frames the stretch heading toward Labor Day as a transition period — inshore and surf species remain the focus before attention shifts toward fall migrations. That lines up with what the Delaware Bay shops are describing: solid, unspectacular flounder and croaker action rather than the blitz-style fishing associated with the fall run, which is still weeks out for this region.

We don't have direct year-over-year comparison data in this feed set, so it's worth being honest about the limits of this read: none of the sources here explicitly frame this season as ahead of, behind, or on pace with prior years. What can be said is that the mix of species being reported — flounder, croaker, spot, black drum, blues — is the standard late-summer Delaware Bay lineup, with nothing flagging an unusual absence or an early arrival that wouldn't normally be expected this time of year.
