Delaware Bay flounder bite heats up as keepers stack up in South Jersey

What's biting

What's next

Today's new moon is pushing tidal current toward its monthly peak, so expect stronger-moving water in the bay over the next several days. That should help, not hurt, the flounder bite Big Dave's Tackle and Higbee's Bait and Tackle are already calling accelerated — bigger swings on the incoming tide tend to push keeper flounder tight to structure, and the pattern Boulevard Bait & Tackle describes (working through shorts patiently to reach keepers on minnows and strip baits) should hold as long as the current stays strong.

The light wind and steady mid-70s water reported at buoy 44009 point to comfortable, stable conditions over the next 2-3 days, with nothing in the data suggesting a major wind event to disrupt the pattern. If that mild wind holds, the croaker push flagged by both Higbee's Bait and Tackle and Smith's Bait Shop should keep building — croaker and spot numbers typically swell through the bay's reef sites and oyster beds once water settles into the low-to-mid 70s.

Sea bass action on the ocean wrecks just outside the bay, described by Big Dave's Tackle as stacked up with keeper-size fish, should stay productive into the weekend since reef and wreck structure tends to hold fish through stable summer temperatures. As always, check current NJ size and possession limits before keeping anything.

Further out, Eric Burnley's Delaware, Maryland & Chesapeake Bay report notes yellowfin tuna and tilefish coming from the canyons on trips that also produced bay species, suggesting boats making that run are finding a worthwhile mixed bag when weather allows.

Plan around the new moon's stronger tide swings for the next few days — set drift or anchor timing to the moving water rather than fighting slack tide, especially for flounder. Burnley's read that 'there is no reason why this good fishing in Delaware Bay and the ocean on out to the canyons should not continue into July' is the clearest forward signal in this week's reports. Bloodworms, Fishbites and peeler crab on hi-lo rigs remain the standard for croaker and spot around the oyster beds and reef sites, while minnows and Gulp or strip baits keep producing on the flounder side.

Context

Mid-July flounder action of this caliber tracks the typical seasonal window for Delaware Bay's NJ side — the bay's warm, shallow flats generally peak for summer flounder from late June through August as fish move onto flats and reef sites to feed, and Big Dave's Tackle's 'accelerated' bite with 20-to-22-inch keepers fits that window rather than running notably early or late.

The croaker push described by Higbee's Bait and Tackle and Smith's Bait Shop is also typical mid-summer behavior — croaker and spot move into the bay's oyster beds and reef structure as water warms into the low-to-mid 70s, consistent with the 74°F reading at buoy 44009.

Eric Burnley's Delaware, Maryland & Chesapeake Bay column offers the clearest season-over-season read in this data: June's croaker, spot, sheepshead, bluefin tuna and flounder numbers were called the best 'we had all year,' with an expectation the pattern carries into July. No source in this feed flags a slowdown or a below-average start, so the pattern here reads as on-schedule to slightly ahead of a typical mid-summer pace for the bay's core flatfish and panfish species.

There isn't enough year-over-year data in this feed to say definitively how this July compares numerically to past seasons — the sources describe conditions as strong relative to the season's usual arc, but don't provide a direct historical benchmark.
