Delaware Bay flounder and sheepshead heat up on the NJ side

What's biting

What's next

Over the next two to three days, expect the current mixed-bag pattern on Delaware Bay's NJ side to mostly hold, with one weather caveat: Eric Burnley's report in The Fisherman — DE/MD/Chesapeake notes rain and thunderstorms in the forecast for the broader bay region this week. A hard blow can muddy nearshore water and put flounder, sheepshead, and other sight-feeding species off the bite for a tide or two, while croaker and black drum, which tolerate turbid water better, should keep producing through any weather.

The keeper flounder bite that Big Dave's Tackle is seeing on the nearshore and offshore reefs, per The Fisherman — Southern NJ, should keep building through early August as fish continue their typical late-summer push toward structure. Anglers working ocean-adjacent reef sites are likely to keep out-fishing the back bays, where the short-to-keeper ratio remains poor according to the same report. Sheepshead should stay active around back-bay structure in the calmer windows between any storm systems.

Croaker fishing along Fortescue Beach on blood or lung worms, as reported by Higbee's Bait and Tackle (also The Fisherman — Southern NJ), is a reliable option through this stretch and should remain a bay-wide staple into mid-August. Kingfish and spot should keep mixing in with croaker on the same baits. The white perch bite in the tidal creeks, also noted by Higbee's, is worth checking for anglers wanting a change of pace from bay-structure fishing.

With a Last Quarter moon this week, tidal swings run moderate rather than extreme, generally a favorable window for working structure and channel edges without fighting the strongest current of the month. Anglers planning a weekend trip should aim for the calmer days around any midweek rain, since disturbed water tends to shut down flounder and sheepshead faster than it affects croaker or black drum.

Watch for weakfish numbers to hold steady rather than surge — the pool-winning fish reported by Higbee's ran modest, around 3 pounds, consistent with a mixed rather than blown-out weakfish season on the bay so far this year. Black drum should continue showing up as a bonus catch around bay structure, with the 15-pound pool winner from Higbee's a sign the bigger fish are still around.

Context

Early August on Delaware Bay's NJ side is squarely within the traditional summer pattern for this fishery: flounder shift toward ocean reefs and channel structure as back-bay water warms and holds more short fish than keepers, croaker and spot flood the bay beaches, and sheepshead and black drum show up around structure. Nothing in this week's reports from The Fisherman — Southern NJ reads as unusually early or late for the calendar — the mixed-bag variety described by Higbee's Bait and Tackle (blues, croaker, weakfish, flounder, sheepshead, and occasional black drum) and the keeper-flounder-on-reefs pattern from Big Dave's Tackle both track with what this bay typically produces in the first week of August.

One point worth flagging for the season overall: the pool-winning weakfish reported at 3 pounds is on the modest side for a bay that has historically also produced larger fish in some years, though a single pool winner isn't enough signal to call the weakfish run under- or over-performing. Similarly, the back-bay flounder fishery running mostly short (per Big Dave's Tackle) is consistent with the well-known seasonal pattern of legal-size flounder concentrating on ocean-adjacent structure rather than the back bays this time of year.

No direct comparison to prior-year catch rates or a historical baseline was available in this week's feeds, so beyond noting that the species mix, structure preference, and bait choices all match the expected seasonal template for Delaware Bay NJ in early August, we can't say definitively whether overall volume is running above or below a typical year.
