Flounder Bite Loads Up Delaware Bay's Back Bays

What's biting

What's next

With the flounder bite building steadily through the back bays, the next few days should keep favoring the incoming tide as the primary window. Pier 47 Marina's report of a dozen-to-three-dozen fish per trip on the flood suggests bait and current are lining up well right now, and that pattern typically holds as long as water clarity stays decent after any rain. Anglers working Cape May to Stone Harbor should plan trips around the top of the incoming water, with live minnows and strip baits as the go-to, and 3-inch Gulp Mullets as the artificial backup when bait supply runs thin.

The keeper-size trend is worth watching closely. Big Dave's Tackle notes that fish get bigger the farther you range from the back bays toward the reef sites and oceanfront beaches, and Hands Too Bait and Tackle's report of Old Grounds fish topping 7 pounds suggests the deeper structure is holding the better class of flounder right now. If that pattern continues into the weekend, boaters willing to make the run to Wildwood and Cape May Reefs, or out to the Old Grounds, should keep finding a stronger ratio of keepers to shorts than the back-bay crowd is seeing.

Croaker, spot, and the occasional black drum should keep showing as reliable bycatch on bottom rigs fished alongside the flounder spread. That mixed bag has been consistent per Higbee's Bait and Tackle and isn't likely to change much through the next few days barring a big weather shift. Weakfish will probably stay a scattered, short-fish story rather than a targeted bite; nothing in current reports points to a turn-on there yet.

For surf and jetty anglers, Cape May Point continues to be worth a look for flounder and weakfish, with a sheepshead possible around structure, per Hands Too Bait and Tackle. Just outside the bay mouth, bluefin have been working the inshore lumps, so boats that can make the run may find a bonus tuna bite mixed into an otherwise flounder-focused trip.

Plan around the moon: a waxing gibbous heading toward full typically means stronger tide swings over the coming days, which should keep pushing bait and fish onto the structure that's already producing. Check the local forecast before heading out, since no live wind or sky data is available for this report.

Context

Late July is peak summer flounder season in Delaware Bay's back bays and reef structure, and this week's reports track with that seasonal norm rather than running notably early or late. Flounder pressure and catch rates typically build through June and hold strong into August as fish stack up on structure in the warmer months. The 'off the charts' language from Big Dave's Tackle and 'loaded' call from Pier 47 Marina reads as a solidly on-schedule summer bite rather than an unusual spike.

The reported shift toward keepers appearing in the bay itself, not just the deeper reef sites, is worth flagging: earlier in the season keeper-class fish tend to concentrate on structure like the Old Grounds and ocean reefs while back-bay fish run short, so more keepers showing up in the bays themselves suggests the fishery is progressing normally into its mid-to-late-summer phase.

Weakfish showing as scattered bycatch rather than a targeted fishery is consistent with the species' well-known long-term regional decline, though the available reports here don't offer enough specific historical comparison to say whether this week is better or worse than recent seasons for weakfish specifically.

No buoy or gauge data was available for this report, so there's no water-temperature or flow trend to compare against a historical baseline this cycle. That comparison should be treated as unavailable rather than assumed favorable or unfavorable.
