Full moon current fuels fluke, sea bass, and shark action across NJ

What's biting

What's next

With a full moon on tap, expect stronger tidal swings and faster-moving water over the next few days, which usually concentrates bait and predators around structure, inlets, and current breaks. Grumpys Tackle (NJ) reports fluke fishing 'showing steady improvement' in the surf on bucktails and scented soft plastics, and that trend should continue building through the first week of August as water temperatures hold in the typical summer range for flatfish.

Croaker and spot look like the most dependable back-bay bite right now per Grumpys Tackle (NJ), with FishBites and natural bait working for both, and crabbing described as 'good too.' Expect that pattern to hold through the late-July doldrums into early August. Weakfish, by contrast, haven't materialized as hoped: Fishermans HQ LBI (NJ) targeted weakfish and kingfish with live shedder crabs but found 'the only fish that cooperated were croakers,' a sign weakfish remain a lower-percentage target for now, with croaker and fluke the better bet on bait.

Sea bass should stay a strong play on structure. Capt Ron's Atlantic Highlands NJ crew has been 'limiting out on almost every trip,' with jumbo sea bass finally showing consistently around the boat, best on jigs and Gulp. If that holds, weekend trips to reef and wreck bottom should keep producing.

Striper and shark activity described by Blue Chip Sportfishing (NJ), including multiple released makos and stripers on 'every trip,' points to elevated predator activity right now. Expect that to continue into early August as bait stays thick, with Fishermans HQ LBI (NJ) noting a 'massive squid invasion' that has bluefin tuna within striking range 20 to 30 miles out.

Plan trips around the moving tide stages surrounding the full moon for the strongest bites, and check NJ Fish & Wildlife News and current state regulations before harvesting anything, since size and possession limits can shift seasonally.

Context

Late July into the Delaware Bay region typically settles into a summer pattern: weakfish activity tapers from its spring peak, croaker and crabbing carry the back bays, and striped bass become a more specialized, current- and structure-dependent target as water warms. Nothing in this cycle's intel contradicts that rhythm. Fishermans HQ LBI (NJ)'s note that shedder crabs drew mostly croaker instead of the targeted weakfish and kingfish fits the expected mid-to-late-summer weakfish slowdown.

What stands out this cycle is the sea bass and mako shark activity described by Capt Ron's Atlantic Highlands NJ and Blue Chip Sportfishing (NJ), both stronger than a typical late-July lull. Those reports come from ocean-side and inshore NJ locations rather than the bay itself, so they should be read as regional New Jersey context rather than a direct Delaware Bay read. NJ Fish & Wildlife News did not publish region- or species-specific fishing intel this cycle (its recent posts covered WMA habitat highlights and archery infrastructure), so there is no state-agency confirmation specific to Delaware Bay conditions this week.

No buoy or gauge telemetry came through for this report, so there is no direct water-temperature or current-speed comparison to prior weeks available. Anglers fishing the bay directly should weigh these NJ-wide reports as general seasonal context and confirm local conditions before heading out.
