Summer Transition Brings Fluke and Blues to Delaware Bay

What's biting

What's next

With a full moon coinciding with this weekend's fishing, expect exaggerated tidal swings through Delaware Bay over the next several days. Strong outgoing flows will push bait out of the upper bay and concentrate predators along channel edges, sandbars, and submerged structure. The best windows will be the last two hours of the outgoing tide and the first hour of the incoming. Plan around these peak-current periods: slack water consistently underperforms in a tidal estuary like Delaware Bay.

Fluke should be the bread-and-butter target through early July. OTW Northern New Jersey noted fluking bounced back after a brief upwelling as of June 25, and Capt Ron's Atlantic Highlands reports confirm a pattern of decent keeper action mixed with plenty of shorts. Simple rigs with plain bait have been outperforming complex presentations on recent NJ trips, per Capt Ron's. In Delaware Bay, drift fishing channel edges and shoal margins on a moving tide with a bucktail tipped with squid or spearing is the standard late-June approach. Keeper ratios should improve as the month closes out and fish settle into summer holding spots.

Bluefish are active throughout NJ bay and inlet waters, per Fishermans HQ LBI. Blues typically push into Delaware Bay in earnest by late June and can provide fast, hard action on light tackle. Metal spoons, poppers, and cut bait all produce. If bait schools are present near the surface, topwater action around dawn and dusk could be electric under a full moon, particularly on a hard outgoing flow.

Striped bass fishing is winding down from its spring peak but has not shut off. On The Water's June 26 migration map notes bigger bass are keyed on sand eels, squid, and bunker as they shift to summer holding areas. Quality fish may still be found around channel mouths and rip edges at night, with clams and bunker chunks the traditional summer holdover approach after dark.

Sea bass are reportedly running hot in NJ waters, with Blue Chip Sportfishing (NJ) logging near-limit trips on virtually every outing. While sea bass are a nearshore-structure species rather than an upper-bay target, grounds adjacent to the Delaware Bay mouth are within reach for boaters looking to extend the day.

Context

Late June is a classic transitional period for Delaware Bay on the NJ side. The explosive spring striper run that peaks in May has largely concluded, and the fishery pivots toward summer species: fluke, bluefish, and weakfish historically fill the calendar from now through September.

On The Water's June 26 striper migration map characterizes the current moment accurately. The spring run is giving way to summer patterns, with bass moving toward deeper, cooler offshore water or staging near bait concentrations. This is entirely typical for the third and fourth week of June in New Jersey. Anglers who adapt rather than chase the tail end of the striper run will find more productive fishing over the coming weeks.

Fluke fishing in late June is generally the opening chapter of the prime summer flounder season in Delaware Bay. Water temperatures in the low-to-mid 60s, consistent with what Capt Ron's Atlantic Highlands is reporting, are favorable for active flounder. As the season progresses toward mid-July and temperatures push into the upper 60s, fish tend to shift to deeper water and keeper ratios can tighten from shallower drifts.

The current season appears broadly on schedule. Fishermans HQ LBI describes the summer transition as underway this week, with the fishery following expected seasonal patterns. No dramatic anomalies have been flagged in the regional intel: no unusual cold upwellings stalling the warm-up, no early heat spike pushing fish prematurely deep.

The full moon window at the end of June has historically been a reliable trigger for bluefish activity in Delaware Bay shallows, particularly around dawn and dusk when bait schools concentrate near the surface. The combination of the full moon and peak tidal movement this weekend could produce some of the better early-summer action of the season if conditions cooperate.
