Fluke bite stays red hot off Atlantic Highlands as bluefin work the 30-mile line
Capt Ron's out of Atlantic Highlands has logged four straight days of what the boat is calling banner fluke action on Raritan Bay, with multiple anglers boxing their three-fish limit and several doubling up on quality fish in the 3-to-5-pound class; the pool fish over the stretch ran as heavy as 5 lb 12 oz. That puts summer flounder squarely as the region's headline species right now, with open-boat trips leaving daily out of the bay. Offshore, OTW's Northern New Jersey report has bluefin tuna holding within about 30 miles, with bonito mixed into bluefish schools further out, while keeper fluke are also showing on the wreck and reef sites outside the bay proper. Striped bass are quiet for now, typical for the mid-August lull before the fall push. NJDEP is asking anglers to log catches on its summer flounder and black sea bass tally form as it explores future regulation changes, so log your trip if you're keeping fish.

What's next
With a new moon just turned and stronger tidal exchange through Raritan Bay and the Sandy Hook reach, expect current to move bait and fluke around more aggressively over the next few days, which typically sharpens drift-fishing bites on the bay's channel edges and sod banks. If the pattern Capt Ron's has been riding holds, look for the fluke bite to stay strong through the week, though boats note the action has been weather-dependent, with the best days lining up behind calmer, high-pressure stretches. Keep an eye on midweek conditions before booking an open-boat slot.
Offshore, the bluefin tuna holding within 30 miles per OTW's Northern New Jersey report should keep producing on trolling spreads as long as bait stays balled up out there; bonito mixed into bluefish schools is a good early sign that more warm-water pelagics could push into range through late August. Anglers running out of Sandy Hook toward the canyons or the 30-mile line should watch for that bonito/bluefin combo to build before the water starts cooling in September.
Striped bass should stay slow through the rest of August, consistent with the typical late-summer lull in this region before fish stage for the fall run. Bluefish, tautog, and summer flounder were all noted as regular catches around Shark River-area structure per NJ Fish & Wildlife, and similar structure-oriented species should remain catchable around Raritan Bay's reefs and wrecks in the meantime.
Plan around the new moon's bigger tidal swings for the next several days, tightest fishing typically on the stronger moving water around the tide changes. If you're weighing a weekend trip, the fluke bite described by Capt Ron's gives the highest-confidence window right now, with offshore bluefin/bonito trips a solid secondary option for boats willing to run 25-30 miles.
Context
Mid-August in Raritan Bay and around Sandy Hook typically means summer flounder and bluefish carry the inshore action while striped bass sit in a seasonal lull, with anglers waiting on cooler water and bait migrations to trigger the fall run. What we're seeing in the intel above tracks that normal seasonal script closely, the fluke bite Capt Ron's is reporting reads as a strong, on-schedule summer pattern rather than anything early or late, and the bluefin/bonito activity holding offshore is typical for this point in the summer pelagic season.
One thing worth flagging: NJDEP's active push for anglers to use the Summer Flounder & Black Sea Bass Tally Form suggests the state is leaning on angler-reported data more heavily this season to shape future measures, worth knowing if you're fishing for keepers and want your trip to count toward that picture.
Beyond that, none of the feeds available for this report speak directly to how this August compares to prior years in the bay, so we can't make a confident year-over-year call. What's here supports a normal, on-schedule late-summer pattern for the region rather than any notable deviation.
