Fluke fires up on South Shore reefs as gator blues crash Montauk

What's biting

What's next

If the pattern holds, look for the fluke bite to keep building over the next few days. On The Water — New York / Long Island noted keeper-grade flounder pushing from the South Shore reefs and back bays into Long Island Sound as of July 16, and with the summer flounder season freshly underway per NY DEC, pressure and numbers typically climb through late July as fish settle onto structure. Bucktails tipped with Gulp trailers worked slow along reef edges should keep producing.

Gator bluefish should stay thick off Montauk in the near term. Blues tend to move in waves as they chase bait schools, so anglers working that stretch can expect good windows even if the fish shift location day to day. NY DEC's newsletter flags a recreational bluefish regulation change this season (no size limit, five fish per angler, snappers unlimited) — worth a look before keeping a cooler full of choppers.

The Montauk striped bass bite is the one trend worth watching closely. On The Water's July 9 report already flagged the big-bass bite beginning to slow, and that typically continues through peak summer as fish ease toward cooler, deeper water or push further along the migration route. Surfcasters chasing stripers in this stretch may want to lean on eels or rigged Slug-Gos worked after dark, and try deeper rips in Long Island Sound with a 3-way bucktail rig rather than daytime shallow structure.

Offshore, midshore bluefin remain available but are described as on the move rather than holding, and the broader Northeast offshore picture shows yellowfin building in the canyons with bluefin spreading from New Jersey up toward the Gulf of Maine. Boats able to run midshore or beyond in the coming days should find a mixed tuna bite, though exact position will keep shifting with the fish.

Context

Mid-July on Long Island and off Montauk typically means a fishery in transition, and this stretch is following that script closely. The big striped bass bite that builds through spring and early summer around Montauk normally starts easing by mid-July as fish disperse and seek cooler water, and On The Water's own reporting shows exactly that shift between its July 9 and July 16 updates. That's on-schedule, not early or late.

Summer flounder (fluke) improving from the reefs and back bays into Long Island Sound also tracks typical seasonal timing, especially with the state's summer flounder season having just opened per NY DEC. Gator bluefish showing up in numbers off Montauk in mid-summer is a familiar pattern as well, consistent with the regulation notes DEC issued around bluefish this season.

The angler-intel feeds don't include direct season-over-season comparisons (no mention of this year running notably hot, cold, early, or late relative to prior seasons), so beyond the general seasonal cadence described above, there isn't a specific comparative data point to lean on here. Anglers should treat this as a normal mid-summer transition period rather than an anomalous one, with the usual caveat to check current state regulations before harvesting striped bass, fluke, or bluefish.
