Fall run heats up on Long Island as albies and bluefish flood the inlets

What's biting

What's next

With bait — peanut bunker, spearing, and rainfish — pushing out of the bays and estuaries per multiple South Shore and North Shore shops, expect the bluefish pattern to keep intensifying into the weekend as cooler nights push baitfish tighter against the beaches and inlets. White Water Outfitters and East End Bait and Tackle both note the albie and bonito bite at Shinnecock hasn't been especially tide-dependent this week thanks to sheer bait volume, but as that volume thins, working the peak of the tide change should start to matter more.

The striped bass trend is the one to watch closest. Tight Lines Tackle already has Montauk's ocean beaches producing stripers from dusk into full dark on tins and bucktails, and with the first-quarter moon giving way to darker nights through the week, that after-sunset window should keep expanding. Anglers planning a weekend trip should target the last two hours of daylight through the first hour of full dark, from Montauk Point west through the South Fork.

Fluke season is closing rather than building, but don't write it off — Bob's Bait and Tackle in Amity Harbor notes that, in their experience, the last three to five years have actually produced the best fluke fishing of the season in late September, particularly in the ocean where keeper ratios are holding up better than in the bays, per several South Shore and West End reports.

Offshore, the bluefin and yellowfin bite Tyalure Professional Tackle describes five miles off Shinnecock and Montauk, along the 20- and 30-fathom curves, should hold as long as bait stays stacked along that break — worth a run for boats able to get out before conditions turn, though Bergen Bay Docks notes the tuna bite has already started to slow at their end with mahimahi filling in instead. Bottom fishing (porgies, sea bass) should stay a dependable fallback on any day the surface bite goes quiet, per shop reports spanning the North Shore, South Shore, and East End this week.

Context

Late September is peak fall-run season for Long Island and Montauk, and this week's reports track close to that seasonal script: albies and bonito moving through the inlets, bluefish schooling up on bait, and striped bass beginning to show more consistently as nights cool — a fairly typical late-summer-into-fall progression for the region. The Fisherman's Long Island Video Fishing Forecast for September 17 frames this directly as the fall scene "beginning to take shape," with better striper numbers on both the East End and South Shore and steady fluke holding up alongside it, which lines up with what individual shops are reporting on the ground.

One notable wrinkle: Bob's Bait and Tackle in Amity Harbor points out that the last three to five years have actually delivered their best fluke fishing in the final weeks of September, which runs counter to the usual assumption that the fluke bite fades by now — worth keeping in mind rather than assuming the season is done.

No NOAA buoy or USGS gauge readings were available for this report, so water temperature and wave/tide numbers can't be verified directly this cycle; conditions described here lean entirely on angler and shop reports rather than instrument data.
