Fluke dominates Long Island as bluefin bite stays red-hot

What's biting

What's next

With Spanish mackerel and bonito trickling in out east and building through the inlets per On The Water — New York / Long Island, expect that hardtail action to keep expanding along the South Fork and North Shore over the next several days. WeGo Bait and Tackle and River Bay Outfitters are already seeing Spanish mackerel show on the Sound side and out east, and that pattern typically firms up through late August as bait schools continue pushing west.

The fluke bite should hold through the week as long as tide and wind cooperate. Several South Shore and West End shops describe strong numbers of shorts mixed with a manageable pick of keepers — Fishfinder II is seeing pool fish in the 6-to-8-pound class on the outside reef, and Bay Park Fishing Station and Captain Dave III report solid, if unspectacular, keeper ratios. The one soft spot flagged this week is current-dependent: Shamrock Charterboat noted the Sunset Fluke run has struggled when wind runs against tide and kills the drift, so plan trips around stronger moving water rather than slack stretches.

Offshore, the bluefin tuna bite is the standout and should stay active into the weekend. Trophy Hunter Montauk Charters and Double D Charters both describe consistent action, and Tight Lines Tackle-East End notes the jig bite has been outperforming trolling, with fish in the 35-to-60-inch class showing anywhere from about 5 to 40-plus miles offshore. On The Water — New York / Long Island adds that yellowfin are beginning to move in closer to the midshore grounds, typically an early signal of a bigger push as water temperatures ease off their summer peak.

Striped bass remain the wildcard. The Fisherman — Long Island Surf and Fishing East Coast Bait and Tackle both describe the daytime bite as limited, which tracks with typical August warmth, but night sessions on live eels and darters are still producing fish. Around the first-quarter moon, look to the last hour of daylight and after-dark windows — Miller Place Bait and Tackle and WeGo Bait and Tackle both report bass and bluefish responding to topwater plugs and darters around points and docks.

Looking further out, Saltwater Edge Blog (RI) frames this stretch of August as the doorstep to the fall run, with cooler mornings starting to show even as midday heat lingers — a pattern worth watching on Long Island as bait begins staging for the seasonal push south.

Context

Late-August patterns on Long Island typically hinge on the fluke-to-striper handoff, and this stretch is running true to that script: fluke remain the most consistent, highest-volume bite across nearly every shop report gathered here, from Sheepshead Bay in the West End to Shinnecock Bay out east, while striped bass have eased into their typical summer lull. Multiple North Shore and Surf sources describe bass as thinned out or limited right now, which lines up with the seasonal pattern of daytime bass activity slowing through the warmest weeks of August before picking back up as water temperatures ease into September.

The bluefin tuna bite this week reads a bit stronger than a typical mid-to-late August window — Trophy Hunter Montauk Charters and Double D Charters both describe sustained, close-to-shore action, and On The Water — New York / Long Island notes yellowfin already easing into the midshore grounds, which is often more of a September signal. That's worth watching as a potentially early offshore push.

Regionally, Saltwater Edge Blog (RI), covering the broader Northeast surf and coastal scene, frames the season as coming off "a pretty lackluster July" before turning a corner into August, with the fall run "on our doorstep" — a framing that lines up with the NY DEC Saltwater Fishing and Boating office's ongoing seasonal notices on the state's open summer flounder, scup and black sea bass seasons (check current state regs before harvesting).
