Big Stripers Firing Island-Wide as Fluke and Sea Bass Season Opens

What's Biting

What's Next

The waxing crescent moon means tidal amplitude will grow through the week ahead, building toward a more productive phase for rip and inlet fishing. Moving tides and early mornings have been the formula for the best striper shots, per River Bay Outfitters (The Fisherman — Long Island West End), and Sea Rogue Charters confirmed the outgoing tide produced the best fluke results in the bay. Plan your sessions around these windows.

Water temps at 56–57°F are close but not yet at the 60°F threshold that typically triggers the fluke bite across Long Island's back bays in earnest. The Fisherman — Long Island East End's Matt Broderick specifically notes that cooler-than-average temperatures are holding the flounder action back, but expects a quick improvement once conditions warm a few more degrees. In the meantime, target channel edges and drop-offs on the outgoing tide with Gulp or squid-tipped bucktails. Quality fish are already present — Sea Rogue Charters pulled a 7-pounder midweek and nine keepers on Saturday in the West End bay — they just aren't yet concentrated in numbers across the board.

Stripers should remain the dominant story through the weekend and into next week. OTW Saltwater's May 12 migration report confirmed 50-pound-class fish stationed off Long Island ahead of the new moon, and the May 15 migration map shows the run's leading edge reaching Maine — meaning the main body of migrating fish is actively moving through Long Island waters right now. The organizing principle is bait: Hi-Hook Bait and Tackle (The Fisherman — Long Island North Shore) points to bunker schools around Eaton's Neck as the magnet, with Mojo trolling, flutter spoons, and bunker chunking all producing on the North Shore. At the inlets and in the surf, Tight Lines Tackle (The Fisherman — Long Island Surf) reported bass to 35 lbs at Shinnecock Inlet on bucktails, with both daytime and after-dark bites running strong.

Black sea bass just opened May 16, and the early returns have been modest. J&J Sports (The Fisherman — Long Island South Shore) reports wrecks and artificial reefs along the South Shore holding keeper-sized fish on clam and squid bait rigs or jigging. Expect the bite to build through late May as captains dial in and bottom temperatures climb.

Watch for bluefish to enter the mix as water temperatures push toward 60°F. J&J Sports (South Shore) reported 5-lb blues already showing at Patchogue's Mascot Dock, and WeGo Bait and Tackle (The Fisherman — Long Island Surf) flagged scattered reports of bluefish around Orient Point. Once temps consistently clear 60°F, blues tend to push across all fronts — inlets, open beaches, and the back bays alike.

Context

Mid-May is historically the heart of the spring striped bass migration through Long Island and Montauk, and 2026 appears to be delivering on schedule — if not slightly ahead of pace. On The Water — New York / Long Island's May 14 report opened by noting "very big bass" in the South Shore surf "as the new moon approaches," and OTW Saltwater's May 12 migration report confirmed 50-pounders staging off Long Island ahead of that new moon — a pattern consistent with the species' classic pre-spawn and post-spawn staging behavior at this latitude.

Water temperatures at 56–57°F are typical for this window in western Long Island Sound and along the South Shore, though several East End sources — notably The Fisherman — Long Island East End — characterized conditions as "cooler-than-average." In most years, Long Island back-bay temperatures cross 60°F in late May, and the fluke bite transitions from patchy keepers to reliable multi-species action around that threshold. The 2026 readings suggest summer flounder is tracking roughly on the average calendar, perhaps a few days behind in the eastern reaches where cooler temperatures are lingering.

NY DEC Saltwater Fishing and Boating confirms all major recreational seasons are now open — striped bass, summer flounder, scup, and black sea bass — which is the standard mid-May cadence. The scup and sea bass openings historically coincide with fish moving inshore from deeper winter habitat as bottom temperatures rise, and The Fisherman — Long Island East End's Shinnecock Star report of "best porgy fishing of the season so far" suggests that inshore migration is well underway and ahead of the sea bass curve.

One notable 2026 context note: Saltwater Edge Blog (RI) flagged that "the wind machine finally turned off" heading into the May new moon period, allowing more consistent fishable days than the early spring delivered. Multiple Long Island sources echo the same theme — a stretch of improved weather is enabling regular water time after what was apparently a wind-interrupted start to the season. If that weather window holds, the late-May convergence of warming water, concentrated bait, and open seasons across all target species could produce some of the best fishing of the year.
