Striper Push Builds Across Long Island Sound as Water Hits 52°F

What's Biting

What's Next

The two NOAA buoys are showing a slight temperature gradient — 49°F at buoy 44025 on the outer shelf and 52°F at the nearer-shore buoy 44065 — with winds running 3–6 m/s (roughly 7–13 mph) and wave heights of 2–2.3 feet. Those are workable conditions for most inshore platforms, and the mild chop may actually help break up surface glare during dawn and dusk windows.

The biggest wild card over the next two to three days is the Full Moon (today, May 3). Full-Moon tides generate the strongest tidal differentials of the month, pushing fast rips off rocky points, reef ledges, and channel edges throughout Long Island Sound. Work the down-current side of structure where baitfish concentrate — those current seams are where stripers stack. The outgoing tide in the one to two hours after a full-moon high is historically a productive window on the Sound.

Per The Fisherman (Northeast)'s Long Island forecast (April 30), bunker schools are already locking fish in place. Anglers who locate pods of bunker are finding both numbers and size — fish into the 30-inch class and beyond. Fresh bunker chunks on the bottom or under a float are a go-to when bass are keyed on bait; when fish are moving, cycle through soft plastics and bucktails at a retrieve speed matched to the current.

On The Water's Striper Migration Map (May 1) confirms the larger post-spawn females are beginning to leave the Chesapeake and the migration is in its active snowball phase. Those fish are still weeks from Long Island Sound in force, but The Fisherman (Northeast)'s New England report (April 30) puts an already-aggressive wave of 25–40-inch fish pushing north through Narragansett Bay — the leading edge of that wave will filter through the Race and into the eastern Sound as the month progresses.

Weekend plan: target dawn and dusk around the full-moon tide peaks. Work current seams at inlet mouths, off points, and along channel edges. If you're plugging, keep it moving on the break between fast and slow water. If you're chunking, set up up-current of a known holding spot and let the tide do the work.

Fluke season is on the near horizon — neighboring states are opening in the first week of May. Check current Connecticut regulations before targeting flatfish, as opening dates vary by year.

Context

Water temps in the low 50s for early May are right on schedule for Long Island Sound. The Sound typically climbs through this temperature band as sun angle increases and day length extends through mid-spring, so the 52°F reading at buoy 44065 sits within the expected historical range for this stretch of the calendar.

The striper migration front appears to be tracking on time — or slightly early. The Fisherman (Northeast) reported as far back as April 23 that western Long Island Sound already had fish to 30 pounds, which is a benchmark that aligns with an on-schedule or modestly early spring arrival. The same report described the classic mid-spring expansion pattern — schoolies rapidly growing into slot and over-slot fish over the course of just days — which is exactly what anglers in this region watch for as a season-opening signal.

Tautog (blackfish) typically peak in shallow rocky structure through April and into early May in southern New England before warm water pushes them deeper. The Fisherman (Northeast) confirmed the spring tautog bite hit its stride right on cue before the Connecticut season closed April 30 — a normal seasonal arc for the Sound.

On The Water's Striper Migration Map (May 1) frames the broader picture well: once the large post-spawn females leave the Chesapeake, the migration snowballs rapidly. The fish currently showing in Long Island Sound are likely pre-spawn and early-season migrants; the bigger waves typically arrive through the latter half of May and into June as water temperatures in the Sound continue to climb toward the upper 50s and low 60s.

If the pattern holds, the next two to three weeks should represent the best mixed-size striper fishing of the spring season on the Sound — numbers of school and slot fish with a real shot at larger bass mixed in, especially around tide-driven rips and bait concentrations.
