Long Island Sound Loaded With Big Bass for Memorial Day Weekend
Water temperatures have climbed to 55°F across Long Island Sound, per NOAA buoys 44025 and 44065, and the timing couldn't be better — multiple Connecticut tackle shops are reporting the best striper bite in years. Fisherman's World described this week as simply "bass, bass, bass," with fish caught on virtually every method across inshore and deep water alike. The Fisherman's Connecticut roundup, drawing on reports from Aaron Swanson and area shops, confirms the May new moon supercharged bass activity throughout LIS and its tributaries, with fish feeding on squid, bunker, mackerel, herring, and silversides. Captain Morgan's Bait and Tackle reported that artificials, including flies, are easily keeping pace with live bait, and noted tide rather than time of day is the primary variable right now. OTW Saltwater's May 19 striper migration report confirmed Long Island Sound is "loaded with big bass on bunker." Bluefish have just arrived in southern New England and are beginning to filter into the region.

What's Next
The current setup in Long Island Sound is about as good as it gets for late May. With water holding at 55°F and a dense forage base spread throughout the Sound, striped bass remain the dominant story heading into Memorial Day weekend. Bobby J's noted that inshore action is currently outpacing deep-water fishing — a pattern worth noting for shore and nearshore boat anglers. On the reefs, Bobby J's was specific: fish an outgoing tide for best results right now.
Captain Morgan's Bait and Tackle described a "buffet striped bass will have a hard time ignoring" — squid in deep water, herring in the shallows, live eels, menhaden, and seaworms all in play. Critically, the shop noted that artificials, including flies, are keeping easy pace with live bait, and that big fish are tearing up shallow structure on tidal rhythm rather than first light alone. That means productive windows aren't limited to pre-dawn runs; work your structure through the outgoing current and the fish should cooperate.
Current sea conditions are rough, with NOAA buoy 44025 recording 6.6-foot wave heights and buoy 44065 clocking winds around 10 meters per second. Anglers should check updated forecasts before heading out this weekend and consider sheltered inshore spots, river mouths, and tributary staging areas if offshore conditions don't lay down. The bass bite doesn't require blue water right now — fish are well-distributed across inshore flats, structure, and estuaries.
Bluefish are the species to watch over the next several days. The Fisherman (Northeast) reported bluefish arriving at three locations across southern New England just ahead of Memorial Day weekend, with expectations they'll continue spreading east and west. As they push into LIS, boat anglers working surface plugs and metal — especially during active surface-feeding sessions — should start intercepting them. Keep a wire leader or short-bite fluorocarbon ready.
Fluke are beginning to stir regionally. The Fisherman — Rhode Island noted keeper fluke catches on the grounds last week via the Frances Fleet report, and with LIS water now at 55°F, summer flounder will increasingly move onto shallower sandy structure. Bucktails and soft plastics drifted over nearshore bottom should become progressively more productive over the coming week or two as water continues to warm. If conditions calm midweek, the inshore striper bite across the Sound should remain exceptional — the bait base of bunker, mackerel, squid, and silversides is not going anywhere soon.
Context
Late May in Long Island Sound is typically prime time for the spring striper migration, and the 2026 season is delivering. Water temperatures of 55°F are on the cooler end of the normal late-May range for LIS — historical averages typically sit between 57°F and 62°F by Memorial Day — but the dense bait presence is more than compensating.
The Fisherman (Northeast) offered a notable benchmark heading into this weekend: the current spring push of 20- to 30-pound fish is described as "the likes of which we haven't seen in many years." That framing suggests 2026 is not just a good striper spring — it may be shaping up as one of the better ones in recent memory, at least in terms of fish size. OTW Saltwater's migration tracking corroborates the story: fish were already confirmed loaded in Long Island Sound on bunker by mid-May and had reached as far north as Maine — a broad push that arrived on the earlier end of typical.
Bluefish generally don't show in force in southern New England until late May or early June, so their confirmed arrival at multiple locations during the week of May 19 is slightly ahead of schedule — a positive indicator for LIS anglers heading into the holiday weekend and beyond.
Fluke (summer flounder) typically become consistently catchable in LIS once water temperatures stabilize above 55-57°F, meaning the season is just now crossing its threshold. Expect the bite to improve steadily through June. Tautog are not specifically called out in Connecticut sources this cycle, but blackfish on rocky structure are a staple LIS species through late May and are worth targeting alongside bass until the water pushes into the mid-60s.
Overall, 2026 is tracking as an above-average spring for Long Island Sound, anchored by an exceptional striper run and a bait situation that multiple regional sources describe as unusually dense.
