What You'll Find in West Neck Bay

West Neck Bay is a working harbor on Shelter Island's north shore where striped bass and flounder move through predictable channels between deeper water and the shallows. The bay holds fish year-round, but the real action runs from late spring through fall when stripers push into the shallows to feed and flounder settle into the deeper holes. The water here is cleaner than many bays on the North Fork side, and the bottom—a mix of sand, mud, and shell—holds baitfish that keep the larger fish coming back.

Access is straightforward if you have a boat. The bay opens to Gardiner's Bay on its eastern end, and several launch ramps and mooring fields serve the local fishing community. If you're new to the area, the key is understanding that West Neck is tidal and narrow in places, so timing your run with the current makes a real difference in how fish behave and where they hold.

Key Takeaways

  • Striped bass in West Neck Bay respond best to live bunker and eels in the deeper channels during slack tide, when they're not fighting current.
  • Flounder fishing peaks in June and July in the 15- to 25-foot holes along the bay's western side, where the bottom transitions from sand to mud.
  • The bay's narrow mouth means tidal flow is strong; fishing the first and last hour of the tide change produces more strikes than mid-tide.
  • Shelter Island's town launch at Dering Harbor is the closest public access, and mooring field operators can point you to the best holding water for your target species.

Striped Bass Patterns Through the Year

Spring stripers (April through May) move into West Neck as water temperatures climb past 50 degrees. They're not deep yet—look for them in 8 to 12 feet of water along the channel edges where baitfish congregate. Live bunker works, but so does a 4-inch white shad on a light jig head if you're casting from a drifting boat. The bite is often best in the hour after sunrise and the two hours before sunset.

Summer (June through August) pushes the larger stripers deeper into the 18- to 25-foot holes, especially during the heat of midday. Early morning and evening, smaller fish and schoolies will chase topwater plugs in the shallower arms of the bay. If you're fishing live eels at night, anchor in 12 to 15 feet and let the tide work for you—the eels will find the fish without you having to cast constantly.

Fall (September through October) is when West Neck produces its best fishing. Water cools, baitfish bunch up, and stripers feed aggressively from dawn until mid-morning. The deeper channels hold the most consistent fish, but don't ignore the shallow flats on the western side when the tide is high—stripers will hunt there for an hour or two before dropping back to deeper water.

Flounder and Summer Flatfish

Flounder move into West Neck in late May and stay through September, with peak numbers in June and July. The best holding water is the 20- to 28-foot zone along the western side of the bay, where the bottom shifts from sand to soft mud. Anchor uptide of these holes and work small squid strips or live spearing on a simple two-hook rig—flounder aren't aggressive, so light tackle and patience matter more than flashy presentations.

The bite is steadiest on the incoming tide, especially the first two hours after slack water. Flounder will move up from the deeper holes to hunt in 12 to 15 feet as the tide pushes water in from Gardiner's Bay. If you're fishing during the day, expect the bite to slow between 10 a.m. and 3 p.m.; dawn and dusk are more reliable. Many anglers also catch scup and sea bass in the same holes, so bring appropriate tackle for all three.

Launch Ramps and Mooring Fields

Dering Harbor, on Shelter Island's south shore, has the closest public launch ramp to West Neck Bay. The ramp is town-maintained and typically open year-round, though winter weather can make it rough. Parking is limited, so arrive early on weekends. From Dering, it's a short run north through the narrow channel into West Neck proper.

If you keep a boat on moorings, several field operators work the bay and can advise on the best water for your target species. They also know the bottom, the current patterns, and which spots hold fish in different seasons. A conversation with a mooring field operator is often worth more than a guidebook—they see the water change week to week and know what's working that day.

Tidal Flow and Timing

West Neck Bay's narrow mouth means tidal current is strong and predictable. The incoming tide pushes water from Gardiner's Bay into the bay, concentrating baitfish and stripers in the channels. The outgoing tide reverses the flow, and fish often move to the deeper holes to wait out the current. Slack water—the 20 to 30 minutes when the tide pauses between incoming and outgoing—is when fish feed most actively because they're not fighting current.

Plan your fishing around slack water if you can. If you're drifting, time your drift to start just before slack and ride it through the first hour of the new tide. If you're anchored, position yourself uptide of a known holding spot and let the current bring baitfish and fish to you. Ignoring the tide is the fastest way to waste a day in West Neck.

Seasonal Access and Weather Considerations

West Neck Bay is fishable year-round, but winter (November through March) brings rough water and short days. Spring and fall offer the most reliable weather and the best fishing. Summer can be crowded with recreational boaters on weekends, so weekday mornings are quieter and often more productive.

The bay is exposed to the north, so northeast winds can make it choppy quickly. Check the forecast before you launch, especially in spring and fall when weather can change fast. A 15-knot northeast wind can turn a calm morning into a rough afternoon in an hour. Local tackle shops on Shelter Island and the North Fork can give you a real-time read on conditions and what's biting.

Tackle and Bait Recommendations

For striped bass, bring 20- to 30-pound braided line on a medium-heavy spinning rod. Live bunker and eels are the standard baits, but 4- to 5-inch shads on light jig heads work well for casting. Topwater plugs in white or chartreuse produce in early morning and at dusk. A 2/0 to 4/0 circle hook is standard for live bait; it hooks the fish in the corner of the mouth and reduces gut-hooking.

For flounder, drop down to 15- to 20-pound line and use a simple two-hook rig with small squid strips or live spearing. A 1/4-ounce sinker is usually enough to hold bottom in the 20-foot holes. Flounder bite soft, so set the hook with a steady upward motion rather than a sharp jerk—you're driving the hook home, not yanking the rod.

Frequently Asked Questions

Can I fish West Neck Bay from shore?

Shore access is limited. Most of the bay's shoreline is private property or town land without public parking. Your best option is to fish from a boat launched at Dering Harbor or to ask a local tackle shop about any public access points that may have opened recently.

What's the best time of day to fish West Neck?

Early morning (one hour before sunrise to two hours after) and the last two hours before sunset are most reliable. Midday fishing is slower, especially in summer. If you're fishing at night, anchor in a known holding spot and fish live eels on the incoming tide.

Do I need a New York State fishing license to fish West Neck Bay?

Yes. New York requires a saltwater fishing license for anyone 16 and older. You can purchase one online through the New York Department of Environmental Conservation website or at most local tackle shops.

What's the minimum size for striped bass in West Neck?

New York's minimum size for striped bass is 18 inches. Check the current regulations with the DEC before you fish, as rules can change. Local tackle shops always have the most recent information posted.

How deep is West Neck Bay?

The bay ranges from 8 feet in the shallower arms to 28 feet in the deepest holes along the western side. Most productive fishing happens in 12 to 25 feet of water, depending on the season and target species.
