What You'll Find in Quincy Bay

Quincy Bay holds striped bass, flounder, and bluefish in a working harbor that's less crowded than Boston's inner islands but still productive year-round. The bay runs roughly three miles from the Fore River Bridge south to Spectacle Island, with depths ranging from 15 to 40 feet depending on where you fish. Access is straightforward—you can launch from Squantum Point or fish from the public piers at Marina Bay, and the water stays fishable even when the Charles River and inner harbor get too silted or warm.

Spring and fall are the strongest seasons here. Stripers move through in April and May heading to summer grounds, then return in September and October on the way back out. Summer holds resident fish and flounder, though the heat can slow the bite during midday. Winter is quieter but not dead—you'll find stripers and the occasional large flounder if you fish the deeper channels.

Key Takeaways

  • Striped bass move through Quincy Bay in spring (April–May) and fall (September–October), with the best fishing in early morning and late afternoon during warm months.
  • Flounder hold year-round in the deeper channels and around structure, with summer and early fall producing the most consistent action.
  • Launch from Squantum Point or fish the public piers at Marina Bay; both offer easy access without a private boat.
  • Tide matters more than time of day in Quincy Bay—fish the moving water on the incoming and outgoing tide, especially around the Fore River Bridge.
  • Live mackerel, herring, and soft plastics work well; stick with natural colors in spring and fall, brighter patterns in summer.

Spring Stripers and the Fore River Bridge

April through May is when Quincy Bay fills with migrating stripers heading north to the Merrimack and other summer rivers. The Fore River Bridge is the focal point—stripers stack up there on the incoming tide, using the current break to rest and feed. Fish the hour before high tide through the first hour of the outgoing tide; the window is tight but productive.

Live mackerel or herring work best, cast or drifted near the pilings. If you're shore fishing from Marina Bay, focus on the deeper water on the eastern side of the bay where the channel runs closest to the piers. Stripers in spring are aggressive and hungry after the winter, so you don't need to overthink presentation—a simple live bait rig or a 3/4-ounce white or chartreuse bucktail will draw strikes.

Water temperature is the key variable. Once the bay hits 55 degrees, the bite turns on; by late May, as water climbs toward 65, the fish begin to thin out and move deeper or further north. Check the water temperature before you go—if it's still in the low 50s, the bite will be spotty.

Summer Flounder and Resident Bass

June through August, the stripers that didn't leave settle into the deeper holes and channels, and flounder move in to hunt the sandy bottom. The best summer flounder fishing happens in the early morning or late evening when the water is cooler and the fish are more active. Midday can be slow, especially in July and August when the bay warms.

Fish the channels south of the Fore River Bridge and around the deeper water near Spectacle Island. Soft plastics—4 to 5-inch shads in natural colors like pearl, chartreuse, or pumpkinseed—work well drifted or cast and retrieved slowly along the bottom. Flounder will also take live mackerel or herring, though they're less aggressive hunters than stripers and may mouth the bait before committing.

Summer resident stripers are often smaller than the spring migrants, but they're plentiful and willing. The same soft plastics and live bait work for both species, so you're not choosing between them—you're fishing for whatever bites. Bring extra tackle because the bottom in Quincy Bay has rocks and debris that will snag you.

Fall Migration and Peak Conditions

September and October bring the best overall fishing of the year. Stripers return from their summer grounds, water temperatures drop back into the 60s, and the fish feed aggressively in preparation for winter. The Fore River Bridge is productive again, and the entire bay wakes up. You'll see more boats in the water during fall than any other season, but there's enough fish to go around.

The outgoing tide is often better in fall than the incoming—stripers seem to prefer moving with the current as it flows toward the ocean. Fish the hour before low tide through the first two hours of the outgoing tide. Live mackerel is the standard bait, but if you're casting, switch to darker colors—black, dark olive, or dark purple bucktails and soft plastics. The light is lower in fall, and darker lures are easier for the fish to see.

Fall also brings bluefish into the bay. They're aggressive and will hit anything that moves, but they'll also cut through your line with their teeth. If you're targeting stripers and want to avoid bluefish, use live bait instead of artificials—blues are less interested in live offerings than stripers are. If you want to fish for blues, use a wire bite leader and expect fast, hard strikes.

Winter Fishing and Deeper Channels

November through March is quiet, but it's not empty. Stripers and flounder move into the deepest channels and hold tight. The Fore River Bridge area and the channel south toward Spectacle Island are your best bets. Fish the slack water around high and low tide when the current isn't pushing the fish around—they're less willing to chase in cold water, so you need to put the bait or lure right in front of them.

Winter flounder are larger and more selective than their summer cousins. Live mackerel or herring fished on the bottom with a simple two-hook rig works well. Stripers are fewer but bigger—the small fish have moved out, and what remains are the larger residents and occasional migrants. Jigging with heavy bucktails or soft plastics in the deep channels can produce, but you need patience and a willingness to fish slowly.

Launch and Shore Access

Squantum Point has a public boat ramp with parking and is the easiest launch in the area. The ramp is maintained year-round, though it can get crowded on weekends during spring and fall. There's a small fee for launching. If you don't have a boat, the public piers at Marina Bay offer shore access without a launch fee. The piers are open to the public and give you access to the deeper water on the eastern side of the bay.

Parking at Marina Bay is limited but available. The piers are best fished on the incoming tide when the current brings bait and fish closer to shore. Early morning is less crowded than afternoon, and you'll have more room to cast without tangling with other anglers.

Tackle and Bait Recommendations

Live mackerel and herring are the standard baits and work year-round. You can catch your own with a small net or sabiki rig, or buy them fresh from local tackle shops. If you're casting, carry bucktails in sizes from 1/2 ounce to 1.5 ounces depending on the current and depth. White, chartreuse, and dark colors all work—white and chartreuse in spring and summer, darker colors in fall and winter.

Soft plastics in the 4 to 5-inch range are effective for both stripers and flounder. Shad patterns in pearl, chartreuse, and pumpkinseed are reliable. Bring a wire bite leader if you're fishing for bluefish or expect them in the mix. A simple two-hook bottom rig with small sinkers works for flounder and winter fishing. Most of the fish in Quincy Bay are in the 18 to 28-inch range, so medium-action spinning rods and 15 to 20-pound braid are adequate.

Frequently Asked Questions

What's the best tide to fish Quincy Bay?

The moving water on the incoming and outgoing tide is better than slack water. The Fore River Bridge is most productive on the incoming tide in spring and the outgoing tide in fall. Check a tide table before you go—the timing shifts by about 50 minutes each day.

Can I fish Quincy Bay from shore without a boat?

Yes. Marina Bay has public piers that give you access to deeper water. The piers are best fished on the incoming tide. You can also fish from the rocks and shoreline around Squantum Point, though the piers are more productive.

What size fish should I expect?

Stripers typically run 18 to 28 inches, with occasional fish in the 30-inch range. Flounder are usually 15 to 22 inches. Spring migrants are often larger than summer residents. Winter fish tend to be bigger because the smaller fish have left.

Do I need a saltwater fishing license to fish Quincy Bay?

Massachusetts requires a saltwater fishing license for anyone 16 and older. You can get one online through the Massachusetts Division of Marine Fisheries or at most tackle shops. The license is inexpensive and valid for one year from the date of purchase.

What's the difference between fishing the bridge and fishing the open bay?

The bridge concentrates fish because of the current break and structure. The open bay is less predictable but can hold scattered fish, especially in summer and winter. The bridge is best for spring and fall migrants; the open bay is better for summer flounder and resident stripers.
