The Fall Striper Migration: How to Follow and Catch Striped Bass in October
The fall striper run is Connecticut's most anticipated fishing event of the year. Starting in late September and reaching peak intensity in October through early November, large striped bass move south through Long Island Sound from their summer grounds in New England waters — and the CT coast lies directly in their path. The fish feeding in October are typically the largest of the season: 30-inch-plus bass gorging on the abundant bunker and mullet schools that share the migration path south. For shore anglers, surf casters, and small boat fishermen, this is the window that CT striper fishing exists for.
Understanding the Migration Timeline
The fall striper migration follows water temperature more reliably than the calendar. Large stripers begin moving south from summer grounds (Cape Cod, Rhode Island waters) when surface temperatures drop below 65°F — typically late September to early October in CT waters. The peak migration through Long Island Sound occurs when temperatures are between 58–65°F, generally mid to late October in most years. By mid-November, water temperatures drop below 55°F and the main body of fish has pushed past CT toward New Jersey and the Chesapeake. The window is roughly 6 weeks — but within that window, certain weeks are dramatically better than others based on current temperature and baitfish presence.
Where to Follow the Migration Week-by-Week
The migration moves generally west and south through the Sound, so eastern CT sees fish before western CT. **Late September – early October:** Stripers first appear at the eastern end of the Sound — the Race, Fishers Island Sound, and the areas around Groton, Mystic, and Stonington. Smaller fish (schoolies) arrive first; larger fish follow. **Mid-October:** The main body of fish moves through the central Sound — from the Connecticut River mouth west through Clinton, Westbrook, and Madison. Bunker schools visible offshore are the leading indicator. **Late October – early November:** The heaviest run of large fish typically passes through western CT (Guilford, Branford, New Haven, Greenwich) as the front edge of the migration pushes through. The Greenwich and Norwalk shoreline can produce 30"+ fish during this window. **Monitor water temperature:** The NERACOOS real-time coastal ocean observation data shows current Sound surface temperatures — when CT water is in the 60–65°F range, the best fishing window is active.
The Bunker Schools: Following the Food
Large fall stripers are following bunker (menhaden). The fish migration and the bunker migration are inseparable — where the bunker schools are, the large stripers are beneath and around them. **How to find bunker:** Birds (gannets, terns, cormorants) diving on a specific area indicate surface baitfish activity. Oil slicks on the water surface indicate crushed bunker. Sonar returns show dense schools in the upper water column. A 'nervous water' disturbance — thousands of small fish creating surface dimples — visible from the boat or shore. **Intercept, don't chase:** Position ahead of a moving school rather than running into it. Cut off the school's direction of travel, anchor or drift in the path, and let the fish come to you.
Fall Run Tactics and Lures
**Live bunker:** The most reliable big-fish technique during the fall run. A 4"–6" live bunker, free-lined or under a large foam float, presented at the edge of a school produces the largest stripers of the year. **Chunk bunker:** Fished on the bottom below bunker schools where bass that aren't surface-feeding are feeding at depth. A 3 oz sinker on a fish-finder rig with a circle hook and a fresh-cut bunker chunk produces keeper-class stripers when surface fishing is slow. **Large surface plugs:** When large fish are blitzing on bunker at the surface, a 3–4 oz pencil popper worked through the edges of the melee produces explosive strikes. **Heavy bucktail jig:** A 2–3 oz white bucktail with a pork rind or paddle-tail dropped vertically through a suspended school and jigged in the lower water column produces consistently during the run.
Shore Opportunities During the Fall Run
Shore access during the fall run is excellent along the CT coast. **Rocky points and headlands:** Cornfield Point (Old Saybrook), Meigs Point (Madison), Bluff Point (Groton), and the various rocky headlands along the Stonington shore all produce fish during the migration as bass round points in current-swept water. **River mouths:** The Connecticut River mouth at Old Saybrook and the mouth of the Thames River at New London concentrate migrating bass following baitfish into and out of the rivers. Evening and early morning are most productive. **Fishing pressure:** The fall run draws crowd pressure to known spots — arrive early for prime position. Weekday fishing during the peak window often produces more peaceful and more productive sessions than weekends.
