When white marlin are off Shinnecock

White marlin fishing out of Shinnecock runs from late June through September, with the best fishing from July through September. The jump-off point is Shinnecock Inlet, and the Shinnecock port guide covers the inlet, ramps and forecast sources. This guide covers the season window, the named grounds off the inlet, how the local charter fishes and where the rules live. It points you to a better place and time to look, and it doesn’t promise fish.
The season window
Sea Venture runs its marlin line from late June through September, with the best fishing July through September. The line isn’t split by species, so the window covers all marlin, white marlin included. For behavior and biology, see the white marlin species guide.
Use the window to pick your trip weeks:
- Late June: the start of marlin season on the Sea Venture line.
- July through September: the stretch Sea Venture lists as best.
- After September: outside the window Sea Venture gives for marlin.
Where boats run from Shinnecock Inlet

The inshore reefs sit between 2 and 12 nm of the inlet, with the named offshore grounds beyond them. Marlin move with the water, so treat these grounds as reference points rather than places where fish will be.
| Ground | Depth | Distance |
|---|---|---|
| Shinnecock Reef | 76-84 ft | 2.0 nm south of Shinnecock Inlet |
| Twelve Mile Reef | 123-143 ft | 12.0 nm from Moriches and Shinnecock Inlets |
| The Dip | – | – |
| Coimbra | – | – |
| Hudson Canyon (shelf edge) | – | – |
The depth and distance figures for the two reefs come from New York’s artificial reef locations.
Shinnecock Reef
Shinnecock Reef sits in 76-84 ft, 2.0 nm south of Shinnecock Inlet. It is the closest named structure to the inlet.
Twelve Mile Reef
Twelve Mile Reef sits in 123-143 ft, 12.0 nm from Moriches and Shinnecock Inlets. Since the distance is measured from both inlets, it also works as a shared reference if you are comparing jump-off points.
The Dip and Coimbra
The Dip and Coimbra are offshore grounds that boats run to from Shinnecock. This offshore structure is shared across Northeast ports, and the Northeast white marlin guide (see also the Atlantic Northeast region guide) covers the regional picture.
Hudson Canyon
Hudson Canyon is the shelf edge and the farthest of the named grounds. Work out the run to The Dip, Coimbra and Hudson Canyon on your own chart, using your boat’s fuel burn and reserve. Chart Contours shows the shelf edge near Hudson Canyon, though chart layers are not for navigation.
