Yellowfin tuna fishing out of Captree is a September and October fishery, run offshore from the port on Long Island’s South Shore. This guide covers the season, the run, the named reefs near the port with their depths, how the fish are worked, and who fishes them. It helps you decide where to look and does not promise fish.
When yellowfin are around Captree
Yellowfin are around Captree in September and October. Those two months are the window, but the fish follow the water rather than the calendar, so conditions inside the window decide where they are on any given day.
For other tuna species and seasons, see our tuna guides. In September and October, read the ocean data closely before you decide where to run.
Where Captree boats run for yellowfin
Offshore tuna trips leave Captree and head out to the ocean through Fire Island Inlet.
The water on the day sets where the boats stop; there is no fixed spot. If you run your own boat, plan the same way and let temperature breaks and color changes pick the ground. The Northeast yellowfin guide (see also the Atlantic Northeast region guide) covers the offshore grounds at regional scale.

Offshore trips from the port
Trips run offshore through Fire Island Inlet. The plan is built around the window and the water, so each morning starts with what the ocean data shows. For methods and the species picture, see our yellowfin tuna guide.
