About the Greenwich Harbor

Greenwich Harbor sits at the far western corner of Long Island Sound, where the shoreline turns and the Sound narrows toward the East River. The gauge at Grass Island reads tidal elevation at the harbor mouth. What matters to anglers is what lies immediately outside it: a scattered chain of low rocky islands, reefs and shoals running east and south from the harbor, including Great Captain Island, Little Captain and a series of unnamed rock piles that break the tide into rips.

The tidal range here is larger than most of the Connecticut coast, and the water moves hard around the rocks. That current is the fishery. Bait gets pushed against the structure on both stages of the tide, and striped bass and bluefish set up downcurrent of the reefs to feed on it. The rips are fishable from small boats on most days, though they can turn unpleasant quickly when wind opposes tide.

Striped bass are present from April through December and include some genuinely large fish, particularly at night around the outer rocks. Bluefish arrive in June and stay into the fall. Tautog are a serious local fishery on the rock piles in spring and again from October into December, and black sea bass have become steadily more common over the past two decades. Summer flounder work the sand patches between the islands.

The harbor itself offers town launches and moorings, and the outer islands are close enough that the run is short. This is boat and kayak water for the most part, with limited but real shore access along the harbor edge.

This is the most heavily boated corner of the Sound in summer, and the outer islands see substantial recreational traffic on weekends. Early mornings, weekdays and night tides are worth the effort for that reason alone. Great Captain Island has seasonal restrictions on landing, so check current town rules before planning to fish it from shore.

This water needs a real photo

The photo at the top of this page is not Greenwich Harbor.

It is a regional stand-in, honestly captioned but generic — we will not put a name to a river we cannot prove. Send us a photograph you took here and it replaces the stand-in, with your credit on it.
