Greenport Jetty (Southold)

Greenport Jetty (Southold) is a small, flat-water kitesurfing spot with clean water, where the jetty extends several hundred feet toward Shelter Island. The sheltered water inside the jetty is a key draw for freeride and freestyle, but the environment is technically demanding because of the spot’s proximity to ferry access and commercial shipping lanes. Wind is most favorable from the southwest through west (SW, WSW, and W). Spot-level details indicate a gradient wind regime with moderate reliability and light gusts, and typical winds are in the range of about 15 to 25 knots. Regional thermal sea-breeze influence can support afternoon sessions, commonly filling between roughly 1:00 PM and 5:00 PM during late spring and summer (May through September). Safety is the defining constraint here. Hazards include ships and frequent ferry traffic, along with jetty rocks, strong tidal currents in the channel, and a narrow riding area. Riders should avoid ferry lanes and stay clear of the commercial docks at all costs, and local fishermen on the jetty are part of the practical on-site guidance system—asking them for directions is strongly advised. Because the current is powerful, be prepared for significant drift if the wind drops; timing transitions around the ferry schedule can reduce risk. Water temperatures are warmest in mid-summer and remain rideable into autumn with proper wetsuit protection. Spot reports highlight kiting from late June through mid-to-late October as a realistic season window with wetsuit use, and the warmest months are July and August. Expect crowded conditions on land in peak summer, while the water can be less busy due to the difficulty level.
