Spanish Harbor Key (Florida Keys)

Spanish Harbor Key (Spanish Harbor Key / Gulf) is a small Gulf-side lagoon launch in the Lower Keys, known for shallow, flat-water kitesurfing when the wind comes from north through east/southeast sectors. Conditions are commonly described as cloudy, shallow, and flat-to-choppy, so expect a more “lagoon riding” feel than open-water surf dynamics. For wind, the most consistently cited season is the winter-to-spring period: January through May, plus September through December. The spot’s preferred directions are repeatedly listed as north to northeast through east-southeast, including N, NNE, NE, ESE, SE, SSE, and NNW. Typical reported wind speeds for riding are about 15–25 knots, with moderate gustiness that can be more noticeable near old bridge structures and mangrove edges. Safety is the main consideration. The lagoon approach and on-water area can include swimmers, tidal currents, and shoreline hazards such as stones and shells (and additional reports of rocks and concrete). There are also reports of hazards associated with the bridge area (including bridge pilings and power lines), so riders should keep extra distance from the bridge-channel zones and carefully manage the walk from parking to the end of the lagoon. Practically, the launch is described as requiring a several-hundred-yard walk from parking at Mile Marker 35 to the end of the lagoon, which can be manageable for kitesurfing but more cumbersome for foils. Kitesurfing is the best-supported sport; windsurfing and wingfoiling are possible but limited by the shallow/narrow launch and changing depth profile (for wingfoiling, deeper water is reported further out).
