Alligator Reef Light

Alligator Reef Light is a boat-access-only reef-lighthouse spot off Islamorada in the Florida Keys. The area is inside the Florida Keys National Marine Sanctuary, with crystal-clear water and shallow reef sections around the lighthouse base. Water depth is reported around roughly 4 to 10 feet at the buoys, with deeper ocean surrounding the reef. For kitesurfing, the spot is described as a boat-launch kite location over medium-wave conditions, with riders typically working the waters around the historic lighthouse. Because there is no dry land and self-rescue to shore isn’t possible, sessions require boat support and careful planning. Mooring buoys around the lighthouse base are first-come, and public access to the lighthouse structure itself is not permitted. Wind is centered on prevailing easterly trade winds, with typical ranges around 15–25 knots. Winter and spring are highlighted as the most reliable periods, while cold fronts can knock out a few days at a time—so conditions should be checked day-of. Regional thermal reinforcement is described as an afternoon sea-breeze effect (peaking late afternoon) during late spring through early fall, but use forecasts to confirm it for the specific session. Safety-wise, the main concerns are shallow coral hazards, strong currents, and isolation combined with boat traffic and other marine users (snorkel/dive boats). Practical local guidance emphasizes not going alone, using a boat and designated rescue plan, and keeping safe distances from other vessels around the lighthouse base. Emergency guidance points to Coast Guard response as the nearest emergency responder, with 911 as the emergency number.
