Coastal Waters Forecast for the Florida Keys
National Weather Service Key West FL
High pressure centered over the central Gulf will slide eastward through the rest of the work week. Light to gentle breezes will respond, veering from the northeast to east tonight to the southeast by Thursday. A second, stronger high will build in the western North Atlantic and interact with a developing area of low pressure in the central United States, supporting freshening southeasterly breezes for Friday night through early Sunday. As the front approaches the Keys marine zones late Sunday, breezes will once again briefly slacken.
Florida Bay, Hawk Channel and Straits of Florida from Ocean Reef to south of Dry Tortugas, and the extreme southeastern Gulf of America, including The Florida Keys National Marine Sanctuary Seas are given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. Wave Detail will include details about the period and direction of origin for the highest energy waves. Long-period swells coming from a different direction than the wind would be included in the Wave Detail.
