Coastal Waters Forecast for the Florida Keys
National Weather Service Key West FL
An elongated weak area of low pressure east of the Florida First Coast will continue to pull away this afternoon. This will result in light to gentle south to southwest breezes. Light and variable breezes overnight, coupled by cool water temperatures, will support a potential marine fog event overnight through at least Sunday morning. A cold front is expected to push through the Keys coastal waters Sunday night and Monday, resulting in freshening north to northeasterly breezes. Breezes will modestly slacken Monday night and Tuesday, before another more potent cold front pushes through the Keys Tuesday night or Wednesday, bringing a stronger surge of north to northeast breezes.
Florida Bay, Hawk Channel and Straits of Florida from Ocean Reef to south of Dry Tortugas, and the extreme southeastern Gulf of Mexico, 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.
