NWS Marine Forecast


   GMZ005-261000-  Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas  454 PM EST Wed Feb 25 2026      .SYNOPSIS...  An Atlantic ridge reaching westward across the Florida Peninsula  will pull further eastward and away from our area over the next  couple of days. As a result, breezes will gradually shift further  east and south of east. Winds will vary quite a bit due to an  ongoing land breeze and cold nearshore water temperatures. The  western flank of the ridge will lift northward into tonight and  will generally help to freshen breezes as they shift east  southeasterly. Nearshore waters will likely remain a notch or two  lower due to still cool waters. Thereafter, winds will be light to  gentle northeast to easterly due to the general higher pressure  over the eastern United States and lower pressure to our south.    The Approximate Shoreward Edge of the Gulf Stream as of February  17...    7 NM South of Dry Tortugas Light...on Loggerhead Key.  3 NM South of Cosgrove Shoal Light...off the Marquesas Keys.  2 NM South of Sand Key Light...off Key West.  7 NM South of Looe Key...off Big Pine Key.  11 NM Southeast of Sombrero Key Light...off Marathon.  14 NM Southeast of Alligator Reef Light...off Islamorada.  7 NM Southeast of Molasses Reef Light...off Key Largo.  3 NM Southeast of Carysfort Reef Light...off Ocean Reef.    Gulf Stream Information Courtesy of the National Weather Service in  Key West based on products from NASA SPoRT and RTOFS.    $$
