| Area Forecast Discussion National Weather Service Key West FL 241pm EST Thu Nov 13 2025 Marine Issued at 241pm EST Thu Nov 13 2025 Breezes across the nearshore waters surrounding the Florida Keys slackened this afternoon, but will freshen again overnight. Small Craft Exercise Caution headlines are in effect for all waters except the Florida Bay. Breezes will continue to peak overnight and lull during the morning and afternoon through Saturday. Thereafter, high pressure across the Southeast U.S. will gradually sink across or just north of the Florida Keys. This feature will also weaken such that the coastal waters surrounding the Keys, or at least portions, will become light and variable Sunday and Sunday night. High pressure will then lift northward and gradually strengthen, allowing for a slow freshening of breezes. Issued at 444am EST Thu Nov 13 2025 It has been pleasant overnight going into this early morning for the Florida Keys. KBYX continues to remain shower-free, though Nighttime Microphysics depicts mostly cloudy skies for most of south Florida and the Keys. Temperatures across the island chain are currently near 70F. Observations along the Reef show the overnight surge is ongoing with wind speeds being recorded at 15 to 20 knots. Winds are expected to slightly slacken with Small Craft Should Exercise Caution until Winds Decrease headlines for the Hawk Channel, while the Straits of Florida will remain elevated later into the day. Stable and dry conditions will keep the rain chances at near nil. The remainder of the week's weather across the Florida Keys will continue to be dominated by a post-frontal high pressure in the northeast Gulf. In the wake of this cold front earlier this week, cooler and breezier northeasterly flow has settled over the region, but as the high gradually extends eastward and weakens, winds will ease and temperatures will rebound to more typical for this time of year. Aloft, an upper level ridge over the southeastern US will promote stability and suppress a majority of shower development resulting in mainly dry and mostly sunny conditions. With the high still influencing our current weather, breezes will remain moderate to occasionally fresh in the overnight and morning hours before slackening in the afternoon for the next few days. Daytime highs will climb from the mid 70s back to near 80 by the weekend and an minor uptick in moisture will result in slight rain chances being introduced for late this weekend and into early next week.
