| Area Forecast Discussion National Weather Service Key West FL 1240pm EST Sat Dec 27 2025 Issued at 1111am EST Sat Dec 27 2025 The Florida Keys are enjoying another pleasant day under the sun! Skies are mostly cloud free according to GOES-19 visible satellite imagery. Temperatures across the island chain are in the lower to mid 70s with dew points in the mid 60s, meaning conditions outside should feel nice and comfortable! Overnight, there was a slight surge in breezes as a nocturnal land breeze from the mainland moved through. Those gentle to moderate breezes have started to return to light to gentle already as Reef observation sites indicate winds are northeast at around 10 knots. As weak high pressure continues to sit in the Gulf, our weather will continue to be similar to the last few days; near nil rain chances, and light to gentle breezes. Therefore, no changes were necessary to this update. .FORECAST... Issued at 454am EST Sat Dec 27 2025 Weak high pressure is expected to meander across the eastern Gulf for the next few days. Since the high is expected to maintain its strength, there may be bouts of gentle to moderate nocturnal land breezes over the next few nights. Plenty of dry air will remain entrenched across the Keys for the next several forecast periods resulting in nil rain chances through Monday night. As we approach the final couple days of 2025, a healthy cold front is expected to move southeastward. However, before the front gets here, there may be a period early Monday to early Tuesday where breezes become light and variable. If this occurs, radiational cooling may take place which may allow temperatures to fall to the lower 60s, even near 60 degrees, especially on the larger islands of the Keys. The healthy cold front mentioned previously is expected to swing through the Keys sometime Tuesday/early Tuesday evening. This will result in freshening northerly breezes. Therefore, a period of breezy conditions are anticipated for Tuesday night through New Years Eve morning. While breezes diminish slightly New Years Eve, we expect gentle to moderate breezes to continue through the first few days of 2026. Some moisture pooling ahead of the front will result in slight chances of rain (20%) Tuesday. Near nil rain chances are expected thereafter as drier infiltrates the Keys in the wake of the front. Marine Issued at 1111am EST Sat Dec 27 2025 No watches, warnings, or advisories are currently in the effect for the Florida Keys waters. From synopsis, weak high pressure will meander in the eastern Gulf over the next few days, resulting in light to gentle breezes. Mainland nocturnal land breezes may drive brief bouts of gentle to moderate northerlies in the morning. A healthy cold front is expected to move through the Keys towards the middle part of next week. This will lead to freshening northerly breezes throughout all the Florida Keys coastal waters. NOAA Key West FL Office: Watches - Warnings - Advisories FL...None. GM...None. |
