KEY MESSAGES

-Light to gentle breezes will prevail through the next few days before a cold front early next week.

-Near seasonable temperatures and a mainly dry pattern are expected to continue through the weekend along with near seasonable humidity levels.

-The next, healthy cold front is forecast to push through the Florida Keys early next week. This will result in near nil rain chances, drop in humidity, and a period of below normal temperatures for the last day of 2025 and the first couple of days of the New Year 2026.

AVIATION

(18Z TAFS) Issued at 1236 PM EST Sat Dec 27 2025 VFR conditions will prevail at both EYW and MTH through the TAF period. Dry air will limit any shower development for the day. Near surface winds will continue to be light and variable through this evening.

FORECAST

Issued at 454 AM 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 1111 AM 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.
