Special Weather Statement issued January 26 at 3:36PM EST by NWS Miami FL

Effective: Mon January 26, 2026, 3:36 PM
Expires: Tue January 27, 2026, 7:00 AM

An Arctic cold front is forecast to move through South Florida early next weekend bringing the potential for the coldest air the region has experienced since January 2010. This cold blast could last into the early portion of next week. While the exact details remain uncertain at this time, there is the potential for lows to drop down into the 30s across a good portion of the region and even into the 20s west of Lake Okeechobee. When the wind is factored in, the wind chill values have the potential to be colder than the actual low temperatures during this time frame. Residents and visitors to South Florida should continue to monitor the latest forecast from NWS Miami throughout the week on the possible cold to frigid temperatures.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
