Potential Weather Considerations in January

While January is generally beautiful, it's wise to be aware of a few potential weather-related factors:

Cold Fronts

Occasionally, cold fronts can sweep down from the mainland United States, bringing cooler temperatures to Key West. These fronts can cause temperatures to drop into the 50s (10-15°C) for a few days, accompanied by stronger winds and higher wave action. It's always a good idea to check the forecast closer to your travel dates.

Wind Conditions

The northeasterly or northwesterly winds that are common in January can sometimes be brisk. This can make the ocean feel choppier and cooler than the air temperature might suggest. For those sensitive to the wind, seeking sheltered spots on the beach or enjoying activities on the leeward side of the island can be beneficial. — North Crowley Football: Panthers' Legacy & Future

Rainfall

January offers a unique sweet spot for Key West visitors. Unlike the hotter, more humid summer months (June-August), January provides a respite from extreme heat. Compared to the late fall (October-November), which can still see tropical storm activity, January is much more predictable and stable weather-wise.
