Navigating Potential Weather Quirks

Our experience: We've seen instances where a quick sweater or even a light windbreaker was welcome during these periods. It's always good practice to pack layers, even in the Florida Keys.

Wind Conditions

Key West can be a bit breezy in January. The trade winds that typically blow from the northeast can pick up, especially on the Atlantic side of the island. While these winds can be refreshing and help keep humidity low, they can also make the air feel cooler than the actual temperature suggests.

Tip: If you're sensitive to wind, consider spending more time on the Gulf side of the island, which tends to be more sheltered.
