Key West Weather: Monthly Guide & Best Times To Visit

Key West, a tropical paradise, offers a unique climate that varies throughout the year, making it essential to understand the Key West weather by month before planning your visit. The southernmost point of the continental U.S. enjoys warm temperatures and sunshine, but also experiences distinct seasonal variations, impacting everything from your wardrobe choices to the types of activities you can enjoy. This guide provides an in-depth look at what to expect each month, ensuring you're well-prepared for your Key West adventure.

Understanding Key West's Climate: A Seasonal Overview

The weather in Key West is primarily defined by its tropical savanna climate, characterized by warm temperatures year-round and distinct wet and dry seasons. This unique climate is influenced by the surrounding warm waters of the Gulf of Mexico and the Atlantic Ocean, which moderate temperatures, keeping them relatively consistent. Understanding these seasonal patterns is key to planning the perfect trip.

Key West's dry season, typically from November to April, offers the most pleasant Key West weather. During these months, you can expect sunny skies, low humidity, and comfortable temperatures, ideal for outdoor activities. This period is also the peak tourist season, so be prepared for higher prices and more crowded attractions.

Conversely, the wet season, spanning from May to October, brings higher humidity, warmer temperatures, and a greater chance of rainfall. While it can still be enjoyable, the increased humidity can be uncomfortable for some, and afternoon thunderstorms are common. However, the wet season also offers certain advantages, such as lower prices, fewer crowds, and the possibility of experiencing the vibrant tropical flora at its peak.
