When planning a trip to paradise, one of the first things travelers ask about is the weather, and in Key West, the forecast is part of the appeal. With a subtropical climate, warm temperatures year-round, and more sunshine than most of the country, Key West offers an inviting escape in every season. Here’s what you can expect throughout the year to help you plan the perfect island getaway.
Winter (December–February): Sunshine & Peak Season
Winter is one of the most popular times to visit Key West, and for good reason. While most of the U.S. is dealing with cold temperatures, Key West is a ray of sunshine. Average daytime temperatures range from the low to mid-70s, with cooler evenings dipping into the 60s. Humidity is lower, rainfall is minimal, and the skies are typically bright and sunny.
Winter is the premier season for snowbirds and travelers looking to escape colder climates. It’s ideal for sightseeing, biking through Old Town, dining outdoors, and so much more.
Spring (March–May): Warm & Beautiful
Spring in Key West brings slightly warmer temperatures, typically in the upper 70s to mid-80s. The water temperature rises as well, making it an excellent time for snorkeling, diving, and boating excursions. Rainfall remains relatively light, and breezes from the surrounding water help keep things comfortable.
Spring is a sweet spot for many travelers, with gorgeous weather and fabulous beach conditions without the peak winter crowds.
Summer (June–September): Tropical & Vibrant
The weather during summer in Key West is the warmest and most humid time of year. Daytime highs often reach the upper 80s to low 90s. Afternoon rain showers are common, but they’re usually brief. The surrounding ocean keeps the island from getting excessively hot, and the warm water temperatures are perfect for water activities.
Summer is a fantastic season for travelers who prioritize boating, snorkeling, jet skiing, and poolside relaxation. Plus, summer often brings fewer crowds and attractive travel rates.
It’s also worth noting that hurricane season runs from June through November. While direct impacts are relatively rare, it’s wise to monitor forecasts and consider travel insurance during these months.
Fall (October–November): Calm & Comfortable
Fall in Key West offers a quieter, more relaxed atmosphere. Temperatures gradually cool from the upper 80s into the low 80s, and humidity begins to ease. Rainfall decreases as the season progresses, and the island feels a bit more laid-back before winter visitors arrive.
For travelers who prefer a slower pace and beautiful weather without peak-season pricing, fall can be an excellent time to visit.
