The Florida Keys, a string of tropical islands stretching about 120 miles off the southern tip of Florida, offer a year-round paradise for visitors. However, the best time to visit depends on your preferences, budget, and the activities you’re interested in. Let’s explore the different seasons in the Keys to help you plan your perfect getaway.

Winter: December To February

Winter is the peak tourist season in the Florida Keys, and for good reason. The weather is near perfect, with average temperatures ranging from the mid-60s to mid-70s Fahrenheit (18-24°C). The humidity is low, and there’s very little rainfall. The water is more relaxed but still comfortable for swimming and water activities.

Pros:

Ideal weather for outdoor activities
It is the perfect time for fishing, especially for sailfish and kingfish
Great for snorkeling and diving due to clear waters

Cons:

Highest prices for accommodations and flights
Crowded attractions and beaches
You need to book well in advance

Winter is perfect for those who want to escape cold weather and enjoy outdoor activities. However, be prepared for higher costs and larger crowds.

Spring: March To May

Spring in the Florida Keys offers warm temperatures and low humidity. Average temperatures range from the mid-70s to 80s Fahrenheit (24-28°C). The water starts to warm up, making it more inviting for swimming and water sports.

Pros:

Warm but not hot temperatures
Fewer crowds than in winter, especially after spring break
Good time for water activities and fishing

Cons:

Spring break (usually in March) can bring crowds and higher prices
Some afternoon showers, especially in May

Spring is an excellent time to visit if you want to avoid the winter crowds but enjoy warm weather. April, in particular, offers a sweet spot of good weather and smaller crowds.

Summer: June To August

Summer in the Keys is hot and humid, with temperatures often reaching the 90s Fahrenheit (32-35°C). It’s also the start of hurricane season, from June to November. However, this season offers its unique charms.

Lower prices on accommodations
It is a good time for diving, as many fish species are more active
Lobster season starts in August

Summer can be a great time to visit if you’re on a budget and don’t mind the heat. The warm waters are perfect for snorkeling and diving, and you can enjoy the start of lobster season in August.

Fall: September To November

Fall is considered the off-season in the Florida Keys. The weather starts to cool down slightly, but it’s still warm, with temperatures in the 80s Fahrenheit (27-32°C). Hurricane season is still in effect, with September being the peak month.

Pros:

Lowest prices of the year
Fewer crowds
It is still warm enough for beach and water activities
It is an excellent time for fishing, especially for bonefish and tarpon

Cons:

Highest chance of hurricanes or tropical storms
