FAQs Regarding the Best Time of Year to Vacation in the Florida Keys

What is the best month to visit the Florida Keys for 2026? For the absolute best balance, May 2026 is the top recommendation. You’ll enjoy calm 82°F waters and warm breezes, avoiding the peak winter crowds of January and the late-summer humidity. It is also the perfect time for events like the Key West Paddle Classic (May 9).

When is the cheapest time to visit the Florida Keys? The most budget-friendly window is September through early November. During this off-peak period, luxury rentals in Marathon and Key Largo often see price drops of 30–40% compared to the winter peak.

Is it too cold to swim in the Florida Keys during winter? Not at all. Even in January and February, the water temperature rarely dips below 70°F. This makes it the premier winter destination in the continental U.S. for snorkeling and diving.

When is the 7 Mile Bridge Run in 2026? The iconic 7 Mile Bridge Run is scheduled for April 11, 2026. If you are planning to participate or watch, we recommend booking your Marathon vacation rental at least 6 months in advance.
