Average high temperatures settle in the low 80s Fahrenheit (high 20s Celsius), while average lows hover around the low 70s Fahrenheit (low 20s Celsius). Sea surface temperatures also begin to cool, though they usually remain comfortable for swimming.
This shift in climate makes November an attractive time to visit Key West. The decreased precipitation and humidity offer more comfortable conditions for outdoor activities, from exploring the historic Old Town to enjoying watersports. The reduced likelihood of hurricanes further contributes to the appeal of this month. Historically, November marks the end of the peak hurricane season, creating a safer and more predictable travel window. This combination of favorable weather and fewer crowds compared to the peak winter season presents distinct advantages for travelers.
