Yeah, April is the better time. Guaranteed great, toasty warm weather. Beware! If you re not familiar with the intensity of the tropical sun during April in Key West, it will surprise you. Pale tourists come down here in the middle of January, sit in the sun for a couple of hours with no protection, and wonder why they re burnt and peeling. Please be especially careful of our sun in April. Enjoy your visit!
april after spring break and snowbirds return northYou have a small window of time brfore realy hot weather hit in mayso from mid april to mid mayPrices tend to be better in the keys by end of AprilBe sure tovisit DryTortegas and take a ride north on US1 to Bahia Honda state parkIt s worth the trip
February is better weather the only down side is that the weather is not warm enough for snorkeling. Going to the Dry Tortugas as someone else suggested is a great idea for snorkeling.
april can be rainy i would go in feb. it is never too cold in the keys. i can lay by the pool in 70 degree weather
Less likely to have a cold snap (low of 65 or so) in April.
weather will be better in April, but also more crowds due to spring break
