You're too late for that, the North West Florida Coast or what some call the "forgotten coast" has some days that reach 70 but at night can get down right cold. After a cold front moves in you might have a day or two in the 50's as the high but then starts to gradually warm back up into the 70's until the next cold front rows in. That would be your best bet. It's actually the best time to go if you ask me, the water is clear and the beaches are basically clean and bare. It's also the best time to eat Apalachicola oysters too!!
