DEFINITELY prepare for warm and cold in February. Us FL natives can't seem to tell right now if it will be definitively cold or warm through to April.

i bet your idea of cold is 60 degrees
Nah... I grew up in NY... The thing is people expect it to be warm down here all the time, so when it's cold, it really feels cold. Though it may not be as bad as.. let's say... 15* weather.
