We will be arriving on 2/1 as well! It will be our first Feb trip so I'm no expert. We've been in December 3 times. The first time we were in shorts and tee shirts, swiming every day and hot and sweaty (this was 12/27 - 1/3) the next year (12/24 - 1/1) we were freezing and buying everyone hats, gloves and scarves. The year after that (12/3 - 12/11) we had some days where we were in shorts, some days in jeans and sweatshirts but didn't need anything more than a light jacket. I think February will be the same way...it can go either way. Average temps are lows in the 50s, highs of about 70 - 72. Probably best to watch the forecast closely right before you leave and then pack a little of everything to be able to layer as best you can.
