As others said, this is the hardest time to pack for. I have no problem packing for any of my other trips (late Spring/late Summer and October), but when it comes to packing for my late January/early February trip....yikes. One trip it was so cold, I had to wash my sweats a couple of times to have something to wear. I've never been able to swim during this trip. Last year, not only did I go late January and had to pack for that variety of weather, we also went on the cruise, so had to pack for that trip too! Sweatshirts, long sleeve tee shirts, sweatpants, socks, gloves, hat are all a must for this trip. I don't bring the misterfan on this trip. One year, not only was it cold, but it rained for days and it was a cold miserable rain, so the rain gear is a must to pack. Also laundry detergent. Even if I make it to my shorts during the day, my sweatshirt shows up as soon as the sun starts to set. We will also be there the same time as the OP, Jan. 17-24 @ BWV.
