We went several times in January 2006. The weather was nice, but there's no way of knowing what it will be. I've been a lot during the winter months. The weather can run the gamut of being beautiful and warm to raw and bitter. The kids and I went down the first week of March one year. It was in the high 60's, but BB was open. Besides us, there were MAYBE four other customers there. It was fine when we were in the water, but once out - BRRRR! The kids still loved it.
