I don't know the exact temp. but we were there 1-07-02 and it was miserable. The wind was piercing cold. Too cold to swim. We kept our sweats on. There was a storm the next day so we couldn't go to Castaway Cay. Ended up going to Freeport and then to Castaway Cay. That was the only warm day. I bet it was even cooler than 65. It was the same time that Florida had their highs in the 40s.
