    Yes this is true. I was in The Bahamas all of last winter ans it was FREEZING all thru January and February. On the mainland in South Florida it went down to 32f/0c and was extremely cold during January/February with tempuratures far ( wildly ) below seasonal norms for an extended period of time.
