We've been 4 times the first week in January. Three of the four, it was freezing at night, and cold during the day, never even wore shorts! This past January, 80's in the daytime and upper 50's at night, much better. The kids swam at the pool, but we didn't venture to a water park, too cold for us. Was just down the first few days of April and it was too cold for swimming to me. The days were in the 70's but very windy.
