We went at Thanksgiving in 2008 and I have to warn you, be prepared for anything and check the weather forecasts right up until the day you leave to get a better idea of what to take. We froze our tushies off a few days (during the day, not to mention the nights!) and wore long johns under our clothes and gloves and coats and hats--it was in the 30s and 40s. A few days it was more mild and we wore sweatsuits and/or sweatshirts and jeans. We did not wear shorts at all on this trip. On one day it got into the 70s and my daughter swam, but it was too cold for me. It was not humid to me in November, but then again I lived in Houston for nine years (I swear the air is wet there) and still live in hot humid Texas, so I am probably a lot more tolerant to the humidity than I am to the cold. Hope that helps.
