Our family has been twice in November during Jersey week (First Full Week in Nov). On our first trip was 84 every day and no rain. We swam, wore shorts and tshirts and tank tops during the day and shorts and sweat shirts on a few evenings.
Our second trip during this time was more in the low to mid 70's the entire trip. We started our days off in shorts and sweatshirts, and ended our days with pants and sweatshirts as it was alot cooler in the evenings.
It is a nice time of they year to go, seeing the parks decorated for Halloween and then Christams. I would do it again during this time of the year in a heartbeat.
