I've gone the past 6 years in early December. Three of the years were great (1998, 1999, 2001), high 70's/low 80's most of the week, wore shorts. One year was cold (2000), low 60's the entire week, the other 2 years (2002, 2003) it was a mix. 2002 was the only year we had rain, we had 2 days of solid rain. The rest, little or no rain. Last year I was glad I brought a light winter coat & gloves, some evenings got cold.
