I really don't mind at any time of year to go. But have to tell you that December 2009 (8-14), was very interesting in Central Florida. Summertime in December with thick fog overnight through mid-morning near the end of my trip.
In fact, I believe the last 80-plus-degree day for 2009 was on the day before I left because, as well all know, January 2010 was frigid and and snowy, which is a rarity.
It was strange, though, for me arriving in Orlando and the high was 64 and cloudy, a little windy. Although I was in a sweater and pants, strange to see locals in winter coats, hats and mittens. It was fun getting ready for the Christmas party, though - shorts, shirt, flip-flops, a santa cap, and a BIG BULKY WOOL HOLIDAY SWEATER. It was around 82, cloudy, with 70-80-percent humidity. Perspired a little, but was awesome. Twelve days before Christmas. It was fun.
The same thing can be said when I visited Disneyland a few weeks ago in early October, five days after record highs of 111 in Los Angeles and Anaheim, I was walking around in 65-degree rain in shorts and a sweatshirt in near record-cold. Felt fine, but should have brought a thicker sweater.
I didn't mind in both instances because I was on vacation and took it in stride. I guess being a life-long northerner that has experienced year after year of four seasons, and spendind 4 years in Alaska on an assignment, I have learned to adapt.
I just wonder what it would be like living in Orlando and SoCal 24-7.
