The first year we ever went at this time of the year ( before I had heard about these boards of course ) it was stunning weather 80's no less. We thought that was the norm so the following year we took shorts etc and it was so cold that everywhere had sold out of hats, scarves etc and we were freezing. Since then we have been many times, and each year is different. There is no predicting. One time as we arrived at Orlando airport we were greeted with returning travellers who said that they had been basking in sunshine, but that the weather forecast said that the weather was changing and that from the next day it would be freezing every day, and how right they were!
