Weather has its little freaks all the time. I've seen frost warnings in Orlando in October and when we were in Fort Lauderdale in both November 2010 and back in January of this year, bottom line is all I wanted to wear was shorts and t-shirts. With all due respect, it says you are from Oakville, Ontario, CANADA! It's a LOT warmer that far south compared to here! Leave your winter jacket and snow pants home for sure
-27C here today, feels like -37C with the wind chill. I want to move to Fort Lauderdale
Seriousley, you are going to experience such a drastic change in temperature, what local southern people call cool or cold you are going to still feel warmer than they do. You're more climitized to the cold.
