Around September....Maybe August...I just start feeling BLAAAH. We also have the humidity which REALLY sucks. It's why me and my Wife would love to move to North Georgia some day. They are often a full two months ahead of us in cooling down. But ya never know here in North Florida. About 14 years ago, we had 5 freezes in October???? UNHEARD OF! Christmas 1982, I got a sun burn. Christmas 1983, it was so cold, several people on our block had busted pipes. That year, it was frigid from a week before Christmas till a week into January.....I remember that well because it was FREEEEZING here in Jax the same day our Rams got smoked 51 to 7 in DC.
