Fulltime weather calendar?

We stayed in north Florida our first year, half dozen nights in the 20's. No problem warmed up to the low-mid 50's. Being from Northern Illinois we have seen that in lat Sept. While in FL, Texas was having a rough winter but we decided to give Austin area a try the following year. We had similar weather to the previous winter in Fl. Back to Fl in '12', Ok south Fl, our low was like 48 degrees sure the natives suffered but we loved it going back this year.
Weather is like the stock market, previous results do not predict future gains.
