Hi
All those zones record is the "average" low over a set period of time. I'm supposedly in 10 A but over the years have been as low as 8 and as high as 11 Who knows what this winter will be or the next etc etc.
They're just averages anyway. gary

Wow Gary! Its stunning that a zone 10 would ever drop into the teens. Where in Florida are you?

I started doing that yesterday but it takes a while. Was kinda hoping another site like USDA or soemthing would already have it on a list or soemthing. But I guess not. And yeah I know. I just want to see what the actual average is, and how often we have colder or warmer winters.

It all depends on the jet stream. If it dips south we can get very cold though for a short time. .Coldest I've experienced was 25 for almost 6 hours while 10 miles west of me was 10 degrees colder. Will never forget the snow of 78 lol Can get cold as early as Oct and as late as march. but is VERY unusal . Right now we are experiencing a cold spell due to Sandy think we might hit 48 today which would be a record. I live very close to the gulf stream so highs and lows are moderated a lot lol
I always predict that it will be either above or below average lol have never been wrong yet!!! lol gary
