70/40 degree rule

What’s winter is an open question in south Florida.

Without snow and not much cold and lots of greenery all around, the usual standards don’t apply.

That being said, Floridians know winter when they feel it:

  • In the day, if the mercury doesn’t break above 70 – That’s winter!
  • Or during the night, if the mercury doesn’t break 40 – That’s also winter!

Naples airport has recorded 5 days so far this winter that haven’t broken above 70º F.

On average we can count on 17.

We’ve yet to have a single night break below the 40º F mark, however.

That happens about 7 times per year on average.

Our coldest winter of the past 30 years was the winter of 95-96 when 41 days didn’t break above the 70º mark and 17 nights plunged down to 40º or below.

That was an El Nino year by the way.

I wasn’t here at the time, but even if I was, quite frankly I’d have a tough time calling even that winter.

After living in south Florida for 35 years (Wow! Where'd the time go?), I know winter when it happens and I like it just fine that way, thank you very much! When the tourists, snowbirds and new arrivals grouse about snow at Christmas, I remind them that snow is pretty for a couple of hours, then it's a real pain in the you-know-what. I LOVE FLORIDA! Winter weather and all!

Thanks for your comment Constance ... and Hold the Press:

Last night we recorded our first sub 40 degree of the winter!

You must be a Yankee transplant. Below 40 is FRIGGIN COLD to me.

I figure winter starts when the sheepshead strike bait. Maybe there's a whole fishing/seasons/temperature Chart out there somewhere?

Or you could make one!

That's a really good idea, tracking the fish (and what they are doing) is another great way to track the subtleties of the seasons here in Florida.

After reading your addendum, I am not surprised that you went below 40 last night... It was 18 yesterday morning here when we got up --and about 25 this morning... DARN cold --even for the girl who loves winter!!!!!

Have you had an El Nino year since 95-96????

Like Betsy's area, we were below 17 degrees last night! We also have around 8 to 10 inches of the pretty fresh white stuff on the ground because of the snowfall we received yesterday.

Don't get me wrong, I love to visit Florida but I just could not live there and not have the distinct changes of season that mark our year here in the Midwest.

As I've gotten older I have actually come to appreciate the changes even more too. We are many of us are different in our weather "needs," and I'm glad too!

I miss it too. You lose part of yourself when you don't get it, especially the snow.

This year is an El Nino year I believe, could be a cold winter for us. In Orlando I can't remember seeing a 10 day forecast that includes sub-40 (or near sub-40) low temps for 7-8 days into the future like I've seen lately in the news.
