People winter in Florida, as in the verb.
We call them snow birds.
To them, without a doubt …
Winter the noun does not exist in south Florida.
Major caveat: To us “year rounders” the thermometer couldn’t be more clear. We go by the 70 degree rule. What is the 70 degree rule? You know it’s a cold day in Florida when the daytime high doesn’t rise above 70° F. We call those day “winter.” On the other side of the coin, you know its a hot day in Florida when the nighttime low doesn’t drop below 70° F. Going by the 70 degree rule, Naples averages 18 days of winter and 130 days of summer. As for the rest of the days, us “year rounders” call those spring and fall; or in the parlance of the northerners, “– that’s ridiculous, it’s all summer!” Well, not if you’re a Florida weather connoisseur.
