I live in Florida. Anything below 65 degrees is cold, and below 50 is freezing.
Up here in Jersey we can go as high as 100 degs. humidity at about 50 to 60% to -2 in winter. And I live about 8 miles from the ocean.
I’ve been in the tropics when the daytime temps hit 70 F (20+ years ago)with cloudy skies. The locals were wearing heavy sweaters and shivering.
Meanwhile, in SW Wisconsin, it has been in the 30s-40s, with a few days hitting 50 and we are loving it. Lower heating costs and more comfort. Very little snow, too. A few rainy days. March weather.
And it’s not a one-off. I’m 77 and this has happened before, just not as often as one would hope.
I heard schools close and work shuts down if the temperature gets below 50 in South Florida. Some people even wear long pants!!!
I was in Key West for the winter of 1986 - 1987. Record cold snap that winter, all the way down to 48. Sears sold out of coats, sweaters, blankets and electric heaters......not that they ever had much of any of that in Key West.
