We see Canadians in shorts and tee shirts in Florida when it’s 50 degrees. They’re also the only ones who will stay for an extended time in the “hot springs” which are only about 70 degrees.
It’s all what you’re used to.
We were in PR in March a few years back. When we flew out of CO, there was snow. Happened that there was a bit of a cold snap while we were visiting; they got into the high 70s. People I was working with were wearing winter coats.
We were in heaven.
