For me, the big thing I've noticed is when we DO get chilly, over the past decade we tend to transition back to the warm subtropical ridge-regime at very fast speed. I could swear it never used to be like that in December-February. A cold front would pass, we'd get a night or two of chilly temps, and then it would be a slow transition back to seasonal warmth, like high temps in the upper 70s, lows in the mid 60s.
These days, fronts pass, we barely break 60 here in Miami to begin with, and almost immediately, a subtropical ridge regains control, bringing temps and humidity levels that never really were the norm for us in winter. AC wasn't nearly as necessary December-February as it is now.
I have no science to back it up, but I am guessing that at least for the urban core of Miami, we've passed a tipping point with the urban heat island effect, where it's just not going to be able to stay cool here unless we get some historic storm system like January 2010.
