I just moved down to Miami last month. I know it's going to be brutal come May/June (I was just down there in August) but I've spent the last 38 years in the North East and having to put on a winter jacket and gloves just to sit in your car and drive somewhere while waiting for the heater to work gets old after a while. At least a lot of the places in the South (or at least the newer cities in Florida) are built for the heat, meanwhile the NE wasn't built for recent climate change. This summer was just as bad as Miami many days in a row, I was staying at my parents 100+ year old house in NJ (which doesn't have central air) and even with the window AC cranked down to 63 I'd wake up sweating because it was 80-90% humidity in my room.
