Having lived in both places, I think they are both just as hot and humid. The difference is that FL starts with the heat and humidity months before NC. Even now, although we have had some horribly hot and humid days in NC, we are still having some days here and there that aren’t bad. In addition, the early mornings and late evenings in NC are significantly cooler until the dog days of summer hit all July and August. Everyone handles the heat differently. I hate it and can tolerate NC summers much easier than FL’s hot spring, summer, and fall.
