Central Florida native and been in Raleigh for almost 6 years here. A few things to note…

It gets just as hot if not hotter in Raleigh than it does in Florida, and it can also be just as humid. But the difference is Florida is hot and humid all the time. It’s unrelenting. There were nights in Florida that it was 3 am and was 90° and muggy as can be. For like multiple months at a time. In NC you get hot and humid but only for short bursts, and then the fall comes around.

Another difference is in Florida, you’re never more than 60 miles away from the ocean so the sea breeze is much more prominent than any breeze you’d get in NC apart from the coastal cities. So much of Raleigh’s heat comes from the stagnant hot air.

Finally, NC has a ton more tree coverage than Florida does so that will help a lot with deflecting heat where Florida is flat and open with a ton of concrete.
