I moved to Florida in April. Sold the NJ house. We've owned a house in The Villages since 2019, which is about 20 miles south of Ocala. We bought a 2nd house in The Villages and rent the first one now. It's income positive.
I Lived my first entire summer here in Florida this year. The heat is a big nothing burger. Yeah, it's hot, it's just as hot in July in NJ. You just don't do outside stuff, from like 1 to 5pm. You can, but it's got to be in short doses.
Besides, you go from a house with AC to a car with AC to a place with AC, rinse repeat.
The difference is that summer runs from April to mid October.
Right now, it's very pleasant. Highs in the high 70s, lows in the low 60s. Yes, you get the occasional cold snap, where it struggles to get into the 60s, and every once in a while, it gets into the 30s.
I've already lost my tolerance for cold though. 50s was Tshirt weather in NJ. Down here, I'm bundled up like Nanook of the North when it's in the 60s.
