I moved to Florida from the northeast about 25 years ago, by choice. I just like the water, fishing, boating, scuba, etc. I am in the South Miami area.
It was fun the first year going to the beach on New Years Day and calling my parents up north that I was swimming in the ocean. But after about a year, I realized that no sane Floridian would go to the beach in January with water temperatures down to the mid-70's (23-25 C.). That is considered temperatures for tourists ... lol.
It certainly is hot and humid by many standards but if I was moving to Florida, the only place I would go would be the lower southeast side, or the Keys if I could afford it. With the Gulf stream just a few miles off the coast and an ocean breeze, the temperature is very stable as long as you are near the ocean. There is even debate as to the highest temperature ever reached here. Based on where the temperature was taken (airport or downtown), it is argued that Miami has never reached 100 F. Just 98 F. But if you go inland (Orlando) or further north (Jacksonville) then you will melt. And you will melt even quicker on the Gulf side of the state and the panhandle area.
I have been to California, Oregon, Washington, BC, and other Pacific areas but for me the water is just too cold. I would like to go to Hawaii but from what I hear it is very expensive. The Gulf states, Texas, Louisiana, Mississippi, Alabama and the and the west coast of Florida are just WAY too hot and humid in the summer.
I will stay here in South Florida. It is expensive by many standards but I still like to cook on the patio wearing a T shirt and flip flops in the winter.
