Not really as like in Ft Lauderdale, the trade winds keep the humidity pushed out west further. In the summer it is never as hot in FTL or MIA as it is in Orlando, Tampa or even Atlanta.
The ocean is warm year around except Feb and March.
If Miami was a woman, her ass would need to be put to sleep. Andrew Cunning or whatever his name was killed the whole damn city when he shot Vercase. The reality of it is that it is harsh and you are either doing very well for yourself or you are poor. Middle class doesn't seem to exist. Whites and Blacks are the minority down there, even in combined numbers. You wont' be teaching, you will be babysitting.
