One of my best road trips ever was flying into Miami and renting a car and going down the Florida Keys. The water is 2 different color blues on each side of the highway and to be in a car with the tunes blaring on this little strip of highway, it was awesome. Key West has the best sunsets in the US.
Go and enjoy yourself.
In Florida, since it is tropical, it may rain a tiny shower for a couple of minutes and that_s it for the day. Occasionally I_ve seen showers that last less than a minute. The tropics are weird like that.lol
I wouldn_t worry much about hurricanes. Just keep an eye on the weather channel and listen to see if any storms are developing. They develop over by Africa so it takes a long time before it is anywhere near Florida.
If you go to Miami, I recommend staying around the beach. If you do want to leave, Then going somewhere like Coconut Grove _coco walk_ is nice. Also In Coral Gables_ _miracle mile_ is also nice. Coconut Grove and Coral Gables are very small cities within Miami.
The keys..the hot spot is Duval street.
Hope this answered your question. Have fun.
