What kinds of things are there to do in Miami alone?

I just moved to Miami by myself from the northeast and I don't know anyone down here. I have a little while before school and work start, so I'm looking for things to do solo until I meet some people. Also, I'm on a budget, so low cost activities are appreciated.What kinds of things are there to do in Miami alone?
