During the winter I would go Mountain Biking in Jonathan Dickinson state park all the time during the weekdays. On weekends I would just ride my bike down the roads to see wild life since the mountain biking trails got filled up with weekend warriors.
Fishing is nice too. Even if you don't have a boat. I use a cane pole to fish the canals behind my house and end up catching tons of Oscar and Tilapia with 5$ of worms from Wal Mart. If you're up for dropping money, getting a fishing bow can be REALLY fun for catching armored catfish. They cause a ton of property damage and are bad for the environment so no one will care if you hit them.
Aside from that, during the summer I would kayak the Loxahatchee, find a pool to hang out in or just hit the beach to bodyboard, surfboard, or handplane. If you have a good group to go with, pitching in for a road trip to the springs in Ocala is the best way to escape the heat. Plus, most of the camp grounds up there have A/C cabins if you're done with tents and 90 degree nights.
I honestly miss Florida. Aside from gas, it was so cheap to go out and have fun.
