That must not have been too bad of a break. My friend broke his ankle in April and he wasn't cleared to do anything except low risk sports until October. He's lucky he will be able to board this year, but his whole summer/skateboarding season was written off.
I myself have little experience with broken bones, but I would imagine that just like any other injury you just start off easy until you know what you can handle. It would suck if you pushed yourself too hard off the start and ended your season early.
