Surfing Waves

Sorry if this in the wrong section.

I happen to live in the Midwest (USA), and there's a lot of lakes, but no ocean. I live on a lake, and was wondering if there's any training things I can do? I know I can swim to build up endurance, maybe paddle around on a paddle board?

I live right next to a beach that allows me to kitesurf lots but only occasionally surf. That said I go out once a week for an hour paddle on my surfboard just to keep my paddle fitness in shape.
