I'd have two homes:

May-Sept (Summer) - Yankton, South Dakota, Hobie Beach on Lewis & Clark Lake. Big, deep lake, no wet suit needed, a beach for beachcats only, cheap camping and during the week there is practically no one on the lake.

Sept - May (Winter) Lake Mead, AZ/NV. Huge body of water with dry winds. Winter low pressure bring nice winds. Vegas is 30min away!
