Indiana Dunes in June: what the park service says
June is summer at Indiana Dunes, which the park calls an ideal time for its 15 miles of Lake Michigan beaches for sand castles and sunsets, the park says. Watch for rip currents: do not swim when warnings are posted or big crashing waves are present, and if one catches you, swim parallel to the shore until you are out of it, then head in. Never swim alone.
