The South shore of lake Michigan has plenty of surf spots along its miles and miles of sandy beaches. They work on winds from the North moving all length of lake Michigan water surface.

Ogden Dunes: West Beach - pounding waves on strong North winds. The beach has a bath house.

Dune Acres: Dune Acres Beach - community (parking can be limited), Porter Beach - parking and bathrooms

Beverly Shores, works best on NW winds: Indiana Dunes State Park - 3 miles of sand and shore breaks, Kemil Avenue Beach, Central Beach

Michigan City: Washington Park Beach

Holland State Park - beautiful half mile sand beach. The surf kicks in on NW.

Tunnel Park - sandbar and shore break work reliably on N, NE, SW winds.

Presquile State Park - shore and sand breaks at Sunset Point and Beach #6 work on NW, W, SW winds. A little bit skeptical on Beach #6 because of wave breakers, but still, that is closest surf spot to Pittsburgh. Check this video by Ben Gravy for a good surf day in the past.

Freeport Beach - waves build along sand and pebble beach on NW, SW.

Considered one of the best surfing spots in Canada Kincardine beach . Waves often rise on NW, SW winds. You may also check Inverhuron Provincial Park beach North of Kincardine. Sandy beach should work well when winds are blowing from SW.

Yet another good place on lake Erie Canadian shore. Check out the Pier at Port Stanley Beach: waves may come at sand bar on SW, SE winds. I'd also have a look at the small sandy beach at Main St. exit, the satellite photo shows some wrinkles coming to the shore.
