Hurricane Florence is impatiently anticipated by surfing community of the US East Coast. It is supposed to hit near Outer Banks, but there is significant air movement inland too. And, it looks like it has something for the Great Lakes surfers. Let's try tracking surfing forecast and conditions on the Great Lakes surf spots with web cameras. "Hurricane hype center" is coined by Ben Gravy, check out his video blog entries in the material below!

• North Side Municipal Beach - popular surf spot with sandbar and reef breaks. Check this video clip from Step Into Liquid: Surf Wisconsin on the summary of local conditions and surf culture.
• The Riptide Double Surf Simulator in Blue Harbor Resort's waterpark. FlowRider machine, see videos: demo of Sheboygan Blue Harbor wave simulator, double wave setup, this guy is rippin' it!. Looks like they allow only their equipment, bodyboards look pretty close to normal ones, surfboard is custom to the machine but seems like workable for a fun session
• Kohler-Andrae State Park . Waves build at offshore reef and beach

Check out Milwaukee, WI too, just 1 hour South.

Woodlawn State Park - shallow beach break gets some surf on strong SW wind. Watch videos of how it looks like in the Summer.

Ashtabula has a bunch of beaches, but most of them are private. Watch this video of Ben Gravy attempting to surf somewhere in the vicinity. Yet, there are at least 3 known surf spots accessible to public:

Walnut Beach Park - sandy beach, may get waves on W, SW and strong NE winds. Watch video for sample conditions in April. Established kiting and windsurfing spot.

Saybrook Park - sandy beach may be blocked now.

Geneva State Park - nice sandy beach.

There is only chance for surfing on W, SW, strong NE winds.

Beaches at Mentor-On-The-Lake start generating surf on NW, W, SW winds.

Headlands Beach State Park

Mentor Beach Park - I honestly don't see where exactly to surf there (maybe there is some other Metro Park in the area), I think the Yacht Club nearby is a better bet.

Overlook Beach Park

Edgewater Park Beach well-established surf spot in Cleveland, OH. Some people call it "the spot" to surf on lake Erie. The lineup can be quite crowded when the the weather is decent and it is warm. The beach itself is popular among general public and can be overflown on nice weather weekends and holidays. Parking can be a challenge. The most convenient is the Lower parking, there is manageable walk from the Upper parking, and pretty far from the West Upper Parking spot.
The best waves build at breakwall and sewer pipe on strong NE, NW, and SW winds. See the webcam for the current conditions. For general info on surfing Cleveland, watch this video. Watch how surfing may look like at Edgewater Park Beach in the Summer, September, October

There are also some references to surfing in Euclid Park - but the sandy beach seem to be spoiled with the wave breakers. West outskirt looks promising though.
