The Great Lakes do get waves. Mostly, they are fairly calm waves, but it can get turbulent during bad weather. Not the same as the literal meaning of tide I guess. Although, maybe so. I do think there are some tidal shifts. I need to google.
The shoreline does change. I remember visiting a friend who has a cottage on Lake Huron and almost her entire “beach” behind her house was gone, because the water had come so close to the house. It was t so much tidal, but like the lake was very full the days I was there.
The sand by her house is filled with beautiful smoothed over lake stones by her house. Stones you can fit in your hand that are smoothed over, fairly flat, and oval-ish shaped mostly by her house.
If you have been to the Gulf beaches on the west coast of Florida its a lot like the Great Lakes on most days. One noticeable difference is the saltiness of the ocean compared to the fresh lake water. People not used to the ocean usually notice the difference when they accidentally swallow some water.
A lot of people have a hard time imagining how large the Great Lakes are. I was staying in Elkhart Lake, WI and told a couple of friends with me (from Memphis) that I wanted to go to Lake Michigan, and asked if they wanted to come. Elkhart Lake itself has a nice moderately sized lake, but it’s a typical interior lake in a small town.
Lake Michigan was about 30 minutes away. As we neared the lake we crossed over a small waterway, maybe 25 ft wide, and one of them asked if that’s the lake. This is an American who is a smart women. 5 minutes later we were at Lake Michigan, at a beach, and it was blue like the Caribbean, and large like the ocean, unable to see any land on the other side. She had no concept that it would be that way.
I remember the first time I went to the Great Lakes, it made quite an impression on me. I too hadn’t really understood the vastness, even though I was familiar with the geography. I was a teenager at the time.
