Not only is this lake massive - spanning 307 miles in either direction - but its shores also run parallel, causing unique wave shapes. The shapes of these waves are what contribute to rip tides, which are one of the most dangerous things swimmers can encounter in the water.
A north-northeast wind has pushed the warmer surface water along the Michigan shore back toward the middle of Lake Michigan and brought up colder water from well beneath the surface. This process is called upwelling.

The lake's formation began 1.2 billion years ago when two tectonic plates moving in opposite directions left a giant scar—an event now known as the Midcontinent Rift.

Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume and the third-largest by surface area, after Lake Superior and Lake Huron.
Lake Surface TemperatureSurface temperatures of Lake Michigan follow a monthly pattern with the warmest temperatures occurring in late summer and early fall and the coolest temperatures occurring in late winter and early spring (Figure 17).
Erie is the most southerly, shallow, and biologically diverse of all of the Great Lakes. Its shallow depth makes it the warmest Great Lake and a favourite destination for summer recreationists and migrating birds.
Though not as warm as the oceans, temperatures of Lake Michigan do rise to the high 60s in July and August to make swimming enjoyable, and definitely refreshing! Rarely do temperatures make it to the 70s, unless air temperatures stay up in the 90's for many continuous days.
According to the article, the most dangerous creature in Michigan lakes is the Sea Lamprey. I has a round, sucker-like mouth and really harsh, sharp teeth put together in circular rows.
Lake Erie is the fourth-largest lake in North America (by surface area) and the eleventh-largest worldwide. It is the Great Lakes' southernmost, shallowest, and smallest by volume. By the 1960s, Lake Erie had become the most polluted of the Great Lakes, owing to the substantial industrial presence along its coasts.
Lake Michigan wrecks: the oldest and the mostestLake Michigan contains more shipwrecks than any of the other Great Lakes, as well as the oldest recorded one: the French ship Griffon, the first European vessel to sail the Lakes.
