The biggest waves ever recorded on the Great Lakes rolled right past the U.P. — nearly three stories tall. Press play.
Everyone outside the Midwest hears the word “lake” and pictures calm, flat water. Then they see what Lake Superior waves look like in a full-blown November storm.
Press play.
That’s not the ocean. That’s the same water Yoopers swim in every summer, whipped up by what people up here call the Witch of November — the brutal fall storms that tear across the biggest freshwater lake on the planet.
How big do Lake Superior waves get?
Big enough to pass for the ocean. The biggest ever recorded anywhere on the Great Lakes — nearly 29 feet — were measured right off the U.P., between Marquette and Munising, back in October 2017. That’s about the height of a three-story building, rolling across fresh water. For comparison, the seas the night the Edmund Fitzgerald went down in 1975 were in the 25-foot range.
When the wind lines up just right, Superior will throw water clean over lighthouses and toss 700-foot freighters around like bath toys. Same lake, same temper that battered the keepers out at the loneliest lighthouse in America for decades.
These days the storms even pull a crowd nobody saw coming — big-wave surfers, paddling out into near-freezing water off Marquette to ride swell most people swear can’t exist in Michigan.
Yoopers have always known the thing everyone else forgets the second they hear the word “lake.” Superior isn’t really a lake at all. It’s an ocean that just happens to be fresh.
