Why is the Lake Erie so rough?
Depth and wind. Lake Erie is the shallowest Great Lake, with a greatest depth of 210 feet and an average depth of 62 feet, and the island region at the west end is the most shallow part. The Coast Pilot says that shallowness and the lake's orientation make it susceptible to southwest and northeast winds, which can quickly raise dangerous seas. Rough seas are most frequent in autumn and in the east half of the lake.
When is the Lake Erie roughest?
The Coast Pilot says strong winds are most likely in autumn during the navigation season, and that November and December are the worst, with gales 6 to 9 percent of the time. Gales are encountered less than 1 percent of the time from May through September. Thunderstorms are generally a problem from April through September and cause some of the strongest winds on the lake.
