The lakes ultimately receive their water supply from precipitation, which increases from west to east and from north to south. The average annual precipitation in the Lake Superior basin is 30 inches (760 millimetres), in Lakes Huron and Michigan it is 31 inches, and in Lakes Erie and Ontario it is 34 and 36 inches, respectively. Between 65 and 85 percent of the annual precipitation is lost by evaporation, with the largest proportion occurring on Lake Erie (Erie receives most of its water from Lake Huron). Some water enters Lake Superior from the Hudson Bay drainage system via the Long Lake–Ogoki River diversion, while water drains out of Lake Michigan through the Chicago Sanitary and Ship Canal and the Chicago River diversion.

The lakes greatly modify the climate of the surrounding region. They absorb a large quantity of heat in the warmer months, which is then lost to the atmosphere during the colder months. This causes cooler summers and warmer winters than would otherwise occur in the region. Wintertime precipitation is substantially higher along the eastern shores of the lakes, creating a snowbelt that afflicts Erie, Pa., Buffalo, N.Y., Traverse City, Mich., and similarly situated cities. Severe storms can occur over the lakes, particularly in late fall and early winter. Winds can reach gale force and generate waves 10 feet or more in height. Large areas of the surface waters freeze during winter, although open patches usually remain in the centres of the lakes.
