Geography Wisconsin Climate Division 6 is bordered by Lake Michigan to the east, includes the Door Peninsula, and extends west to include the cities of Appleton, Oshkosh, and Fond du Lac. The land cover is a mixture of urban development, forests, and agriculture. The terrain is flat to hilly. Overview The climate of East Central Wisconsin is strongly influenced by Lake Michigan when winds are out of the east. Under these conditions, cooler air from Lake Michigan brings the division mild summer temperatures, while increased precipitation may accompany the warmer fall and early winter temperatures. In the late winter as ice builds up on the lakes, temperature variations are usually similar to those at inland locations. Because the day-to-day weather is controlled by the movement of pressure systems across the continent, this area seldom experiences prolonged periods of extreme weather. The northern areas of the division are prone to long, snowy winters.
In partnership with the Midwest Regional Climate Center and the Office of the Michigan State Climatologist, GLISA has developed summaries of the observed historical climate for NOAA U.S. Climate Divisions within the Great Lakes basin. Each summary includes an overview of temperature and precipitation to help guide local-level climate adaptation decisions.
