Geography Wisconsin Climate Division 3 is bordered by Lake Michigan to the southeast and the Upper Peninsula of Michigan to the north. The terrain is predominantly covered by forests and gentle hills. It includes the cities of Peshtigo, Marinette, and Shawano. Overview In the southeastern sections near Lake Michigan, the climate of Northeastern Wisconsin sees some mild lake effects, such as increased cloudiness during the fall and winter and moderation of temperatures year-round. For the most part, however, the division is mostly shielded from stronger lake effects. Moving farther inland, this division experiences a largely continental climate, driven by the movement of high and low pressure systems across the continent. As a result, day-to-day temperature variations are larger in the southern sections farther away from the Great Lakes.
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.
