Wisconsin Climate Divisions

Wisconsin has nine climate divisions. A climate division has been defined by the National Climatic Data Center to be an area of the state that has relatively uniform climate characteristics.

These regions, which were created in 1950, correspond to the Crop Reporting Districts of the U.S. Department of Agriculture and typically have boundaries corresponding to county and state boundaries, except in mountainous states where topographic features are used to determine the boundaries.

Each Wisconsin climate division comprises several counties.
