Wisconsin experiences a continental climate with four distinct seasons, characterized by cold winters and warm summers. The state’s weather varies significantly throughout the year, influenced by its location in the Upper Midwest and proximity to the Great Lakes.
Winters in Wisconsin are typically cold and snowy, with average temperatures often below freezing from December through February, especially in northern areas like Green Bay and Superior. Snowfall is common, making winter activities popular. Spring brings a gradual warm-up with increasing rainfall, while summers are generally warm and humid, with temperatures ranging from the mid-70s to mid-80s Fahrenheit, sometimes reaching the 90s in southern cities like Milwaukee and Madison. Fall features cooler temperatures and vibrant foliage. Wisconsin also experiences occasional severe weather, including thunderstorms and tornadoes, primarily in late spring and summer. As of 2026, the climate remains consistent with these seasonal patterns.
