Climate

Experience the Natural Beauty of All Four Seasons.

The Milwaukee Region offers four distinct seasons – summer, fall, winter and spring – each with its own unique beauty and recreational opportunities. Lake Michigan moderates temperatures along the lakeshore, making it slightly cooler in the summer and warmer in the winter.

There are typically only seven days per year when the temperature is 90 degrees or higher. 313 days per year are above freezing (32 degrees), with an average winter temperature of 31 degrees. The average daily temperature is 78 degrees in the summer, which is perfect for sailing on the lake, playing golf or attending one of the area’s many outdoor festivals. July is the sunniest month, with 66 percent of the days bathed in sunshine.

Spring paints the landscape emerald green; fall is a kaleidoscope of colors as trees make way for winter. The average daily temperature in spring is 55 degrees; in the fall, it is 60 degrees. Winter brings about 47 inches of snow, just enough to turn the region into a winter wonderland and offer opportunities for skiing and snowmobiling.


According to the National Weather Service, temperatures range from an average high of:

  • 55 degrees (Fahrenheit) in the spring
  • 79 degrees in the summer
  • 60 degrees in the fall
  • 31 degrees in the winter.
