Weather patterns can vary dramatically from the average. Prairie regions, for instance, are
defined by their high variability. On an annual basis, prairies record the hottest summer and the
coolest winter temperatures. Boreal forests have a moderating effect on weather patterns.
Average or mean temperature and rainfall are shown, but expect variability around these
averages.
Temperature averages (degrees Fahrenheit) – Mean maximum / minimum monthly
temperature for each month at several cities in Northern Minnesota. The cities are
presented from northeast to southwest.
