Minnesota has a continental-type climate and is subject to frequent outbreaks of continental polar air throughout the year, with occasional Arctic outbreaks during the cold season. Occasional periods of prolonged heat occur during summer, particularly in the southern portion of Minnesota, when warm air pushes northward from the Gulf of Mexico and the southwestern United States. Pacific Ocean air masses that move across the Western United States produce comparatively mild and dry weather at all seasons.

Mean annual temperatures range from 36 degrees Fahrenheit ( F) in the extreme north to 49 degrees along the Mississippi River in the southeast. State temperature extremes range from -60 to 114 F.

Monthly mean temperatures vary from 85 in the southwest to -11 F in the northwest. Mean temperatures during January in the northern portions of the State average near 4 F; this is 10 degrees colder than temperatures recorded at stations near Lake Superior and in southern Minnesota.

The mean temperature in July for the State averages about 70 F in most places but this is five to 10 degrees warmer than at stations near Lake Superior. Thus, Lake Superior stations are cool in summer and relatively warm in winter.
