Spring in Minnesota can be short and tends to come late, which can have visitors and residents alike itching for the warmer weather of summer. So when does summer finally arrive in this northern Plains state known for its long, cold, and snowy winters? Here's a look at Minnesota's seasons and when you can finally get a taste of summer.

Leading Up to Summer

March is firmly a winter month in Minnesota. Although winter is easing and snow melts on warmer days, usually more snow falls through this month. The first official day of spring falls in mid-March, but you wouldn't know it in Minnesota. The weather doesn't obey the seasonal labels that are relevant in many other states. You'll have to wait well until springtime until Minnesota actually feels like spring. 

April has many above-freezing days and the potential of warm spring days when it is delightful to be outside. The snow has usually melted by the end of April. Finally, it feels like spring.

But not for long. The beginning of May is usually cool, but the temperature warms throughout May to see real summer weather and heat by mid-May. So much for spring.

What feels like true summer weather usually starts sometime in May in Minnesota, well before the official first day of summer in mid-June. Then summer can hit hard, depending on where you are located in the state. Up north, summer highs tend to hover in the high 70s F, with the mid-80s F predominating in the south. Temps can spike as high as 114 degrees during a heat wave in that region of the state. 

Official Start of Summer in Minnesota

The official start of summer in Minnesota is on the summer solstice, either June 20 or June 21, as it is in the rest of the Northern Hemisphere.

Unofficial Markers of Summer in Minnesota

Regardless of the date on the calendar, you can tell it's summer in Minnesota when you:

  • Get your first mosquito bite
  • Get your first sunburn
  • Take your first swim in a lake
  • See the first small car with a large canoe strapped to the top of it on the road
  • Notice that the giant pile of snow in the downtown St. Paul Sears parking lot has finally melted
  • Hear people who whine about snow switch to whining about the humidity
  • Get stuck in your first road construction traffic snarl, described by the adage "Minnesota has two seasons: winter and road construction"
