When is the best weather to visit Minneapolis?

Normal highs sit between 65°F and 85°F in May, June, July, August and September. Of those, September has the fewest days with rain (9).

That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

Has Minneapolis been warmer than normal lately?

2025 averaged 48.3°F, 1.4°F above the 1991-2020 normal of 46.9°F. 4 of the 5 complete years since 2021 ran warmer than the normal.

How does Minneapolis's climate compare?

Minneapolis is warmer than 125 of the other 128 places with their own NOAA record in Minnesota, and wetter than 77. Across the 7,247 U.S. stations with normals, its annual mean of 46.9°F is warmer than 27%.

In the Köppen classification computed from these normals, Minneapolis is Dfa: continental, no dry season, hot summer. What the classes mean.

Which places near Minneapolis share this climate record?

6 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
