To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Minneapolis experiences extreme seasonal variation in monthly rainfall.
The rainy period of the year lasts for 9.1 months, from March 3 to December 5, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around June 19, with an average total accumulation of 4.3 inches.
The rainless period of the year lasts for 2.9 months, from December 5 to March 3. The least rain falls around January 25, with an average total accumulation of 0.1 inches.
Average Monthly Rainfall
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.
As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Minneapolis experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 5.5 months, from October 28 to April 14, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around December 10, with an average total liquid-equivalent accumulation of 0.5 inches.
The snowless period of the year lasts for 6.5 months, from April 14 to October 28. The least snow falls around July 22, with an average total liquid-equivalent accumulation of 0.0 inches.

Sunrise & Sunset with Twilight and Daylight Saving Time
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
Minneapolis experiences significant seasonal variation in the perceived humidity.
The muggier period of the year lasts for 3.2 months, from June 8 to September 15, during which time the comfort level is muggy, oppressive, or miserable at least 8% of the time. The muggiest day of the year is July 21, with muggy conditions 31% of the time.
The least muggy day of the year is February 26, when muggy conditions are essentially unheard of.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Minneapolis experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 8.0 months, from September 26 to May 26, with average wind speeds of more than 5.0 miles per hour. The windiest day of the year is March 23, with an average hourly wind speed of 6.1 miles per hour.
The calmer time of year lasts for 4.0 months, from May 26 to September 26. The calmest day of the year is August 2, with an average hourly wind speed of 3.9 miles per hour.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.
The brighter period of the year lasts for 3.5 months, from May 5 to August 20, with an average daily incident shortwave energy per square meter above 5.9 kWh. The brightest day of the year is July 10, with an average of 7.0 kWh.

This report illustrates the typical weather in Minneapolis, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Minneapolis.
For each station, the records are corrected for the elevation difference between that station and Minneapolis according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Minneapolis is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Minneapolis and a given station.
The stations contributing to this reconstruction are: Minneapolis-St Paul International/Wold-Chamberlain Airport (41%, 11 kilometers, south); Crystal Airport (39%, 11 kilometers, northwest); and St. Paul Downtown Airport (20%, 17 kilometers, east).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
