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 in the year. Munising experiences significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 9.9 months, from March 4 to January 2, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around September 28, with an average total accumulation of 3.3 inches.
The rainless period of the year lasts for 2.1 months, from January 2 to March 4. The least rain falls around February 1, with and average total accumulation of 0.3 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 in the year. Munising experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 5.9 months, from November 3 to April 30, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around January 6, with an average total liquid-equivalent accumulation of 0.9 inches.
The snowless period of the year lasts for 6.1 months, from April 30 to November 3. The least snow falls around July 31, with an average total liquid-equivalent accumulation of 0.0 inches.
Average Liquid-Equivalent Monthly Snowfall
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.
Munising experiences some seasonal variation in the perceived humidity.
The muggier period of the year lasts for 2.9 months, from June 22 to September 19, during which time the comfort level is muggy, oppressive, or miserable at least 4% of the time. The muggiest day of the year is August 1, with muggy conditions 15% of the time.
The least muggy day of the year is November 28, 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.

This report illustrates the typical weather in Munising, 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 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Munising.
For each station, the records are corrected for the elevation difference between that station and Munising 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 Munising is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Munising and a given station.
The stations contributing to this reconstruction are: Munising, Munising Lakeshore Observation (94%, 0.6 kilometers, north), Sawyer International Airport (2.3%, 58 kilometers, west), Schoolcraft County Airport (2.3%, 60 kilometers, southeast), and Delta County Airport (1.4%, 83 kilometers, southwest).
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.
