A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Saskatoon, the chance of a wet day over the course of December is essentially constant, remaining around 7% throughout.
For reference, the year's highest daily chance of a wet day is 30% on June 22, and its lowest chance is 5% on March 3.
Probability of Precipitation in December
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. As with rainfall, we consider the liquid-equivalent snowfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day liquid-equivalent snowfall during December in Saskatoon is essentially constant, remaining about 0.3 inches throughout, and rarely exceeding 0.6 inches or falling to 0.0 inches.

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.
The chance that a given day will be muggy in Saskatoon is essentially constant during December, remaining around 0% throughout.
For reference, on July 20, the muggiest day of the year, there are muggy conditions 3% of the time, while on September 25, the least muggy day of the year, there are muggy conditions 0% of the time.

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 Saskatoon is essentially constant during December, remaining around 5.6 miles per hour throughout.
For reference, on April 1, the windiest day of the year, the daily average wind speed is 6.2 miles per hour, while on August 3, the calmest day of the year, the daily average wind speed is 4.8 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 in Saskatoon is essentially constant during December, remaining within 0.1 kWh of 0.9 kWh throughout.
The lowest average daily incident shortwave solar energy during December is 0.8 kWh on December 19.

Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Saskatoon.
For each station, the records are corrected for the elevation difference between that station and Saskatoon 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 Saskatoon is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Saskatoon and a given station.
The stations contributing to this reconstruction are: Saskatoon John G. Diefenbaker International Airport (97%, 4.4 kilometers, northwest); Watrous East Automated Reporting Station (0.9%, 101 kilometers, southeast); Rosetown East, Sask (0.8%, 106 kilometers, southwest); Elbow Marine Aviation Reporting Station (0.8%, 111 kilometers, south); and Melfort Automatic Weather Reporting System (0.4%, 160 kilometers, northeast).
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.
