A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Saskatoon varies throughout the year.
The wetter season lasts 4.0 months, from May 5 to September 6, with a greater than 18% chance of a given day being a wet day. The chance of a wet day peaks at 30% on June 21.
The drier season lasts 8.0 months, from September 6 to May 5. The smallest chance of a wet day is 5% on March 2.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation in Saskatoon changes throughout the year.
Rain alone is the most common for 7.4 months, from March 29 to November 8. The highest chance of a day with rain alone is 30% on June 21.
Snow alone is the most common for 4.6 months, from November 8 to March 29. The highest chance of a day with snow alone is 9% on January 9.
Daily Chance of Precipitation
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. Saskatoon experiences significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 6.2 months, from April 10 to October 16, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around June 22, with an average total accumulation of 2.3 inches.
The rainless period of the year lasts for 5.8 months, from October 16 to April 10. The least rain falls around January 2, with an average total accumulation of 0.0 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. Saskatoon experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 6.6 months, from October 6 to April 23, 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 15, with an average total liquid-equivalent accumulation of 0.3 inches.
The snowless period of the year lasts for 5.5 months, from April 23 to October 6. The least snow falls around July 21, with an average total liquid-equivalent accumulation of 0.0 inches.
Average Liquid-Equivalent Monthly Snowfall
The length of the day in Saskatoon varies extremely over the course of the year. In 2017, the shortest day is December 21, with 7 hours, 43 minutes of daylight; the longest day is June 21, with 16 hours, 46 minutes of daylight.
Hours of Daylight and Twilight
The earliest sunrise is at 4:45 AM on June 17, and the latest sunrise is 4 hours, 30 minutes later at 9:15 AM on December 30. The earliest sunset is at 4:54 PM on December 12, and the latest sunset is 4 hours, 37 minutes later at 9:31 PM on June 24.
Daylight saving time (DST) is not observed in Saskatoon during 2017.
Sunrise & Sunset with Twilight
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 perceived humidity level in Saskatoon, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, staying within 1% of 1% throughout.
Humidity Comfort Levels
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 experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 8.5 months, from September 23 to June 7, with average wind speeds of more than 5.5 miles per hour. The windiest day of the year is April 1, with an average hourly wind speed of 6.2 miles per hour.
The calmer time of year lasts for 3.5 months, from June 7 to September 23. The calmest day of the year is August 3, with an average hourly wind speed of 4.8 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Saskatoon varies throughout the year.
The wind is most often from the north for 1.0 weeks, from March 25 to April 1 and for 4.1 weeks, from April 17 to May 16, with a peak percentage of 29% on April 29. The wind is most often from the east for 3.1 weeks, from May 16 to June 7, with a peak percentage of 29% on May 27.

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 3.7 months, from April 28 to August 19, with an average daily incident shortwave energy per square meter above 5.6 kWh. The brightest day of the year is July 4, with an average of 6.8 kWh.
The darker period of the year lasts for 3.6 months, from October 26 to February 14, with an average daily incident shortwave energy per square meter below 2.0 kWh. The darkest day of the year is December 19, with an average of 0.8 kWh.

This report illustrates the typical weather in Saskatoon, 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 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.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
