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. Regina experiences significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 6.3 months, from April 12 to October 20, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around June 26, with an average total accumulation of 2.3 inches.
The rainless period of the year lasts for 5.7 months, from October 20 to April 12. The least rain falls around January 11, with and 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. Regina experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 6.2 months, from October 10 to April 15, 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 31, with an average total liquid-equivalent accumulation of 0.3 inches.
The snowless period of the year lasts for 5.8 months, from April 15 to October 10. The least snow falls around July 26, with an average total liquid-equivalent accumulation of 0.0 inches.

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 Regina, 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 2% of 2% throughout.

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 windier part of the year lasts for 8.3 months, from September 25 to June 5, with average wind speeds of more than 5.9 miles per hour. The windiest day of the year is March 31, with an average hourly wind speed of 6.6 miles per hour.
The calmer time of year lasts for 3.7 months, from June 5 to September 25. The calmest day of the year is July 22, with an average hourly wind speed of 5.2 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.

This report illustrates the typical weather in Regina, 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 Regina.
For each station, the records are corrected for the elevation difference between that station and Regina 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 Regina is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Regina and a given station.
The stations contributing to this reconstruction are: Regina (50%, 4.0 kilometers, southwest); Regina University (50%, 4.0 kilometers, southwest); Indian Head (0.7%, 69 kilometers, east); and Last Mountain (0.3%, 116 kilometers, north).
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.
