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 October in Nanton is essentially constant, remaining about 0.1 inches throughout, and rarely exceeding 0.5 inches or falling below -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 Nanton is essentially constant during October, remaining around 0% throughout.
For reference, on July 5, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 1, 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 Nanton is gradually increasing during October, increasing from 6.1 miles per hour to 7.0 miles per hour over the course of the month.
For reference, on January 17, the windiest day of the year, the daily average wind speed is 8.2 miles per hour, while on August 3, the calmest day of the year, the daily average wind speed is 5.0 miles per hour.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Nanton typically lasts for 4.4 months (134 days), from around May 14 to around September 25, rarely starting before April 26 or after June 1, and rarely ending before September 6 or after October 14.
The month of October in Nanton is more likely than not fully outside of the growing season, with the chance that a given day is in the growing season rapidly decreasing from 34% to 0% over the course of the month.
Time Spent in Various Temperature Bands and the Growing Season in October
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Nanton are gradually increasing during October, increasing by 71°F, from 1,477°F to 1,548°F, over the course of the month.

This report illustrates the typical weather in Nanton year round, 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 6 weather stations near enough to contribute to our estimation of the temperature and dew point in Nanton.
For each station, the records are corrected for the elevation difference between that station and Nanton 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 Nanton is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Nanton and a given station.
The stations contributing to this reconstruction are: Stavely Aafc (26%, 20 kilometers, southwest); Champion AGDM (37%, 31 kilometers, east); Sparwood/Elk Valley Airport (14%, 46 kilometers, west); Strathmore AGDM (8%, 83 kilometers, northeast); Cop Upper (8%, 86 kilometers, north); and Calgary International, Alta. (8%, 87 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.
