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 Kanab is essentially constant during May, remaining around 0% throughout.
For reference, on July 22, 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 Kanab is essentially constant during May, remaining within 0.2 miles per hour of 9.4 miles per hour throughout.
For reference, on April 10, the windiest day of the year, the daily average wind speed is 9.8 miles per hour, while on August 13, the calmest day of the year, the daily average wind speed is 6.7 miles per hour.
Average Wind Speed in May
The hourly average wind direction in Kanab throughout May is predominantly from the west, with a peak proportion of 53% on May 31.

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 Kanab typically lasts for 5.6 months (171 days), from around April 30 to around October 18, rarely starting before April 10 or after May 24, and rarely ending before September 27 or after November 8.
The month of May in Kanab is more likely than not fully within the growing season, with the chance that a given day is in the growing season rapidly increasing from 52% to 94% over the course of the month.
Time Spent in Various Temperature Bands and the Growing Season in May
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 Kanab are increasing during May, increasing by 371°F, from 311°F to 682°F, over the course of the month.

Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Kanab.
For each station, the records are corrected for the elevation difference between that station and Kanab 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 Kanab is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Kanab and a given station.
The stations contributing to this reconstruction are: Colorado City Municipal Airport (52%, 44 kilometers, west); Bryce Canyon Airport (14%, 81 kilometers, northeast); Cedar City Regional Airport (19%, 89 kilometers, northwest); and Page Municipal Airport (16%, 97 kilometers, east).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.
