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 Donovan Estates is essentially constant during March, remaining around 0% throughout.
For reference, on August 24, the muggiest day of the year, there are muggy conditions 39% 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 Donovan Estates is essentially constant during March, remaining within 0.2 miles per hour of 7.3 miles per hour throughout.
For reference, on April 26, the windiest day of the year, the daily average wind speed is 7.9 miles per hour, while on September 9, the calmest day of the year, the daily average wind speed is 6.2 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).
Temperatures in Donovan Estates are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.
Time Spent in Various Temperature Bands and the Growing Season in March
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 Donovan Estates are rapidly increasing during March, increasing by 523°F, from 653°F to 1,176°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 Donovan Estates.
For each station, the records are corrected for the elevation difference between that station and Donovan Estates 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 Donovan Estates is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Donovan Estates and a given station.
The stations contributing to this reconstruction are: Yuma International Airport (48%, 9 kilometers, southeast); Yuma International Airport (47%, 9 kilometers, southeast); General Rodolfo Sánchez Taboada International Airport (3.3%, 54 kilometers, west); and Blythe Airport (1.3%, 101 kilometers, north).
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.
