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 at Memorial Field Airport is essentially constant during July, remaining within 2% of 84% throughout.
The highest chance of a muggy day during July is 86% on July 22.
For reference, on July 22, the muggiest day of the year, there are muggy conditions 86% of the time, while on January 28, 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 at Memorial Field Airport is essentially constant during July, remaining within 0.1 miles per hour of 3.5 miles per hour throughout.
For reference, on April 1, the windiest day of the year, the daily average wind speed is 5.2 miles per hour, while on July 31, the calmest day of the year, the daily average wind speed is 3.3 miles per hour.
The lowest daily average wind speed during July is 3.3 miles per hour on July 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 at Memorial Field Airport typically lasts for 7.8 months (239 days), from around March 20 to around November 14, rarely starting before March 1 or after April 12, and rarely ending before October 24 or after December 3.
The month of July at Memorial Field Airport is reliably fully within the growing season.
Time Spent in Various Temperature Bands and the Growing Season in July
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 at Memorial Field Airport are very rapidly increasing during July, increasing by 904°F, from 2,227°F to 3,130°F, over the course of the month.

Temperature and Dew Point
Memorial Field Airport has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required.
In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations.
The stations on which we may fall back include but are not limited to Arkadelphia, Dexter B Florence Memorial Field Airport; Mount Ida; Harrell Field; Adams Field; Russellville Municipal Airport; Goodwin Field; Robert Chris McIntosh Airport; and Grider Field.
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.
