Rainfall

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. Smith Reynolds Airport experiences some seasonal variation in monthly rainfall.

Rain falls throughout the year at Smith Reynolds Airport. The most rain falls during the 31 days centered around July 25, with an average total accumulation of 3.4 inches.

The least rain falls around January 30, with an average total accumulation of 2.5 inches.

Snowfall

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. Smith Reynolds Airport experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 3.6 months, from November 28 to March 16, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around February 2, with an average total liquid-equivalent accumulation of 0.4 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.

Smith Reynolds Airport experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 4.0 months, from May 26 to September 26, during which time the comfort level is muggy, oppressive, or miserable at least 18% of the time. The muggiest day of the year is July 27, with muggy conditions 73% of the time.

The least muggy day of the year is January 12, when muggy conditions are essentially unheard of.

Temperature and Dew Point

Smith Reynolds 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 Piedmont Triad International Airport; Lexington Municipal Airport; Mount Airy/Surry County Airport; Rockingham County NC Shiloh Airport; Blue Ridge Airport; Rowan County Airport; Asheboro, Asheboro Municipal Airport; and Stanly County Airport.

Other Data

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.
