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 Charlotte is essentially constant during March, remaining around 0% throughout.
For reference, on July 24, the muggiest day of the year, there are muggy conditions 80% of the time, while on January 24, the leasy 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 Charlotte is essentially constant during March, remaining around 3.9 miles per hour throughout.
For reference, on March 8, the windiest day of the year, the daily average wind speed is 3.9 miles per hour, while on August 1, the calmest day of the year, the daily average wind speed is 2.5 miles per hour.
The highest daily average wind speed during March is 3.9 miles per hour on March 8.

Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Charlotte.
For each station, the records are corrected for the elevation difference between that station and Charlotte 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 Charlotte is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Charlotte and a given station.
The stations contributing to this reconstruction are: Charlotte Douglas International Airport (75%, 10 kilometers, west); Charlotte–Monroe Executive Airport (14%, 31 kilometers, southeast); and Concord Regional Airport (11%, 36 kilometers, northeast).
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.
