The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight saving time are indicated by the 'DST' labels.

Humidity

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.

Shreveport experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 5.5 months, from April 28 to October 11, during which time the comfort level is muggy, oppressive, or miserable at least 24% of the time. The muggiest day of the year is July 23, with muggy conditions 95% of the time.

The least muggy day of the year is January 16, when muggy conditions are essentially unheard of.

Wind

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 Shreveport experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 7.3 months, from October 15 to May 24, with average wind speeds of more than 2.6 miles per hour. The windiest day of the year is April 1, with an average hourly wind speed of 3.2 miles per hour.

The calmer time of year lasts for 4.7 months, from May 24 to October 15. The calmest day of the year is July 30, with an average hourly wind speed of 2.1 miles per hour.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences significant seasonal variation over the course of the year.

The brighter period of the year lasts for 4.6 months, from April 9 to August 29, with an average daily incident shortwave energy per square meter above 5.9 kWh. The brightest day of the year is June 16, with an average of 6.7 kWh.

Data Sources

This report illustrates the typical weather in Shreveport, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Shreveport.

For each station, the records are corrected for the elevation difference between that station and Shreveport 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 Shreveport is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Shreveport and a given station.

The stations contributing to this reconstruction are: Shreveport Downtown Airport (83%, 2.0 kilometers, north); Louisiana State Police Troop G Headquarters Facilities Heliport (10%, 8 kilometers, east); and Shreveport Regional Airport (6%, 11 kilometers, southwest).

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.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
