Sunrise & Sunset with Twilight in August

The solar day over the course of August. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray.

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.

The chance that a given day will be muggy in Webb is decreasing during August, falling from 97% to 88% over the course of the month.

For reference, on July 25, the muggiest day of the year, there are muggy conditions 97% of the time, while on January 24, the least muggy day of the year, there are muggy conditions 2% of the time.

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 Webb is essentially constant during August, remaining within 0.1 miles per hour of 2.7 miles per hour throughout.

For reference, on March 7, the windiest day of the year, the daily average wind speed is 4.0 miles per hour, while on August 6, the calmest day of the year, the daily average wind speed is 2.6 miles per hour.

The lowest daily average wind speed during August is 2.6 miles per hour on August 8.

Average Wind Speed in August

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.
The wind direction in Webb during August is predominantly out of the west from August 1 to August 16 and the east from August 16 to August 31.

Wind Direction in August

The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions (north, east, south, and west), excluding hours in which the mean wind speed is less than 1 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Water Temperature

Webb is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average surface water temperature in Webb is essentially constant during August, remaining around 84°F throughout.

The highest average surface water temperature during August is 85°F on August 14.

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 in Webb is essentially constant during August, remaining within 0.1 kWh of 5.6 kWh throughout.

Data Sources

This report illustrates the typical weather in Webb year round, 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 Webb.

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

The stations contributing to this reconstruction are: Dothan Regional Airport (64%, 18 kilometers, west); Early County Airport (21%, 39 kilometers, northeast); and Marianna Municipal Airport (15%, 48 kilometers, south).

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.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .
