HumidityWe 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. Dinguiraye experiences extreme seasonal variation in the perceived humidity. The muggier period of the year lasts for 7.4 months, from April 7 to November 20, during which time the comfort level is muggy, oppressive, or miserable at least 26% of the time. The muggiest day of the year is August 23, with muggy conditions 100% of the time. The least muggy day of the year is December 26, with muggy conditions 1% of the time. Humidity Comfort Levels
The percentage of time spent at various humidity comfort levels, categorized by dew point: dry < 55°F < comfortable < 60°F < humid < 65°F < muggy < 70°F < oppressive < 75°F < miserable.
WindThis 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 Dinguiraye experiences mild seasonal variation over the course of the year. The windier part of the year lasts for 5.8 months, from December 15 to June 9, with average wind speeds of more than 3.1 miles per hour. The windiest day of the year is April 19, with an average hourly wind speed of 3.7 miles per hour. The calmer time of year lasts for 6.2 months, from June 9 to December 15. The calmest day of the year is October 14, with an average hourly wind speed of 2.5 miles per hour. Average Wind Speed
The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.
The predominant average hourly wind direction in Dinguiraye varies throughout the year. The wind is most often from the west for 3.6 weeks, from March 30 to April 24 and for 2.7 months, from June 24 to September 14, with a peak percentage of 46% on July 31. The wind is most often from the south for 2.0 months, from April 24 to June 24, with a peak percentage of 40% on May 20. The wind is most often from the east for 6.5 months, from September 14 to March 30, with a peak percentage of 57% on January 1. Wind Direction
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).
Solar EnergyThis 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.

The area within 2 miles of Dinguiraye is covered by trees (39%), grassland (34%), cropland (17%), and artificial surfaces (10%), within 10 miles by grassland (43%) and trees (41%), and within 50 miles by trees (60%) and grassland (23%). Data SourcesThis report illustrates the typical weather in Dinguiraye, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointThere is only a single weather station, Kéniéba Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Dinguiraye. At a distance of 183 kilometers from Dinguiraye, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere . The weight assigned to the MERRA-2 value depends on the distance from Dinguiraye to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 39%, making the weight assigned to the weather station 61%. Other DataAll 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.
