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 Nouadhibou is very rapidly decreasing during October, falling from 57% to 28% over the course of the month.
For reference, on August 21, the muggiest day of the year, there are muggy conditions 83% of the time, while on January 12, the leasy muggy day of the year, there are muggy conditions 1% 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 Nouadhibou is decreasing during October, decreasing from 7.9 miles per hour to 6.8 miles per hour over the course of the month.
For reference, on June 7, the windiest day of the year, the daily average wind speed is 9.5 miles per hour, while on December 4, the calmest day of the year, the daily average wind speed is 6.4 miles per hour.
The highest daily average wind speed during October is 7.9 miles per hour on October 1.

Temperature and Dew Point
There is only a single weather station, Nouadhibou International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Nouadhibou.
At a distance of 1 kilometer from Nouadhibou, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Nouadhibou according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
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.
