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 Dakar is very rapidly increasing during April, rising from 30% to 53% over the course of the month.
For reference, on August 15, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 25, the least muggy day of the year, there are muggy conditions 6% 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 Dakar is essentially constant during April, remaining within 0.1 miles per hour of 7.5 miles per hour throughout.
For reference, on April 8, the windiest day of the year, the daily average wind speed is 7.6 miles per hour, while on September 23, the calmest day of the year, the daily average wind speed is 4.5 miles per hour.
The highest daily average wind speed during April is 7.6 miles per hour on April 8.

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 Dakar is essentially constant during April, remaining within 0.1 kWh of 7.1 kWh throughout.
The highest average daily incident shortwave solar energy during April is 7.2 kWh on April 23.

This report illustrates the typical weather in Dakar 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 Dakar.
For each station, the records are corrected for the elevation difference between that station and Dakar 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 Dakar is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Dakar and a given station.
The stations contributing to this reconstruction are: Léopold Sédar Senghor International Airport (98%, 7 kilometers, northwest); Kaolack Airport (1.0%, 162 kilometers, east); and Banjul International Airport (0.9%, 173 kilometers, southeast).
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.
