The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.

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 at Léopold Sédar Senghor International Airport is very rapidly increasing during April, rising from 34% to 58% over the course of the month.

For reference, on August 14, 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 7% of the time.
