Climate chart - Nouakchott (Mauritania)
The climate of Nouakchott is tropical arid.
The city is the capital of Mauritania and is located on the coast, at the 18th parallel north.
The coolest period is from December to February, when the temperature can drop as low as 10 °C (50 °F) at night.
The prevailing winds come from the north, and are cool when they come from the north-west, and hot and dry when they come from the north-east.
Only in July and August do winds from the west prevail, so the heat is less intense than in the previous and following months, but it is more humid.
Meanwhile, the sea gradually becomes warmer, and the intertropical convergence zone, where clouds and rains form, approaches from the south, reaching Senegal.
In August and September there may be some rare rain due to the African monsoon, which however normally remains further south.
The hottest months are September and October, when the wind becomes more variable, so much so that it sometimes blows from the south.
