September weather forecast
Mauritania

September in Mauritania brings a welcome change in weather as the harsh summer begins to wane and the country transitions into autumn. However, temperatures during this month remain high, reflecting the country's desert-dominated climate.

In the capital city, Nouakchott, average temperatures in September range from 23°C (73.4°F) to 35°C (95°F). The city's coastal position on the Atlantic Ocean helps to temper the extreme heat. The city of Atar, located in the country's desert interior, experiences a broader range in temperatures, with lows around 25°C (77°F) and highs reaching up to 41°C (105.8°F).

September also marks the tapering of the rainy season in the southern Sahelian zone. While rainfall declines compared to the peak months of the season, it can still reach around 60mm (2.36"). The northern desert regions of Mauritania remain largely dry in September, maintaining the stark climatic contrast within the country.

Compared to August, September sees a slight decrease in temperatures, signifying the onset of the cooler autumn months. As the country progresses into October, these temperatures will continue to decline, making for more pleasant travel conditions. However, visitors during September should still be prepared for hot conditions and potential rainfall in the south.
