December weather forecast
Mauritania

December in Mauritania marks the full onset of the winter season. Despite the country's location in the tropics, temperatures continue to decline during this month, offering relief from the intense heat that characterizes much of the year.

In Nouakchott, the coastal capital, average temperatures in December range from 15°C (59°F) to 28°C (82.4°F). The city's proximity to the Atlantic Ocean plays a crucial role in moderating its climate, keeping the temperatures relatively mild. On the other hand, Atar, located in the desert interior, experiences temperatures between 13°C (55.4°F) and 30°C (86°F). The stark temperature drop during the desert nights contributes to this range.

December maintains the trend of aridity seen throughout most of the year in Mauritania. Both the northern desert regions and the southern Sahelian zone receive almost no rainfall during this month, further highlighting the country's overall dry climate.

Compared to November, December experiences a further decrease in temperatures. As the country moves from December into the New Year, these milder temperatures persist, continuing to offer pleasant conditions for travel and exploration. Despite the more comfortable weather, visitors should still prepare for cooler evenings, especially in the desert regions.
