Mauritania in September

November through March is your window. Temperatures hover around 25-30°C during the day and drop to comfortable levels at night. The harmattan winds can bring dust storms, but they're manageable. Avoid April through October unless you enjoy 45°C heat and sandstorms that block out the sun. Even locals retreat indoors during these months. Ramadan affects travel significantly. Restaurants close during daylight hours, and desert tours become more challenging. Check Islamic calendar dates before booking. The brief rainy season (July-September) in the south brings some greenery but also makes roads impassable. Stick to the dry season for reliable travel conditions.
