Mild days and cooler nights are typical-one of the preferred times for visiting Mauritania's deserts and cultural sites. Clear skies and lower dust levels improve visibility.

Average temperature across Mauritania in December.
Nouakchott, Nouadhibou, Banc d’Arguin
By December the coast settles into its mild, wind-cooled winter rhythm: comfortable days in the low to mid 20s°C, cool, damp mornings, and breezy evenings. Nouakchott is lively with shops and cafés full of locals escaping the interior, and Banc d’Arguin again attracts wintering birds - good for day trips. Bring a warm layer for evenings on the beach and expect boat trips to be pleasant when sea conditions are calm.
Atar, Chinguetti
December returns to cooler desert conditions with brisk mornings and pleasantly warm afternoons; early starts to climb dunes or visit rock engravings are rewarding. The dry season is in full effect so tracks are firm and predictable, and local guides are in demand for multi-day saharan treks. Travelers should pack both sun protection for daytime and warm layers for chilly nights in camps.
Tiris Zemmour, Zouérat, F’dérik
December returns to cooler days and cold nights with stable skies across the mining belt - an agreeable time for motorists and visitors who can tolerate brisk evenings. Dust is generally low, making it easier to see geological features and industrial sites. Services in Zouérat and surrounding towns operate normally, but remote tracks remain isolated; travel with local guidance and a full vehicle kit.
Néma, Bassikounou
December re-establishes the dry season rhythm across eastern Hodh with clear skies, comfortable daytime temperatures and crisp nights - ideal for long drives and cultural tourism. Roads are at their most dependable and services in towns like Néma run smoothly, which helps when planning transfers to remote areas. Travelers should plan early morning starts to make the most of cooler, dust-free hours and carry warm layers for night.
Rosso, Kaédi, Boghé
December is one of the most agreeable months to visit the Senegal River valley: sunny days, cool nights and stable roads make movement easy and outdoor activities enjoyable. Riverfront towns are active and dry-season farming practices are visible in the fields, while birds congregate on remaining wetlands. Travelers should still bring sun protection for bright days and expect lively local markets and comfortable travel conditions.
There are no major festivals or events in Mauritania during December to be aware of.
