Climate and Weather in Mauritania
Mauritania occupies the western Sahara, creating climate conditions that differ substantially from what most travel summaries convey about West Africa. The northern two-thirds of the country experiences an extremely hot and dry Saharan climate, while the southern strip along the Senegal River transitions into semi-arid Sahel conditions. Understanding the Mauritania location within this geographic context explains why temperature extremes dominate travel planning more than rainfall patterns.
The coastal strip around Nouakchott maintains somewhat moderated conditions due to Atlantic trade winds, though this effect diminishes rapidly inland. Harmattan winds blow from the Sahara most of the year, except along the narrow coastal zone. These winds carry dust that makes it hard to see and can cause sandstorms in open areas, especially during the months when the seasons change. The Adrar region, home to UNESCO-listed Chinguetti and Ouadane, endures the full intensity of continental desert conditions.
Annual rainfall ranges from under 100 mm in the north to approximately 500 mm in the extreme south. Most precipitation falls between July and September.

Understanding the Seasons in Mauritania
Mauritania follows a dry-season structure dominated by temperature variation rather than the wet-dry cycles characteristic of tropical West Africa. The sections below outline baseline conditions for periods without activity prescriptions.
Cool Season in Mauritania (November to February)
- Daytime temperatures range from 20°C to 30°C in most regions, while nights drop to 10–15°C in desert areas and can approach near-freezing in the Adrar interior.
- Monthly rainfall remains negligible across the country, with clear skies prevailing and humidity levels staying very low throughout this period.
- Harmattan dust can reduce visibility on some days, though overall conditions support extended outdoor activity and desert camping without heat-related constraints.
Transitional Period in Mauritania (March to April)
- Heat builds steadily through this period, with daytime readings climbing from 30°C in March toward 38°C by late April across interior regions.
- Rainfall remains minimal, and conditions stay dry, though wind patterns begin shifting, and dust events become more frequent in exposed areas.
The Mauritania flag flies at government buildings during Independence Day celebrations on November 28th, marking a key cultural moment.
Hot Season in Mauritania (May to September)
- Temperatures exceed 40°C regularly in interior regions, including the Adrar, with Nouakchott coastal readings slightly lower due to maritime influence but still reaching 35–38°C.
- The short rainy period from July through September brings modest precipitation to southern regions—sometimes causing flooding risk in Nouakchott—while the north remains virtually rain-free.
- Sandstorms occur more frequently during May and June when hot desert winds intensify, creating hazardous conditions for overland travel.
Late Transition in Mauritania (October to November)
- Temperatures begin moderating from summer peaks, with readings settling between 28°C and 35°C across most travel corridors by late October.
- Rainfall tapers to negligible levels as the dry season reasserts itself, and humidity decreases noticeably compared to the brief wet period.
- As conditions improve, access to the desert gradually reopens, though some interior locations continue to experience residual heat into early November.
Best Time to Visit Mauritania by Travel Style
Optimal timing shifts based on individual heat tolerance and specific destination priorities within this challenging environment. The sections below address distinct travel categories separately.
Best Time for Sightseeing
December through February delivers the most comfortable conditions for exploring Mauritania's historic sites and urban areas.
Temperatures stay warm enough for daytime activity without reaching the debilitating levels that characterize summer months. Daylight hours average eight to ten hours daily, providing adequate windows for outdoor exploration. Nouakchott's markets and the ancient libraries of Chinguetti remain accessible without heat-related constraints that would otherwise limit walking time.
Best Time for Value-Focused Travel
June through September represents the cheapest time to visit Mauritania due to minimal tourism demand and extreme heat deterrence.
Accommodation rates in Nouakchott decrease when summer conditions discourage most visitors from attempting travel. Flight pricing from European hubs softens during these months. The tradeoff involves temperatures exceeding 40°C that make desert travel inadvisable and occasional flooding that can disrupt Nouakchott transportation—the best season to travel to Mauritania clearly falls outside this window.
Best Time for Festivals
The date harvest from mid-June through August draws communities to oasis towns, though extreme heat limits participation for most visitors.
Travelers researching top things to do in Mauritania may encounter references to this agricultural tradition centered in the Adrar region oases. The Festival du Ténéré in Nouakchott showcases traditional music during cooler months. Cultural events concentrate in the capital of Mauritania, Nouakchott, where the National Theater hosts performances throughout the dry season.
Best Time for Nature and Adventure
October through April aligns with optimal conditions for Banc d'Arguin National Park visits and Saharan desert expeditions.
Banc d'Arguin hosts over two million migratory birds between October and April, when European, Siberian, and Greenland species winter along the Atlantic coast. Desert crossings to Chinguetti and the Richat Structure become feasible once temperatures drop below dangerous levels. Game drives and camel treks operate most reliably during the cooler months when guides can safely conduct multi-day expeditions.
Worst Time to Visit Mauritania
The worst time to visit Mauritania spans May through September, when extreme heat renders desert travel dangerous and limits practical activity to coastal areas with significant restrictions.
Interior temperatures routinely exceed 40°C during this period—conditions that create genuine health risks for travelers attempting overland journeys. The Adrar region, containing Mauritania's primary cultural attractions, becomes essentially inaccessible for standard tourism. 4x4 vehicle operators and desert guides suspend most services during peak heat months. Tour operators schedule their Mauritania departures exclusively between November and March for these operational reasons.
July through September adds flooding risk in Nouakchott when rare but intense rains overwhelm drainage infrastructure. The brief wet season can make unpaved roads impassable and disrupts urban transportation unexpectedly. Combined with persistent heat, these months represent the definitive worst time to visit Mauritania for any travel purpose.

How Weather in Mauritania Can Affect Travel Plans
Weather patterns introduce operational constraints that determine whether specific itineraries remain feasible in this challenging environment. Verifying the time difference in Mauritania matters when coordinating with contacts abroad during schedule disruptions.
- Heat limitations: Summer temperatures exceeding 40°C in the Adrar region create genuine health risks, and most tour operators suspend desert expeditions entirely between May and October regardless of client demand.
- Sandstorm interference: Harmattan winds carrying Saharan dust can reduce visibility to near zero and ground flights at Nouakchott International Airport without advance warning during transitional months.
- Flooding disruption: July through September rains occasionally overwhelm Nouakchott's drainage infrastructure, disrupting urban transportation and potentially stranding vehicles on unpaved roads.
- Access dependencies: Desert routes to Chinguetti and Ouadane require specialized 4x4 vehicles and experienced drivers—services that scale down dramatically outside peak season.
- Connectivity gaps: Mobile coverage decreases substantially outside urban areas, making satellite communication devices advisable for remote desert travel where cellular networks do not reach.
