Temperatures begin to rise notably, especially inland. Travel is still manageable though days grow hot; prepare for strong sun and large diurnal temperature swings in the desert.

Average temperature across Mauritania in March.
Nouakchott, Nouadhibou, Banc d’Arguin
By late winter the Atlantic upwelling still holds the coast in mild temperatures and morning fog, though days lengthen and warm slightly. Nouakchott’s bustling markets feel less oppressive than they will in spring, making strolling and city visits pleasant; dunes near the city are crisp and dry. If you plan a wildlife boat trip or to visit the Banc d’Arguin reserve, book ahead for better seats - the calmer seas make for smoother trips.
Atar, Chinguetti
March marks the beginning of the warming trend across the plateau: afternoons get hot and the sand reflects intense sun, so plan activities for early morning and late afternoon. Sand-laden gusts become more common as the season prepares to peak, and the soft light around sandstone arches is excellent for photography. Travelers should carry plenty of water, cover skin from sun and sand, and avoid long daytime treks during the hottest hours.
Tiris Zemmour, Zouérat, F’dérik
March brings a steady warming, with strong sun and increasing wind that can kick up fine sand across open plains; long shadows on mesas make for striking photos. The highest temperatures are still tolerable by desert standards, but wind-driven grit affects comfort - goggles and zipped layers are helpful. For travelers planning to visit iron-ore sites or use regional roads, check with operators about dust conditions and mechanical readiness.
Néma, Bassikounou
March brings warming throughout the Hodh region and an uptick in gusty winds that can raise dust; daytime temperatures climb noticeably while evenings remain temperate. Travelers planning to explore remote wells and pastoral routes should prefer early starts and prepare for dusty conditions that can affect breathing and camera gear. Arranging a local guide remains advisable for off-road routes that look passable but can hide soft sand.
Rosso, Kaédi, Boghé
March brings warming and an increase in humidity as the Sahel prepares for the rains; daytime temperatures rise and late afternoons can feel sticky following brief cloud build-up. Riverine agriculture begins to show early signs of spring growth in irrigated plots, and bird migration activity shifts. Travelers should plan for hotter afternoons, prefer early-morning river trips, and be ready for occasional dust-laden winds.
There are no major festivals or events in Mauritania during March to be aware of.
