Sara and John say...
From arid desert in the north to summer greenery in the south; from intense heat inland to refreshing breezes on the coast - Mauritania has variety in its warm climate.
Northern parts of the country are dry nearly all-year-round. Sea mist sometimes occurs, but while coastal areas are bathed by a cooling sea breeze, keeping highs in the 20s Celsius, temperatures soon soar inland by day. They can reach well over 40 Celsius by day - dangerously high for unprepared visitors. However nights are chilly.
Further south, the heat is accompanied by humidity, particularly during the summer months. Monsoon rains break out, particularly from July to October - causing the desert to undergo a green transformation. Direr conditions return by winter, together with lower humidities.
Sunscreen is a ‘must’, whatever the time of year.
