Weather

Namibia has a dry climate typical of a semi-desert country where droughts are a regular occurrence. Days are mostly warm to very hot, while nights are generally coll. Average day temperatures in the summer vary from 20’C -34’C and aver night temperatures in the winter form from 0’C – 10’C.

Temperatures in the interior are lower than in the pre-Namib, because of the altitude, while the cold Benguela Current has a modifying influence on the coastal desert and its hinterland. The Benguela is the prime determinant of the Namib’s climate, as it reduces rainfall an causes the omnipresent fog typical of the coast. An interesting aspect of Namibia’s climate is the vast differences between the arid southern desert and semi-desert areas and the tropical water-rich north east wit its abundant summer rains.

Nevertheless, Namibia is the most arid country in Southern Africa, with a humidity of less than 10% during the winter months and varying from 50% to 80% in the summer. Except for the south-western areas where winter rainfall occurs, rain usually falls in the summer months between October and May, with a short rainy season in November. The main rainy season is from January to March. Rainfall is usually caused by convection thunderstorms. These are unevenly distributed throughout the country and are normally of short duration.

Average rainfall figures vary from less than 50 mm along the coast to 350 mm in the the central and 700 mm in the far north-eastern regions. however, because of the high variability of rainfall, especially in the arid regions, the ‘annual average’ does not necessarily give a true picture. an average rainfall of 200 mm per year, for example, indicates showers of anything between 80 mm and 280 mm.
