Fog is considered to be one of the most characteristic climatic features of the Namib desert. It provides a significant and reliable source of water to desert flora and fauna, may in future contribute towards the water supply of the inhabitants and constitutes a hazard to aviation and shipping. This article describes aspects of both the spatial and the temporal characteristics of fog including annual, seasonal and diurnal fog occurrence patterns, as well as the commencement, cessation times and the intensity characteristics of fog episodes. An attempt is made to explain these characteristics in terms of local and synoptic scale controls. The role of the position and intensity of the South Atlantic Anticyclone and coastal lows are accentuated. Keywords: fog, Namib, spatial patterns, intensity, South Atlantic Anticyclone, coastal low.
