I was forewarned about the fogs that affect the coast of Namibia. The Benguela current sweeps cold water up from Antarctica, and as it passes the African coast it mixes with the warm air coming off the continent. But just because I understand the climatology doesn’t mean that the actual experience of the fog hasn’t come as a surprise because they really are bloody cold; the mornings and evenings here in Swakopmund have not at all been like one might imagine an African beach holiday, more like Morecambe in November. These two swimmers must be seriously hardy.
