Limpopo can be quite warm in August. First thing in the morning at dawn it will be chilly on the bakkie. A coat might be needed plus hat etc. Cool for the first walk. By mid-morning it will have warmed up and won't be carrying the coat anymore. Evenings by the campfire will be coolish, but nothing a Dane will feel coming South.

Clear nights in Southern winters can get down to frosty conditions of course given enough moisture.
