It is clear skies for Cape Town.  The area is mostly dry with trees, but has parks with lots of green grass and there are bird sanctuaries.  Lake Sandvlei is surrounded by houses and a bird sanctuary. Another lake is Zeekoevlei.  In the center of Cape Town there is a castle called the Castle of Good Hope and is mostly industrialized.

Global and Local Winds in South Africa

The latitude and longitude of South Africa is 30 degrees S and 25 degrees E in the Southern Hemisphere.  South Africa resides in the mid-latitude cell.  The Westerlies blow for South Africa and the prevailing wind direction is NW.  An anticyclone, which is a High pressure system, travels over the country during April.  The Horse Latitudes are located near South Africa.  The 30 degrees S is the line for the Horse Latitudes and South Africa lines up with it.

Global Wind Patterns (wiki)

Because of the wind patterns of Westerlies and the anticyclone, South Africa tends to be warm and due to the latitude of 30 degrees S, it has a desert and is very hot and dry.  The anticyclone makes the area very sunny with little clouds so it gets hot in the day time.

South Africa has mountains and winds associated with mountains are mountain breezes, katabatic winds, anabatic winds, foehn winds and valley breezes.  I think that South Africa can experience all of those types of winds depending on the weather and season.  There is a coastline and the breezes are land and sea breezes.  South Africa can experience both.
