Even in summer, the climate in Johannesburg or Cape Town is not too bad — average daily highs of 17 C or so. However, they’d probably hold the Games in the local spring or early summer, as was done in Melbourne (held in November-December) and Sydney (held in September.)
Many a true word is spoken in jest.
I assume you mean winter rather than summer - although tomorrow’s predicted high in Cape Town is just 17C…
The problem with winter in Cape Town is the rain - it can rain steadily for weeks at a time, and when it rains, the wind blows - not conducive to athletic activities. If any city in South Africa were to be awarded it, I would think it would go “up north” - better weather, better infrastructure, better transport links, most of the population, but more crime as well…
Having said that, it was Cape Town that won the right to bid for the 2004 Olympics, so you never know.
