Johannesburg is sometimes run down by non-residents, but seriously it has such great temperate weather and those Highveld sunny winter days are the greatest! Also as an Ex-Capetonian, these winter days are without wind! This from me, that has to go through February in KZN...
Oh, I feel for you in KZN, and also for those denialists who swear that the weather in Cape Town in phenomenal (granted, it is great a few days of the year - usually "yesterday" and "tomorrow"). Joburg weather is outstanding, probably among the best in the world, pronounces this Canadian who can testify to what awful weather feels like. :-)
