I just got back to the UK from a 2 week holiday in SA. We went North of Pretoria where it was 38 degrees, but didn't feel too bad since it was a welcome break to the miserable cold in the UK and it was reasonably dry heat. I'm from SA originally, you get by with aircon in the office and in the car. Try having to wear a suit when the car's aircon is broken, it sucks.
