When is the best time of year to visit Cape Town, South Africa?

I got to Cape Town quite often. It is perfectly safe as long as you stay out the townships and only venture into the suburbs and main tourist areas at night. Even though January is summer, do not go then because it is incredibly windy. The best times are about September to December and February to April. May is okay but it starts to cool down a bit. If you want to go diving with great white sharks, then it is better to go in the winter months, perhaps in June or July, because visibility in the water is better then. Be warned though that in winter, the sea is freezing and you have to put warm clothes underneath your diving suit. You can have lots of fun in Cape Town, in fact, in the whole of South Africa. Don't forget to spend some time in Johannesburg. Most tourists do not know what to look for there, so they miss out on a lot. Speak with a local and you will find Johannesburg has tons to see, to do and to buy.

NEVER!!! It's a 4 seasons in 1 day place...disgusting. PS. All my fellow SA citizens know by now I hate CT...they only have a huge flat rock and an ice cold sea...the people are great though.
