When to visit SA                 
South Africa is an all year destination.
Best time for game viewing is late winter to early spring: July to October. During the dry season, the animals can’t hide in high grass and they gather around the waterholes. Animals can be seen all year round, in spring with their offspring. Whales can be seen off the coasts from mid June to the end of October Diving is generally best from April to September. River Rafting is better at the end of winter in the Cape, in summer (late November to February) in KwaZulu-Natal. Hiking: spring and autumn (since summer can be very hot)
