South Africa weather overview

A pleasant climate is a major asset in South Africa's drive to distance itself from past controversy and place itself firmly on the world tourism map. If travelling to South Africa, remember that, because it lies south of the equator, its seasons are the opposite to those of North America and Europe.

Only the low-lying areas in the north, along the borders with Zimbabwe and Mozambique, have a tropical climate with related high temperatures and humidity. In the south, the coastal lowlands around Cape Town have a Mediterranean climate with hot summers (September to May) and warm, rainy winters.

The eastern coastlands and the low veld of Durban and Natal have a subtropical climate with most rainfall falling between October and April, which is also the period of highest temperatures and humidity. The western coastal strip has a cold sea current which keeps temperatures cool and generates plenty of low cloud and fog but almost no rain.

In the eastern interior or high veld (where Johannesburg and Pretoria are situated), summers are rainy and warm and winter days are mild although temperatures can drop dramatically at night. The low humidity and high number of sunshine hours produce a pleasant and healthy climate all year. The western interior is mostly desert or semi-desert and has a hot, sunny climate. What rain there is falls between November and April.

What to pack for South Africa weather

Take light clothing and be prepared for rain if visiting between September and May. Pack warmer wear if travelling during their winter.
