South Africa is located in the southern hemisphere, so the seasons are opposite to those in the northern hemisphere. The country has two main climatic zones, and the weather can vary greatly depending on the region. The north of the country, including Johannesburg, the Kruger National Park, Limpopo Province, the Kalahari Desert, Durban, and northern KwaZulu Natal, has a more tropical climate, while the south of the country, including Cape Town, the Cape Winelands, Cederberg Mountains, Hermanus, the Karoo Desert, Garden Route, Port Elizabeth, and the Eastern Cape, has a more temperate climate.

According to the search results, the seasons in South Africa are as follows:

• Spring: September, October, and November
• Summer: December to February
• Autumn: March, April, and May
• Winter: June to August

It is worth noting that the weather can vary greatly depending on the region, and the best time to visit South Africa depends on your interests and priorities. For example, the best safari season is technically during the dry season from May to October, when game viewing conditions are really good. The best time to visit Cape Town and the south of the country is from November to March, when you can expect warm, dry weather. Nonetheless, unless you are a specialist, very experienced, a bird watcher, or visiting Cape Town and its surrounding environs, May through to the end of September are the best times to travel in South Africa, with the peak season being June, July, and August.
