The Best Places to Visit in South Africa in September

Given that South Africa's weather in September is largely warm and dry, this makes it the perfect time of the year to visit many of the different parks, regions, and sights throughout the country.

In particular we would recommend visiting Kruger National Park, heading over to Hermanus for the Hermanus Annual Whale Festival, going hiking in Drakensberg, and spending more time in Johannesburg at the museums and art galleries.

1. Venture on a Morning Game Drive at Kruger National Park

Mornings are when animals in the parks are most active, and Kruger National Park is no different. September is a great time of year to go on a safari and visit Kruger National Park and see the big five: lions, leopards, elephants, rhinos, and buffalos.

There is plenty else to see in the park too, from animals to greenery to magnificent natural landscapes, making Kruger an absolute must-see in South Africa.

If you prefer to do this by foot, you can also arrange for a guided walk or to follow one of the backpacking trails with a guide. There are even areas for mountain biking if two wheels is more your style.

2. Spend Time Exploring Johannesburg and Learn about South Africa

Johannesburg is an incredible city, and the biggest city in South Africa. There are a lot of sights to visit there that will help you understand South Africa's past, including Nelson Mandela's House, the Apartheid Museum, and the South African National Museum of Military History.

For families, there is the Johannesburg Zoo, as well as the Sci-Bono Discovery Centre, and for lovers of art there is the Johannesburg Art Gallery or the Wits Art Museum. There is truly something for everybody.

Nearby you will also find the Cradle of Humankind, a UNESCO World Heritage Site that is home to 15 major sites across limestone caves full of fossils that are dated at millions of years old.

3. Visit Hermanus for the Annual Whale Festival

Hermanus is the whale watching capital of the country, and where, in September, the Hermanus Annual Whale Festival is held in honor of these incredible animals that grace South Africa's coast with their presence. In September you will still be able to see them after their migration from Antarctica, because they come to South Africa to breed. The best time is between July and November, meaning plenty should be around in September.

Go out on a whale-watching boat trip to see southern right whales, who the festival is in honor of, but also humpback whales and Bryde's whales if you are lucky enough. In some places, you will also be able to see the whales from the coast, which is a spectacular occurrence in itself.

4. Hike around the Drakensberg Mountains

The Drakensberg Mountains are home to some beautiful scenery, making for the perfect backdrop for an active holiday destination. September is not too hot for hiking yet, and the dry weather means it is a great time of the year to head on some hikes. The weather there gets significantly wetter in October, so September is a good time of year to go.

You can choose a day-long trail, to head out for a few hours, or even to spend multiple days in the region. Between the Sani Pass, the Amphitheatre Hike, the Maloti-Drakensberg Park, and the Rainbow Gorge, you won't run out of paths.

For an easy hike we recommend the Injisuthi Battle Cave Walk, which takes approximately 5 hours and is not difficult. We can arrange for a guide to take you to ensure you also get informative access to the cave along the way.

Low Season: Less Crowding and Lower Costs

September falls outside of the tourist high season (this is between November and March). As a result, you get to enjoy the beautiful weather as well as less crowding and lower prices for accommodation and travel than later on in the year.

Between September, 28 29, and 30 in 2024, Hermanus sees its annual whale-watching festival to celebrate the return of the southern right whales to South Africa. If you travel to Hermanus during these dates, you'll see a street parade, markets, food, as well as educational marine displays.

September 24 is also when, every year, South Africa celebrates Heritage Day. This is a day to celebrate the cultural wealth of South Africa, and to remember the rich cultures that make up its population. In 2024, September 24 is a public holiday as a result.

What to Wear in September

September's weather lends itself to wearing cotton trousers or jeans, with a t-shirt, and an additional layer like a light jacket or a sweater to wear during the early mornings or in the evenings. This is especially the case if you're heading out to hike in Drakensberg, or if you're looking to go on an early morning game drive in one of the parks.

We also recommend bringing hiking gear if you are planning on going hiking, with proper hiking shoes and backpacks, as well as sunscreen, a hat, and sunglasses to protect yourself against the sun.
