Average Temperatures in South Africa in August: Your Winter Travel Guide

August in South Africa marks the final weeks of winter, offering a unique travel experience with reliably dry, sunny days and a refreshing crispness in the air. This is a time of transition, as the country begins to shake off the chill of winter and hints at the vibrant spring to come. The clear, bright days cast a beautiful light on the dramatic mountain ranges and ancient landscapes, making it a refreshing season of sensory pleasures.

With South Africa’s temperate climate and the fact that August is during the winter season, you can expect cool weather in the evenings with hotter temperatures arriving in the early afternoon. August falls within the dry season in South Africa, which means rainfall is almost non-existent and you’ll have long days packed with sunshine and warmth.

Due to the weather in August being a rather wide range, we recommend bringing plenty of layers if you are planning to visit South Africa in August. You might want to have an extra sweater or a light coat for the early mornings and later evenings, but in the daytime it might be necessary to take it off.

Here's a detailed look at what you can expect in terms of weather and the best places to visit in South Africa during August.

Overview of South Africa in August

August in South Africa is mostly cool to warm, depending on the time of the day. The country is also mostly dry, with very little rainfall. The days in August see approximately 6-9 hours of sunshine per day depending on the city, and humidity levels are low (with the exception of Cape Town, which is much more humid).

With August being outside of the main tourist peak season (this is November through to March), you will likely find that prices for accommodation, tours, and travel to South Africa are lower. August 9 sees National Women's Day being celebrated throughout the country annually. It is a public holiday, to pay tribute to the women who fought for rights in a system that traditionally did not value women.

Towards Cape Town, the weather is much cooler with more rainfall than the warm, desert climate areas in the northwest. You can expect temperature lows of 6°C in places, which is very cold and wintery. However, most of South Africa is very warm in August with highs of 18°C and up to 12 hours of glorious sunshine per day. The sea water is mild and enjoyable for a swim with gentle breezes often blowing into the coastal regions.

Average Temperatures in Key Cities

To give you a clearer picture, here’s a comparison of the average August weather in three major cities:

  • Cape Town: Average temperatures hover between 64°F (18°C) High and 46°F (8°C) Low, creating cool, comfortable conditions for exploration. Evenings and early mornings are distinctly cold.

Kruger National Park

Kruger National Park is home to a huge number of the most incredible animals, and anyone visiting South Africa in August should seriously consider heading over to this national park. Animals you can see in Kruger National Park include the big five: lions, leopards, elephants, rhinos, and buffalos. This is the best time for a classic safari experience.

Hermanus and Plettenberg Bay

August is the best month of the year to watch whales in Hermanus and Plettenberg Bay, which are not too far from Cape Town. There you'll see the whales after they've migrated from Antarctica, as they prepare to have calves around South African shores.

Discover the whale-watching capital of the world during the peak of the season, when southern right whales arrive to calve and nurse their young.

What to Expect: Feel the thrill as you spot the enormous silhouette of a whale just meters from the shoreline cliffs. Hear the powerful sound of a whale’s tail slapping the water, an explosive noise that echoes across the bay. See mothers and their newborn calves interacting in the calm, protected waters, a truly moving spectacle of nature.

Cape Town

Explore one of the world’s most beautiful cities, where dramatic natural landscapes and a rich history can be enjoyed without the summer crowds.

What to Expect: Feel the brisk wind on your face as you stand atop Table Mountain, gazing at panoramic views of the city and ocean. See the vibrant, candy-colored houses of the Bo-Kaap neighborhood gleaming under the clear winter sun. Hear the stories of South Africa's past during a poignant and powerful tour of Robben Island.

Drakensberg Mountains

The area around the Drakensberg Mountains has many historic battlefields that are a must-see for any military history buff. You'll be able to visit the battlefields of the Voortrekker/Zulu conflict of 1838, as well as that of the Anglo-Boer War of 1899-1902. For the more active traveler, Drakensberg is also home to plenty of hiking trails that are worth visiting for the views and natural landscapes, such as Sani Pass or Maloti-Drakensberg Park.

Namaqualand

Find a surreal escape in this arid landscape when it undergoes a miraculous and ephemeral transformation into a carpet of wildflowers.

What to Expect: See an endless vista of orange, yellow, and purple daisies that blanket the hills and plains as far as the eye can see. Walk along a designated trail in the Namaqua National Park, feeling as if you are the only person in a vast, painted landscape. Breathe in the fresh, clean scent of the blooming desert, a unique fragrance that signals the arrival of spring.

Kalahari Desert

The Kalahari Desert, which spreads from Botswana and Namibia into South Africa's north is an interesting sight to see. It is not a typical dry desert, meaning there are also flora and fauna to see, making it worth spending a day or two on a desert safari or partaking in one of the many activities around the desert.

Essential Packing Tips for August in South Africa

During the dry winter months of April through early September, the days are warm, but the nights can become very cold! Many travelers assume that because they are traveling to Africa, it must always be warm. This is not the case during South Africa’s winter, however, particularly in May through September. You can expect days to be absolutely beautiful, temperate and sunny, but nights and early mornings will be chilly, possibly near freezing, so we recommend you bring warm layers you can peel off as it warms up through the day.

A lightweight down jacket or fleece pullover is ideal. Gloves, hat, scarf and warm long pants are also essential at this time of year for early-morning wildlife drives.
