What is the weather like in South Africa in December?

December is full summer in South Africa, bringing hot, sunny weather across much of the country. Long days and clear skies make it one of the best times to visit South Africa, ideal for coastal getaways, safari drives, and exploring mountain trails. From Cape Town’s beaches to Kruger’s game reserves, the conditions are set for outdoor adventures.

However, sporadic thunderstorm rains may occur during this time in some regions, especially on the coast and in the Eastern Cape. These rains are usually brief and can be a refreshing respite from the heat, but they may require flexible travel plans, especially for outdoor adventures.

Transportation in December is generally reliable, although you should be prepared for busier roads and potentially crowded public transportation, as this month falls during high season for both international tourists and local vacationers.

Average rainfall in December varies considerably from region to region. The Western Cape Province receives minimal rainfall during the dry season, making it a great time to visit Cape Town and its surroundings.

In contrast, the northeastern parts of South Africa, including Johannesburg and Kruger National Park, experience a wet season characterized by high humidity and frequent afternoon showers.

Average daily temperatures in December

December is summer in South Africa, with average high temperatures ranging from 77°F to 86°F (25°C to 30°C) and average low temperatures ranging from 59°F to 68°F (15°C to 20°C), indicating that it is generally hot throughout the country at this time.

Northern regions

In the northern regions, temperatures are warmer but slightly milder compared to coastal areas. Maximum temperatures can reach 82°F (28°C) during the day and drop to 59°F (15°C) at night. Highveld's altitude makes the cool evenings favorable for outdoor activities and wildlife watching.

Interior Plateau

South Africa's inland plateaus, including the Free State and Gauteng, have similar temperatures to the north, but maximum temperatures can be slightly higher due to the lower altitude. 

Daytime temperatures stay around 84°F (29°C) and nights drop to 61°F (16°C), providing a comfortable climate for exploring the cultural and historical attractions of the central parts of the country.

Coastal areas

On the south coast, temperatures are slightly lower due to the moderating influence of the ocean. The average temperature is around 77°F (25°C) and the minimum is 59°F (15°C). This region enjoys warm weather without the northern heat, which is ideal for visiting beaches, hiking, and vineyard tours.

Is December a good time to visit South Africa?

The weather in South Africa in December is classic summer: hot, sunny, and made for being outdoors. It’s one of the liveliest months of the year, with long days and a festive atmosphere setting the tone across the country. From Cape Town to the Yard Route, December brings energy, color, and crowds.

If you're after sun and sea, this is the perfect time to visit some of the best beaches in South Africa. The Atlantic coast is cooler and scenic, while the Indian Ocean side, especially around Durban, offers warm waters and a laid-back vibe.

Wildlife lovers can still enjoy a wildlife safari in South Africa, particularly in private reserves or less-visited parks. Some regions, like Kruger, see summer rains, but the bush is lush and full of life.

With careful planning, December is a brilliant month for South Africa trips. Consider tailor-made travel options to dodge the crowds and make the most of the summer season.

Why December is a good time to visit:

• City life is buzzing: Big cities like Johannesburg and Cape Town come alive in December. Outdoor events, rooftop bars, and live music fill the calendar before locals head off on vacation.
• Time for the Winelands: Vineyards around Stellenbosch and Franschhoek are in their prime, think long tastings, mountain views, and late sunsets with a glass of something cold.
• Perfect road trip conditions: With dry weather in the south and long daylight hours, December is a great time to hit the open road.
• Hiking season is here: Trails in the Cederberg, Tsitsikamma, and the Drakensberg are lush, accessible, and best tackled in the early mornings before the heat kicks in.
• Early birds win: Travel in the first half of December and you’ll avoid the local vacation surge, with fewer lines, better availability, and a little more breathing room at top spots.

What about crowds and costs?

December is one of the busiest months to visit South Africa. It lines up with school vacations and the festive season, meaning popular destinations and major safari parks fill up fast. Flights and accommodation are in high demand, and prices rise accordingly. If you’re set on traveling in December, it’s worth reservation well in advance to get the best options.

The trade-off? A vibrant summer atmosphere, packed events, and ideal weather for beaches, hikes, and open-air dining. There’s a real buzz this time of year, and many visitors find the energy and celebrations well worth the extra cost.

If you’d rather avoid the crowds and peak-season prices, consider planning your trip to South Africa for the shoulder months, March to May or September to November. You’ll still get great weather, but with fewer tourists and better value across the board.

Where to go in South Africa in December

It’s summer vacation season, and some of the best places to visit in South Africa are at their most vibrant. While it’s a busy time of year, the warm weather, long days, and festive mood make it worth the planning. Here’s where to go.

Cape Town and the Western Cape

December in Cape Town is all about clear skies and outdoor living. Mornings are perfect for hiking Lion’s Head or taking the cable car up Table Mountain, while afternoons call for beach time in Clifton or Camps Bay.

Venture inland to the Winelands for long, lazy lunches in Stellenbosch or Franschhoek. For something quieter, head north to the Cederberg, with less traffic, more stars, and striking red rock landscapes.

The Yard Route

This coastal stretch is popular for a reason. With green forests, calm lagoons, and cliffside drives, it's made for a road-tripping South Africa itinerary. Towns like Knysna and Plettenberg Bay fill up quickly, but early mornings are still peaceful. Go hiking in Tsitsikamma, kayaking in Wilderness, or just slow down and enjoy the scenery.

Eastern Cape reserves

If you’re after wildlife without the crowds, the Eastern Cape delivers. Private game reserves like Amakhala and Kwandwe offer excellent sightings and a more personal feel.

The landscape is lush after early summer rains, and the presence of newborn animals adds something special to each drive. Plus, it's a malaria-free zone, making it a good option for traveling in South Africa with kids.

What to do in South Africa in December

If you’re looking for memorable things to do in South Africa, December offers no shortage of options. With warm weather, festive energy, and long daylight hours, this is the month for getting outdoors, joining the celebrations, and making the most of the country’s wild and urban contrasts.

Hike at sunrise, party at sunset in Cape Town

Cape Town in December is buzzing. Start your day early with a hike up Lion’s Head or a stroll through Kirstenbosch Botanical Yards before the heat kicks in.

By late afternoon, the beaches are packed and the sundowners are flowing. Camps Bay, Sea Point, and even lesser-known spots like Llandudno are perfect for golden-hour lounging.

Safari with a twist in the green season

It’s the rainy season in many parks, but that doesn’t mean skip the safari. The bush is lush, the air is dramatic, and it’s birthing season, so you’ll see young animals and active predators.

Head to a private reserve in the Eastern Cape or Waterberg region for a more relaxed, family-friendly experience without the crowds.

Celebrate summer in the Winelands

December is harvest time in some areas, and the Winelands are alive with picnics, open-air concerts, and long wine tastings. Franschhoek and Stellenbosch are popular, but smaller estates in Paarl or Tulbagh offer a slower, more local feel.
