December Weather in Johannesburg
Is December Right for You?
Advantages
- Summer thunderstorm season creates dramatically clear mornings with that intense African light photographers dream about - UV index hits 8, so you get those crisp shadows and brilliant colors before the afternoon clouds roll in around 3pm
- Jacaranda trees are still finishing their bloom in early December, particularly in the northern suburbs like Rosebank and Parktown, creating those purple-canopied streets you see in every Joburg postcard
- School holidays don't start until mid-December, which means the first two weeks are surprisingly quiet at major attractions like the Apartheid Museum and Constitution Hill - locals are still at work, international tourists haven't arrived yet
- December marks the start of the festive season when Johannesburg's outdoor culture really comes alive - rooftop bars in Braamfontein, Sunday markets in Neighbourgoods, evening concerts at Zoo Lake all operate at full capacity because the weather actually cooperates
Considerations
- Afternoon thunderstorms are genuinely intense and happen roughly 10 days throughout the month - not the gentle tropical drizzle you might expect, but proper lightning-and-thunder affairs that shut down outdoor activities from about 3pm to 6pm when they hit
- From December 15th onward, accommodation prices jump 40-60% as South African families start their summer holidays and international visitors arrive for the festive season - that sweet spot of quiet tourism ends abruptly mid-month
- The 14°C (58°F) morning temperatures catch first-timers off guard because Joburg sits at 1,753 m (5,751 ft) altitude - you'll need layers even though it's technically summer, and outdoor breakfast plans require a jacket until 9am
Best Activities in December
Soweto Township Cultural Tours
December weather is actually ideal for exploring Soweto because morning temperatures around 18°C (64°F) make the walking portions comfortable, and most tours finish by 2pm before the afternoon storms. The township comes alive during December with festive preparations - you'll see street braais being set up, Christmas decorations in unexpected places, and a genuine buzz that's missing during winter months. The clear morning light at this altitude makes Vilakazi Street and the Mandela House incredibly photogenic. Worth noting that local guides tend to be more available in early December before their own holiday plans kick in mid-month.
Cradle of Humankind Cave Explorations
The Sterkfontein Caves and Maropeng Visitor Centre are perfect December activities because they're largely underground or indoor, making them excellent backup plans when afternoon thunderstorms hit. The 18°C (64°F) constant cave temperature actually feels refreshing after the humid morning heat. December is low season here before the January rush, so you'll have more intimate experiences in the caves without being stuck behind large tour groups. The drive out to the Cradle, about 50 km (31 miles) northwest of the city, takes you through the Highveld landscape when it's at its greenest after the November rains.
Maboneng Precinct Art and Food Walking Routes
This revitalized neighborhood in downtown Joburg is brilliant in December because the Sunday Market at Arts on Main runs at full capacity with outdoor seating actually being pleasant in the 22-25°C (72-77°F) morning temperatures. The precinct's mix of galleries, street art, and rooftop bars means you can easily move indoors when afternoon storms threaten. December brings a festive energy with special exhibitions and live music events that don't happen during the quieter winter months. The area is compact enough - about 1.5 km (0.9 miles) end to end - that you can explore on foot without exhausting yourself in the heat.
Lion and Rhino Park Safari Drives
December is actually excellent for this accessible game reserve just 45 km (28 miles) north of Joburg because the summer vegetation is lush and animals congregate around water sources during the warm afternoons, making sightings more predictable. The morning game drives starting at 6:30am take advantage of that cool 14°C (58°F) dawn temperature when animals are most active. Unlike winter when it's genuinely cold in an open vehicle at dawn, December mornings are comfortable with just a light jacket. The afternoon thunderstorms typically hold off until 3pm, giving you a solid window for activities.
Johannesburg Botanical Gardens and Walter Sisulu National Botanical Garden Visits
December is peak flowering season at both gardens, with the summer rains bringing everything into bloom. The Walter Sisulu Garden, about 25 km (15.5 miles) northwest in Roodepoort, has a resident pair of Verreaux's Eagles nesting on the cliffs - December is when you might spot recently fledged chicks. The morning humidity around 70% actually keeps the gardens feeling fresh rather than oppressive, and the afternoon storms usually announce themselves with enough warning to seek shelter in the tea gardens. These spaces are where Joburg locals go to escape the city heat, so you'll see actual weekend culture rather than just tourist activities.
Apartheid Museum and Constitution Hill Historical Tours
These indoor-focused historical sites are strategically perfect for December because you can spend 2-3 hours in climate-controlled spaces during the hottest part of the day or when storms hit. The Apartheid Museum's architecture and layout are designed to be experienced slowly, which suits the weather pattern of lingering indoors. December's significance isn't lost on locals - it's the month when many reflect on the country's journey as the year ends. Constitution Hill's outdoor sections, including the Old Fort and Number Four prison, are actually manageable in December mornings before 11am when temperatures are still comfortable at 20-22°C (68-72°F).
December Events & Festivals
Johannesburg Festive Lights Switch-On
The city's official festive season launch typically happens in early December with the lighting ceremony in Sandton City and along Nelson Mandela Square. It's become a proper event with live music, food vendors, and that particular South African festive energy that mixes Christmas traditions with summer vibes. Worth experiencing if you're around because it shows you how Joburg celebrates - outdoor, social, and with a soundtrack that's decidedly more Afrobeats than carols.
Carols by Candlelight Events
Multiple venues across Joburg host outdoor carol services throughout December, with the most popular at the Johannesburg Botanical Gardens and various church grounds. These are genuinely atmospheric because they happen at dusk around 6pm when temperatures have cooled to 20°C (68°F) and the afternoon storms have usually passed. Bring a picnic blanket and join local families for what's become a December tradition - though expect a uniquely South African mix of traditional carols and contemporary gospel.
