Average temperature across Southern Africa in December.
Namibia, southern Angola
Late-summer conditions in November increasingly favour hot, humid inland days and calmer, foggy mornings on the coast; storms become more frequent toward the north. Swakopmund and coastal settlements maintain their cool climate while the interior grows lush after rains - birdlife spikes. Pack rain-proof layers for sudden showers, strong sun protection, and mosquito repellent if you venture into the Zambezi/Caprivi fringes.
Botswana, eastern Namibia, parts of South Africa
December is hot and humid again with frequent afternoon storms that revive the plains and create excellent birding and calf-birthing activity for herbivores. Floodwaters may still be moving through the Okavango depending on the year, producing dramatic waterways and lush channels. Travellers should plan for possible logistical delays after heavy rain and bring lightweight long sleeves for mosquito protection.
South Africa: Cape Town, Stellenbosch, Hermanus, Knysna
December is peak holiday season: hot, dry days and lively beaches around Clifton and Camps Bay with busy roads and full hotels. Festive markets and outdoor dining create a vibrant city scene, but the south-easter can still turn a tide of cool wind - plan outings in calmer morning windows. Reserve key activities in advance and carry sun protection and a light jacket for breezy sites.
South Africa interior: Johannesburg, Pretoria, Bloemfontein, Lesotho
December is warm to hot with regular summer storms and high humidity across the interior; it’s a popular month for South African travelers on holiday. The mountains are green and full of life, but afternoon storms can curtail long hikes; pack lightweight waterproofs and anti-mosquito measures for lower valleys. Expect busy roads and book lodging early for popular mountain and safari gateways.
Durban, St Lucia, Maputo, Eswatini
December is at the height of the warm, humid season - long, hot days with regular tropical downpours and a real chance of cyclonic activity off the Mozambican coast. Coastal resorts are busy and road conditions in low-lying areas can deteriorate after heavy rain. Ensure travel insurance covers storm disruptions, bring sun protection and decent mosquito precautions for evenings near water.
