December typically sees the start of the summer rains in the north with isolated heavy showers and thunderstorms. Coastal towns are cooler and often foggy in the mornings. Travel to remote regions may be impacted by sudden downpours.

coastline to Sossusvlei
December typically feels hot in the desert by midday and humid if thunderstorms develop; the coast stays temperate with strong onshore wind and frequent morning fog around Luderitz and Swakopmund. Summer thunderstorms further inland can be spectacular but can cut off minor gravel roads temporarily, so keep flexible plans. Despite heat, late evenings are comfortable for campfires whenever park regulations allow.
Windhoek, Waterberg, Brandberg
December returns to a pattern of warm, humid days with regularly timed afternoon thunderstorms; lightning is common and can curtail long hikes. Festive-season travel around Windhoek increases, so book transfers early; pools and lodges near the plateau are lively. Lightweight rain gear, mosquito protection and flexible driving windows are essential for this active, wet month.
Etosha, Kunene, Omusati
December brings the full onset of the wet season in the far north: hot, humid afternoons with regular thunderstorms, swollen rivers and a spike in insects. Game viewing moves from permanent pans to broader floodplain behavior and night-time drives may be limited by storm activity. Lightweight breathable clothing, strong insect repellent and adherence to lodge guidance on wet-season access are essential.
Katima Mulilo, Rundu, Divundu
December is hot, sticky and prone to heavy thunderstorms that build each afternoon; river channels swell and local flooding is possible in low-lying areas near Katima Mulilo. Lodges that focus on river activities may change schedules for safety, but the dramatic skies and breeding birdlife create unique photographic opportunities. Bring strong insect repellent, quick-dry clothing and accept that plans can shift with the weather.
Fish River Canyon, Keetmanshoop, Karas
December is hot and increasingly prone to short, violent storms; afternoon lightning and sudden downpours can occur, temporarily swelling small rivers and making canyon floor approaches risky. Tourist facilities are busier around holiday season, and lodges near Fish River Canyon fill quickly-book early. Bring shade, hydration gear and heed local advice about river and trail safety during stormy spells.
There are no major festivals or events in Namibia during December to be aware of.
