From December the Kalahari turns green, water stands in the Etosha pans, and the migrant birds arrive. Springbok and oryx calves are on the ground, the dunes at Sossusvlei sit under real cloud instead of a flat blue sky, and the light in the late afternoon is the reason photographers book this window on purpose. Most days are dry and hot. What people call the rain season here is a handful of spectacular afternoon storms that build, break and clear inside two hours — which is worth reading about before you decide.
The other half of it is the roads. Sesriem, Deadvlei and the Etosha waterholes are busy in July and quiet in January, and you will spend the day passing far fewer vehicles on the gravel. Lodge availability opens up and so do the rates. If you are weighing the two windows against each other, our high season versus green season comparison lays out the trade-offs honestly, including the ones that count against green season.
