The dry season in Africa varies depending on your location- however, in Mwiba the rains come in around November. The change is not as dramatic as in some places, like Liuwa Plain National Park, where the entire plain is flooded under a couple of feet of water and you use boats instead of cars BUT there is still a change. I am very excited to watch the dry, dead looking vegetation turn into a canvas of neon green with splashes of pink and yellow and purple wildflowers. From the first rain in October or November to the height of the wildflowers in March takes about 5 months, but it is well worth the wait.
