Tswalu is a year-round destination. Add to this its vastness and diversity of fauna and flora, and it becomes evident that no two safaris can ever be the same nor yield exactly the same sightings. Throughout the year, wildlife sightings are influenced by seasonal changes to the environment triggered by the presence or absence of water. The more rain, the denser the vegetation cover and longer the grass, which makes sightings of the smaller and more elusive species more challenging. During summer, dramatic cloud formations and thunderstorms are typical, sometimes threatening downpours without delivering a drop of rain or producing isolated, localised showers to parts of the reserve. A season of average, or above average, rainfall greens the landscape with tall grasses and flowering annuals. Winter is the dry season, characterised by cold early mornings and evenings, brilliant blue skies, and golden grasses drying out and dying back. At any time of the year, keen photographers will appreciate the colours, contrasts and brilliant light clarity of the Kalahari.
