Waterberg District (South Africa)
& Limpopo River Basin (South Africa, Botswana, Mozambique, Zimbabwe)
The Limpopo basin is mainly located within Koeppen climate zone BSh, representing a semiarid, dry, hot climate. The map below shows that some south and central basin areas lie within a C-type climate. The average annual rainfall is 450 mm but varies considerably across the basin. Between 1979-2013, rainfall reached 160mm/yr in the west of the basin and 1,152mm/yr in the east and southeast areas at the coast (Knight, 2022).

Waterberg district is characterized by hot and semi-arid climate patterns in the North and North-West. The southern and eastern areas of the Waterberg District are more humid and slightly cooler (Department of Environmental Affairs, n.d.). These areas are the green areas in Figure 2 and indicate a CWb climate zone. The mean annual rainfall is around 577 mm, with high yearly mean evaporation of 2100 mm. The minimum average temperature per day is 11.9 ◦C, and the maximum daily average temperatures are around 27.2 ◦C (Netshipale et al., 2022).
