The climate of the Nama Karoo tends to be volatile, unpredictable and rather harsh, with only the most specially-adapted organisms calling the region home. The annual ‘dry’ season—a time of blistering hot weather and drought—is long, often taking place over autumn and winter, and into early spring. Heavy rainfall primarily occurs in the spring and summer ‘wet’ season. This time of plenty can also vary, with total measured rainfall fluctuating between 100 and 520 millimetres (3.94 and 20.47 in) per year. Rainfall is also known to be highly seasonal, peaking between December and March. Precipitation tends to decrease from the east to west, and from north to south. As the climate changes, inter-annual rainfall trends become varied, and unpredictability comes to be expected, especially with increasingly prolonged periods of aridity.[2] Temperature variations as large as 25 °C or 45 °F between day and night are common. Mean maximum temperatures in the mid-summer (January) exceeds 30 °C (86 °F), while mean minimum mid-winter (July) temperatures are below freezing.[3]
