Tsau //Khaeb (formerly Sperrgebiet NP) has a warm and dry climate. It is mostly sunny and there is minimal rainfall.
The altitude in the park varies widely, from below sea level to 1,282m (-62 to 4,206ft). Temperatures drop by about 6.5°C for every increase of 1,000m (or 3.5°F per 1,000ft), resulting in wide-ranging contrasts in climate within the park. Most tourism is at lower altitude and those areas get hotter than the averages shown in the chart above.
