South Africa has a very variable rainfall regime across the country - some areas are clearly seasonal (both summer and winter rainfall), some are aseasonal (can expect rain at any time of the year) and in the far north-west of the country there are very arid areas that receive only a small amount of rain each year. These results all indicate that the increases in the annual rainfall observed in the south and some central parts of the country are at least partially the result of increases in individual high or extreme rainfall events.

Significant increases might indicate that the risks of high rainfall of short duration became more prevalent, which in turn indicates a higher probability of related disasters such as flash floods. Therefore, it follows that the particular stations used in the calculation of district rainfall values vary through time, more so for those districts with a relatively denser network of stations. 6, indicate whether there are trends in the annual maximum daily rainfall amounts. In addition to the data discussed above, the delineation of districts of homogeneous rainfall, as used by the South African Weather Service (SAWS), aided in the attempt to cover as much of the areas with unique rainfall characteristics as possible.

For dry climates it will be much fewer than 1 500 and for wetter climates significantly more. Due to the substantial distances and the complex nature of rainfall in South Africa, mainly due to the regionally different rainfall-producing mechanisms or systems and the complex topography in some regions, it is difficult to perform proper quality control on rainfall data.
