It is important to note that the accuracy of free weather data products has not yet been established for many regions, and should therefore be used with care. 

Have you heard about Climate Engine?

Climate ia a tool that enables viewing various sources of climate and weather data either as map layers or time series figures. 

Near real-time measured South African weather data is primarily available from the South African Weather Service (SAWS) and the Agricultural Resource Council (ARC), with each maintaining a set of automatic weather stations across the country.  These data need to be paid for, although special conditions exist, for example, if you are busy with postgraduate studies. 

The South African Atlas of Climatology and Agrohydrology (SAAACA) provides freely available daily weather data at the quaternary catchment scale for the period extending from 1950 up to 1999 (Schulze, 2007). These data are available on the WRO data portal.
