Method and sources
Each point is the average daytime high temperature in degrees Celsius, as printed on the article's temperature and rainfall chart.

The article credits South African Weather Service long-term normals for 1991 to 2020, so the period is that normals window, 1 January 1991 to 31 December 2020.
Our article on Platteklip Gorge prints a slightly different series from the same source, so treat these as rounded normals rather than exact station values.
