The following research was compiled by: Kate Rowntree, Department of Geography & Catchment research Group, from Rhodes University.
An autographic raingauge was installed at Ganora in 2009; the first readings were recoreded in July of that year. Rainfall enters the bucket which tips once 0.2 mm is recieved. Each tip sends a signal to the recording device which records the total number of tips over a 5 minute interval.
Monthly rainfall figures demonstrate that the 2010-2011 summer season was consistently wet, with the rains starting in September, reaching a peak in January and Febraury, but continuing through June and July. The 2009-2010 and 2011-2012 summer rainy season were both more erratic. The high annual total for 2011 can be seen from the inserted table below.
