Short summary
An investigation of the wet season characteristics including wet day frequencies, wet–dry spells, and season onset, end and length is done for Cape Town, South Africa. The temporal changes since 1841 in these characteristics indicate an increased incidence of shorter wet seasons and long dry spells in the most recent 3 decades compared to previous years. There is evidence of some associations between solar cycles and the Southern Oscillation index cycles with the wet season characteristics.
