Recent droughts during the early 1980s have led to the belief that rainfall over Southern Africa has changed or follows some form of periodic behavior. Annual rainfall at 20 stations in Zimbabwe covering the period 1891 to 1988 is analyzed for the presence of trends, discontinuities, persistence and periodicities. The results show that droughts cannot be described by any of these processes.
