A detailed analysis of the rainfall of Adelaide, South Australia, has shown that throughout the 95 years 1839‐1933 there has been a definite oscillation, with a period and amplitude of approximately 23 years and 30 days respectively in the incidence and duration of the winter rains. The amplitude, though small, is nevertheless about 20 per cent of the length of the rainfall season. The total quantity precipitated has shown no statistically significant changes.
