An areal average data series based on 18 stations scattered throughout south and east England was set up. The incomplete gamma function was used as a model for the frequency distribution of the data, since it gave good agreement with the parameters of the longest record in the area, Kew (1697–1971). The power spectrum of the areal average series shows that non‐linear processes on a time scale of months or years may be involved in rainfall fluctuations. Decade average values of the total monthly rainfall of the area series were used to forecast decade mean monthly rainfall totals for 1970–1979, 1980–1989 and 1990–1999, using a mixed time series model.
