An analysis is given of Pacific basin tropical climate indicators and the southern hemisphere circulation for the austral summer, December 1991 to February 1992. Summer rainfall and temperature are discussed for the Australian region. The season saw mature phase warm ENSO episode conditions develop in the tropical Pacific. Some aspects of the circulation for the season were similar to those of composite patterns for previous warm episodes. Below average summer rainfall over most of the northern half of Australia was typical of a warm ENSO episode.
