Southern hemisphere climate patterns for autumn (March–May) 1993 are reviewed, with particular emphasis on Pacific Basin climate indicators, and on temperature and rainfall over Australia. Marked climate anomalies over other southern hemisphere countries are also briefly summarised. The period saw mature El Niño- Southern Oscillation (ENSO) phase conditions develop for the second autumn in a row, with many of the climatic teleconnections typical of past ENSO episodes in evidence. Over Australia, below average rainfall and above average temperatures in the north and east resembled autumn 1992, and were characteristic of the mature phase of an ENSO event.
