Annual Climate Report 2011

Download the Annual Climate Summary report

The Annual Climate Summary 2011 report is the Bureau of Meteorology's official summary of the Australian climate in 2011. It contains descriptions of Australia's rainfall and temperature patterns during the year, and documents significant weather and climate events.

2011, like 2010, was a La Niña year with well-above-average rainfall. Flooding was a persistent feature of the year, affecting large areas of the north and east of Australia. Back-to-back La Niña events led to a highest-on-record two-year rainfall total, and for 2011 alone, it was the second-wettest year on record. 2011 was the first time in a decade that Australia recorded a cooler-than-average annual mean temperature, although below-average temperatures were mostly confined to northern Australia. Globally, 2011 was the equal-tenth-warmest year on record.
