According to the Bureau of Meteorology's Seasonal Climate Summary for South Australia, Summer 2010-11 was the third wettest on record.

The well above average rainfall was predominantly a result of one of the strongest La Nina events on record. Forty seven locations, mainly in the east of the state, experienced their wettest summer on record and sixty seven locations had their highest ever daily rainfall in the summer period.

The highest total rainfall for the state was recorded in Ernabella (Pukatja), located in South Australia's pastoral district, with 341.8mm.
