Whyalla is on track to record its wettest November ever following a Spring season affected by multiple climate drivers including a developing La Nina pattern.
The Bureau of Meteorology (BoM) have recorded 103.6mm of rain in the steel city so far this month, which is on track to eclipse the previous record of 109.7mm set in 1914.
Port Augusta has also had its wettest Spring in 16 years, recording a total of 78.1mm so far, way above the 55.8mm received in 2005 and the average of 21.5mm.
Other sites have been similarly drenched, including Port Lincoln (33.mm, average 19.2mm), Cleve (52mm, average 27.3mm) and Kyancutta (72mm, average 21.7mm).
In a statement, the BoM said a negative Indian Ocean Dipole (IOD), forming La Nina pattern (now declared), and positive Southern Annual Mode had combined to drive rainfall this Spring.
"All of these contribute to the chances of above-average rain in eastern and parts of southern Australia during spring and summer," they said.
