In the ACT, Canberra received an impressive 152.6 mm, making this the capital city's wettest November since 191.2mm was recorded at Duntroon Military College in 1924. This was the wettest November on record for Canberra Airport.
In SA, Port Augusta picked up 104.6 mm, making this its second wettest November in 162 years of records, seconded by 141.8 mm in 1882. November 2021 will go down in history for the amount of rain that fell over parts of central and eastern Australia.
While there are a number of factors behind this month's prolific rain, La Niña was a key player in producing the heavy and frequent rain in recent weeks.
