The Perth metropolitan area has recorded its wettest September for 40 years.
It has rained in Perth for 20 of the past 30 days.
So far this month the city has recorded 144 millimetres of rain while the average is 81.
That makes it the wettest September since 1973.
The level of water in Perth dams remains low despite the record amount of rain.
The Water Corporation's Ben Jarvis says the dams are 38 per cent full.
He says 16 billions litres of rainwater has flowed into the dams in the past week.
Mr Jarvis says that is more than dams received during the entire winter of 2010.
