Australia is also one of the driest continents on earth with an average annual rainfall of less than 600 millimetres. Like all countries in the southern hemisphere, Australia's seasons are opposite to those in the northern hemisphere.
The September 2012 rainfall total at Adelaide (Kent Town) was 21.8mm received on 12 rain days. This is very much below the long term average of 60.3 mm on 13 or more rain days, and results in the driest September in Adelaide since 2008 when only 16.0 mm was observed.
