Brisbane, Sydney, Melbourne, Canberra and Adelaide are all likely to set new records for September heat.
The monthly averages of five out of eight capital cities are likely to set new records. Sydney and Adelaide will smash the previous record by around a whole degree.
The country enjoyed its warmest winter on record, but now the heat is building quicker than ever recorded. Clear skies over the nation's interior are heating up the airmass, filtering to most of the state's capitals.
Sydney has set record after record so far this year, and is finishing off its hottest September in over 150 years of records. It could be said that Sydney is two months ahead of itself, as the average maximum of over 24 degrees would sit nicely as November's average.
Adelaide has blitzed its September record by more than a degree, with minima and maxima three degrees above the long term average. The city only experienced four mornings and eight days below the average of 10 to 19 degrees. It will finish the month with a hot and cloudy day on Monday reaching 31 degrees.
Melbourne has had a topsy turvy month, with temperatures ranging from 4 to 25 degrees. It will finish the month with temperatures dipping on Saturday and rising up by Monday.
Canberra joined the plentiful of locations that are setting new heat records this month, but it also set a new record for its wettest September day on Tuesday 17th with 58mm.
Brisbane is finishing the month by surging towards the hottest September record with many very warm and humid days near 30 degrees. It is likely to just exceed the record set in 1980.
The other state capitals were all above average in September, but they failed to set a new September record like the other capitals did.
October is looking hot across the nation, as the clear skies allow heat to continue to build across central Australia. If you don't like the heat then maybe head to Hobart - the only capital city likely to be below average next month.
The cities most likely to set new October records are Brisbane and Sydney, as westerly winds will continue to bring heat into the nation's east.
