August 2009 was the warmest August on Australian record, and the past winter has been the warmest on record for NSW, Victoria and South Australia.
The Bureau of Meterology’s National Climate Centre reported yesterday that the mean August temperature for Australia shattered all previous records, with temperatures 2.47°C above the long-term average, just short of 1°C above the previous record set in 2006.
August mean day-time temperatures were 3.2°C above the average and 1.14°C above the 2006 record.
The recent heat wave set records in 87 long-term monitoring stations, including 37.8°C at Mungindi, NSW, on the 24th and 38.5°C at Bedourie, Qld, on the 29th.
Abnormally warm conditions in June and July combined with August’s record breaking heat to give an Australian-wide mean winter temperature of 16.6°C, some 1.35°C above average.
This fell just 0.01°C short of the previous continental record set in 1996, but NSW, South Australia and Victoria all had their warmest winters on record.
The outlook through to November is for continued warmer-than-normal temperatures, particularly in Queensland and northern NSW.
