After warm winter, early taste of summer

Today's estimated max temp is 29deg C, 10 deg above the September average.

The BOM records that it's already reached 27 at 10.27 though it's fallen to about 25 at noon.

Climatologist Blair Trewin in The Punch reflects on the warm August many Australians have just experienced:

August 2009 was Australia’s warmest on record. Temperatures averaged over the country were 2.47C above the long-term average, nearly a degree above the previous August record set in 1998, and 25% of the country had its hottest August day on record at some stage during the month.

Trewin points out

Average temperatures in Australia have warmed by about 0.8C over the last 100 years, most of it in the last 50.

and concludes

...while we can’t blame global warming for any individual extreme warm event it is certainly making these events more common.
