"Australia has recorded its driest September since records began in 1900 with a
national rainfall average of just 4.83mm.
The data from the Bureau of Meteorology on Monday came as fires burned out of
control in Victoria and New South Wales amid warnings of potential flash
flooding later in the week.
Total rainfall was 70.8% below the 1961-1990 average for September, influenced
by a positive Indian Ocean dipole, the recently declared El Niño and the
long-term effects of the climate crisis.
The BoM said September – also one of the driest months overall since records
began – was dominated by high-pressure systems that brought settled weather
conditions and cloudless sky for most of the country.
It was also Australia’s third-warmest September on record, with a national mean
temperature 2.43C above average.
In some states, the heat pushed higher still. Western Australia recorded its
warmest September on record and NSW and Victoria their second warmest. Those
three states also recorded their hottest September days on record.
“The high-pressure systems were the main influence for our warm and dry weather
across Australia throughout September,” the BoM climatology specialist Nadine
D’Argent said.
The mean maximum temperature nationally was 3.38C above average, the
second-highest on record for the month of September."
