Monday, 2 September 2013 - Monthly Climate Summary for Queensland - Product code IDCKGC24R0
lowest August rainfall on record (12.7 mm, lowest since 2009).
Most of the state saw no rainfall this month. While this is usual
for the tropical north in August, it is less usual in the southern part
of the state.
The wettest overall was Whyanbeel Valley with 122.0 mm, followed by Mossman South Alchera Drive with 78.8 mm, followed by Daintree Village with 53.0 mm.
The wettest single day was at Whyanbeel Valley with 115.6 mm on the 24th, followed by Mossman South Alchera Drive with 74.0 mm on the 24th, followed by Daintree Village with 42.0 mm on the 24th.
first significant rainfall event of the month came on the 17th and 18th
as a high sat over the Coral Sea and another high was over the Red
Centre and between them a trough pushed across the southern border of
the state bringing over 5 mm of rainfall to the far southeast corner of
On the 22nd and 23rd a strong ridge reached across most of the continent. While most of the country were seeing clear skies and rising temperatures, the stronger onshore flow brought rainfall to the tropical coast.
Across the state, this month, the mean temperature (average of daily
maximum and minimum) was 19.1 °C (6th highest on record) which is 1.3
°C warmer than normal for August and the warmest since 2009. This warm
mean temperature was driven by warm maximum temperatures while minimum
temperatures were near normal for the month (as explained in the
The warmest on average was Coconut Island with 27.3 °C, followed by Horn Island with 26.3 °C, followed by Weipa Aero with 25.5 °C.
The coolest on average was Stanthorpe Leslie Parade with 9.7 °C, followed by Applethorpe with 9.9 °C, followed by Warwick with 11.7 °C.
Persistent high pressure and fewer
clouds than normal allowed for daytime maximums to rise higher than
usual this month. The monthly mean maximum temperature across
Queensland was 27.8 °C, which is 2.6 °C above average (25.1 °C), the
2nd highest on record (record was in August 2009). Maximum temperatures
across the state were above average, to very much above average.
Maximums in the Channel Country and Maranoa and Warrego three to four
degrees above average whereas in the Northern Districts the monthly
mean daily maximum temperatures were only around one degree above
The hottest day was at Birdsville Airport with 37.5 °C on the 31st, followed by Century Mine with 37.1 °C on the 30th, followed by Urandangi Aerodrome with 37.0 °C on the 31st.
The warmest days on average were at Century Mine with 33.1 °C, followed by Kowanyama Airport with 33.0 °C, followed by Weipa Aero with 32.8 °C.
The coolest days on average were at Applethorpe with 17.4 °C, followed by Stanthorpe Leslie Parade with 18.5 °C, followed by Toowoomba Airport with 20.2 °C.
The coldest day was at Applethorpe with 10.9 °C on the 20th, followed by Applethorpe with 11.4 °C on the 8th, followed by Stanthorpe Leslie Parade with 12.0 °C on the 20th.Some sites had their highest August mean daily maximum temperature on record.
In slight contrast to the maximum temperatures, minimum temperatures across Queensland in August were near normal. On average humidity levels were low this month. This would have allowed for hot days, but for most of that heat to radiate away at night allowing overnight minimums to drop. The mean minimum temperature across the state this month was 10.46 °C which is only 0.03 °C below the long-term mean (10.43 °C) ranking 62 of 104 years of record. This near normal state-wide mean minimum temperature may not represent individual regions of the state. For example, the Channel Country saw minimum temperatures that were between one and three degrees above average, while across the Peninsula mean minimum temperatures that were between one and three degrees below normal for August.

A Monthly Climate Summary is prepared to list the main features of the weather in Queensland using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.
This statement has been prepared based on information available at 10 am on Monday 2 September 2013. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Averages are long-term means based on observations from
all available years of record, which vary widely from site to site.
They are not shown for sites with less than 9 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.
The Rank indicates how rainfall this time compares with the climate record for the site,
based on the
(very low rainfall is in decile 1, low in decile 2 or 3,
average in decile 4 to 7, high in decile 8 or 9
and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
The ACORN-SAT dataset is being used for temperature area averages from December 2012 onwards. The major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, rather than 1950, and hence rankings are calculated using a larger set of years.
