An archive of previous monthly summaries for Queensland is also available, as are summaries for other states and many other climate summaries and diagnostics.

Details

Early in September the weather was moderated by the passage of weather systems that provided a few reasonable rainfall totals. Trade winds brought isolated showers to the east coast and a thundery rain band moved across southern and south-eastern Queensland between the 3rd and 5th and produced moderate falls in the south-east. Showers and thunderstorms triggered a few daily falls over 50 mm in the Hervey Bay/Wide Bay area to 9am on the 8th.  

From mid month conditions became more emphatic as a north to north-westerly wind flow developed, pushing temperatures well above average, especially over the interior.  

During the 22nd and 23rd the strong north-westerly winds were replaced by a vigorous south to westerly stream linked to the passage of a deep low pressure system across southern Australia and an approaching high. The strong winds with the change gathered soil from the long parched central and eastern Australian interior and drove an extensive band of duststorms east, draping towns in it's path in a thick coat of dust. The thick dust spread across the north-east tropical coast during the 24th and 25th.

This was amongst the most significant duststorm events to affect the state for many years, reaching the south-east Gulf of Carpentaria in the north and bringing thick dust to the east coastal areas.  Other recent stand out duststorms in Queensland were in October 2002, October 2003 and February 2005 but this event almost certainly eclipsed those in extent, particulate size and the amount of soil removed and probably equates to some of the biggest duststorm events during major dry El Niņo periods in our history.

As the winds dropped out post event, weather conditions became benign and pleasant until a frontal passage during the 26th and 27th again whipped up widespread dust across southern districts, though this event was much less severe.

Rainfall

The generally dry conditions across Queensland in recent months persisted, with the 3-month period July to September recording 7.31 mm as an area averaged total across the state, this amount only eclipsed by 5.4 mm in 1941 and 6.8 mm in 1929, based on our climate records since 1900.  

This month's rainfall, averaged across the state, was 5.37 mm compared to the long term average of 12.89 mm and the driest September since 2003. Amounts amongst the lowest 10% on record (decile 1) were recorded in parts of the Carpentaria, Western and Central districts.  Only part of the Lower Carpentaria and Central Lowlands and the Fraser Island/Hervey Bay area received above average falls, though it takes only a little rain in this seasonally dry time of the year to be higher than average.

In the far west, Birdsville has only recorded 9.2 mm since February, this typifying the dry conditions through central Australia where the major duststorm event had its origins.

Bellenden Ker Top Station recorded 29.6 mm in September and only 308.2 mm during the 4 months June to September this being the driest on record for the June to September period over 37 years of record.  This location at the top of the range is the wettest location in Queensland with a Bureau rain gauge and the long term average for the June to September period is 1424 mm.

During September only the south-east, spreading west through the Warrego and part of the central interior recorded more than 10 mm of rain with the wettest area being near the Hervey Bay/Fraser Island where a few sites recorded more than 70 mm. A large part of the Western, Carpentaria, Peninsula, Central Highlands and smaller parts of the Central district recorded no rainfall.  

A thundery rain band moved across southern and south-eastern Queensland between the 3rd and 5th and produced moderate falls in the south-east. Showers and thunderstorms during the 7th and early 8th triggered a few falls over 50 mm in the Hervey Bay - Wide Bay area. 

The wettest overall was 82.4 mm at Kingfisher Bay Resort, followed by 69.4 mm at Hervey Bay Airport and 69.3 mm at Sandy Cape Lighthouse.

The driest areas registered no rainfall and included a large part of the Western, Carpentaria, Peninsula, Central Highlands and smaller parts in the Central district.  

Some sites had their lowest total September rainfall on record.

Some sites had their lowest total September rainfall for at least 20 years.

The wettest single day was on the 8th with 65.2 mm at Kingfisher Bay Resort, followed by 51.6 mm at Double Island Point Lighthouse and 49.8 mm at Hervey Bay Airport.

Temperature

The mean temperature averaged across the state was 22.65°C this being 1.35°C above average. Anomalous north to north-west winds over all but the north-east tropical areas contributed to the hotter conditions.  Fifteen locations through the east coast and central interior districts recorded their highest September mean daily maximum temperature on record. 

Maximum temperature

Mean maximum temperatures were hotter than the long term average across the state and the warmest in the last 6 years with the highest anomalies through interior parts of the Central and Port Curtis districts and reaching into the northern Darling Downs being over 3°C. 

Averaged across the state this month was 30.49°C and the sixth highest September mean daily maximum temperature since the start of our area averaged series in 1950 and 1.82°C higher than the average. This is also the hottest September since 2003.  

The 3-month period July to September was 2.42°C higher than the long term average mean daily maximum temperature, this being the highest on record for this period.  

Rockhampton Aero has now broken it's previous high mean daily maximum temperature in 4 consecutive months, June to September. The 4 month mean daily maximum temperature is also a record high at 27.6°C and 3 °C above the long-term mean for the site.  Gladstone Radar and the Gladstone Airport sites have broken their previous high mean monthly maximum temperature in 3 consecutive months. 

Daily maximum temperatures were above average, especially across western areas, between the 13th and 22nd September, peaking on the 21st and 22nd when large areas were more than 10°C hotter than the long-term September average.  Injune recorded 36.7°C on the 21st this being the hottest September day for them in 43 years.

The hottest day was the 21st with 41.0°C at Bedourie Police Station, followed by 40.0°C at Boulia Airport and 39.9°C at Urandangi.

The warmest days on average were 35.7°C at Kowanyama Airport, followed by 35.2°C at Century Mine, 35.2°C at Weipa Aero, 35.1°C at Musgrave and 35.1°C at Scherger RAAF.

The coolest days on average were 21.5°C at Applethorpe, followed by 22.3°C at Stanthorpe Leslie Parade and 23.4°C at Toowoomba Airport.

The coldest day was 15.1°C at Applethorpe followed by 15.7°C at Stanthorpe Leslie Parade, both on the 27th, followed by 16.2°C at Applethorpe on the 28th.

Some sites had their highest September temperature on record.

Some sites had their highest September mean daily maximum temperature on record.

Some sites had their highest September mean daily maximum temperature for at least 20 years.

See a map of mean maximum temperatures. See a map of maximum temperature anomalies.

Minimum temperature

The mean minimum temperature averaged across the state was 14.44°C and 0.88°C warmer than usual.

South-western areas extending east though central parts to the east coast between Cairns and Bundaberg experienced the higher anomalies. 

Many sites broke their previous highest September minimum temperatures during the 22nd and 23rd across western and southern Queensland.  Charleville Aero recorded 25°C on the 22nd and was the highest from a combined record shared with the Charleville Post Office over 121 years.

The coldest night was −2.4°C at Stanthorpe Leslie Parade, followed by −2.1°C at Applethorpe, both on the 1st.

The coolest nights on average were 4.6°C at Stanthorpe Leslie Parade, followed by 5.0°C at Applethorpe, followed by 6.3°C at Warwick.

The warmest nights on average were 24.3°C at Horn Island, followed by 24.1°C at Coconut Island, followed by 23.6°C at Willis Island reflecting the high sea surface temperatures in the north.

The warmest night was 26.5°C at Windorah Post Office on the 22nd, followed by 25.9°C on the 27th and 28th at Horn Island, followed by 25.7°C at Coconut Island on the 27th.

Some sites had their warmest September night (highest daily minimum temperature) on record.

Some sites had their highest September mean daily minimum temperature for at least 20 years.

See a map of mean minimum temperatures. See a map of minimum temperature anomalies.

Duststorms

An upper trough system over the west of the continent moved into south-eastern Australia on the 22nd and then off the coast on the 23rd.  A strong front associated with this system moved across southern and western Queensland.  Hot and gusty north-westerly winds preceded the trough over southern Queensland and were replaced by a vigorous south to westerly stream that developed widespread duststorms over southern and western areas of the state.  Many of the duststorms were severe with visibility reduced to below 200 metres.

An extended period of dry conditions in central Australia and western parts of Queensland and New South Wales provided an ample dust source that culminated in one of the biggest duststorm events in living memory.  Satellite imagery depicted the magnitude of the dust extending across New South Wales and stretching north to the south-east Gulf of Carpentaria and Cape York and spreading across the north-east tropical coast on the 24th and 25th. 

Another frontal passage on the 26th and 27th again triggered duststorms, particularly over western districts where the winds were stronger.  This event was less dramatic but again brought widespread dust to the east coast.

Wind

The most significant wind event was during the duststorm event that swept across the interior during the 22nd and 23rd.

The extent of the area affected by high winds across Australia during this event is thought to be exceptional.

The strongest wind gust was 89 km/h at Ballera Gas Field on the 22nd, followed by 81 km/h at Birdsville Airport also on the 22nd, followed by 78 km/h at Longreach Aero on the 3rd.

Notes

This statement has been prepared based on information available at 10 am on Thursday 1 October 2009. 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 10 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 decile ranking (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.

* These sites use a nearby station for long term comparison.
