Monday, 2 November 2009 - Monthly Climate Summary for Queensland - Product code IDCKGC24R0
Rainfall overall was below the long term average across most of the state. Only parts of the southern and central interior, and the western Peninsula received above average rainfall.
Area averaged across the state and based on records since 1900, the October rainfall was 12.62 mm. The long term average for October is 26.18 mm
The first significant rainfall occurred on the 4th, where isolated afternoon showers and thunderstorms over the interior of Cape York Peninsula produced some locally heavy falls and high wind gusts. At 9am on the 5th, Scherger RAAF recorded 66 mm and Weipa recorded 39 mm. Weipa also recorded a maximum wind gust of 120km/hr, which was the strongest recorded wind gust for October.
An upper trough over south east Queensland produced some patchy thundery rain about the south east corner on the 11th, with daily totals ranging from 20 mm to 30 mm.
An eastward moving trough lying over the south western districts brought isolated showers and thunderstorms to the south east interior and coast on the 12th. Showers and gusty thunderstorms also occurred in the central districts and over the south eastern corner of the state on the 13th. Small hail was reported at Toowoomba, and at some Brisbane and Gold Coast suburbs. Wind gusts exceeded 90km/hr in Brisbane and bay side suburbs.
On the 18th, some isolated showers occurred along parts of the east coast, with isolated thunderstorms over the south east corner. Fresh to strong onshore south easterly winds produced falls of around 40 mm in the south east, and around 60 mm in the exposed central and north coast areas.
The combination of a surface trough extending from the Northern Territory into south east Queensland, and an upper level trough located over the southern interior on the 26th, resulted in a thundery rainband over parts of the southern and south east interior, and the south east corner of the state. Rainfall totals ranged from around 10 mm to 20 mm in the Maranoa and Warrego, the Darling Downs and in southern coastal areas. Around 30 mm to 60 mm fell over the Wivenhoe and Somerset dams, with totals increasing to around 80 mm to 100 mm in the Pine and Caboolture areas.
From the 27th to 29th numerous thunderstorms continued to
develop over the state's interior east of the surface trough that
extended from the Gulf to the southern interior. Three day rainfall
totals ranged from 20 mm to 70 mm over the Maranoa and Warrego, the
Central West and the Central Highlands districts. Some stations
had their highest October daily rainfall on record and their highest total October rainfall on record. A
high pressure system over the Tasman Sea directed an easterly flow that
also generated isolated showers over the east coast, and rain
areas along the tropical east coast. Three day rainfall
totals ranged from around 80 mm to 160 mm in the area.
Mean maximum temperatures were generally above the long term average in the eastern half of the state, and below average in the west. Area averaged across the state, and based on records since 1950, the maximum temperature was 32.25°C, while the long term average is 31.99°C.
Some sites had their highest October mean daily maximum temperature on record.The hottest day was 41.5°C at Birdsville Airport on the 24th, followed by 41.0°C at Bedourie Police Station on the 25th, followed by 40.9°C at Thargomindah Airport on the 22nd.
The warmest days on average were 36.9°C at Kowanyama Airport, followed by 36.7°C at Normanton Airport, followed by 36.4°C at Century Mine, followed by 36.4°C at Croydon Township.
The coolest days on average were 23.2°C at Applethorpe, followed by 23.9°C at Stanthorpe Leslie Parade, followed by 24.7°C at Cape Moreton Lighthouse.
The coldest day was 13.4°C at Stanthorpe Leslie Parade on the 11th, followed by 14.8°C at Applethorpe on the 11th, followed by 18.0°C at Maleny Tamarind St on the 11th.See a map of mean maximum temperatures. See a map of maximum temperature anomalies.
Mean minimum temperatures were below the long term average across most of the state, with the largest anomalies in western districts. Area averaged, and based on records since 1950, the minimum temperature for the state was 16.27°C, where the long term average is 17.33°C.
A complex low pressure system was located off the New South Wales coast on the 7th and 8th. A trough extended north from this low through to eastern Queensland and into the Gulf Country. To the west of the trough a large high in the Great Australian Bight directed cool, dry south west to south east winds as far north as Burketown, and produced well below average minimum temperatures. Some sites had their lowest October temperature on record.
The coldest night was −1.5°C at Stanthorpe Leslie Parade on the 17th, followed by −1.1°C at Applethorpe on the 17th, followed by −0.6°C at Stanthorpe Leslie Parade on the 8th.
The coolest nights on average were 8.1°C at Stanthorpe Leslie Parade, followed by 8.6°C at Applethorpe, followed by 10.0°C at Kingaroy Airport. Some sites had their lowest October mean daily minimum temperature on record.
The warmest nights on average were 24.8°C at Horn Island, followed by 24.6°C at Coconut Island, followed by 23.7°C at Willis Island.
The warmest night was 27.0°C at Ingham Composite on the 31st, followed by 26.8°C at Birdsville Airport on the 31st, followed by 26.5°C at Thargomindah Airport on the 25th.See a map of mean minimum temperatures. See a map of minimum temperature anomalies.
The strongest wind gust was 120 km/h at Weipa Aero on the 4th. Strong wind gusts were also recorded on the 13th, with 94 km/h at Cape Moreton Lighthouse and 93 km/h at Brisbane.
Areas of raised dust were reported over the southern and south west parts of Queensland on the 13th following the passage of a surface trough. Dust haze extended to the south east coast on the 14th.

This statement has been prepared based on information available at 7 am on Monday 2 November 2009. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Please note that the rainfall data from Bureau of Meteorology telemetry
gauges (those with ALERT, AL or TM in their names) includes real-time
operational data from automated systems and has not been checked.
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. *In this case, averages from a nearby suitable
site have been used instead (these are marked with an *).
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.
