Brisbane in October 2010: A cool, wet month

  • More than 200% of October average rainfall
  • Below average maximum temperatures
  • Flash flooding on the 11th in creeks and streams, including at Toombul, Carseldine and Boondall  

Rainfall

On the 7th, a thundery rain band moved across southern Queensland.  Instability increased ahead of a trough over the interior and isolated afternoon showers and thunderstorms developed over most inland areas, extending to the coast in the southeast.  

Overnight on the 8th and into the early morning of the 9th an upper trough combined with a strong southeasterly change caused heavy rain areas over the Sunshine Coast and Hinterland.  On the 9th, an intensifying high pressure system over the southern Tasman Sea and a trough near the south coast increased winds along the southeast coast overnight and into the 10th, with increasing rainfall.  The systems produced wind gusts in excess of 90 km/hr, mainly along the exposed coast and over the islands. Strong to gale force winds onto the south coast maintained very rough seas and large swells leading to dangerous beach and surf conditions.  Flash flooding occurred on the 11th in creeks and streams, including at Toombul, Carseldine and Boondall.  The spillway gates at North Pine Dam, northwest of Brisbane were opened in response to the heavy falls.

The wettest overall was 397.0 mm at Redcliffe, followed by 350.0 mm at Brisbane Aero, followed by 306.4 mm at Brisbane.

Some sites had their highest total October rainfall for at least 20 years.

The wettest single day 126.4 mm at Redcliffe on the 11th, followed by 112.4 mm at Brisbane Aero on the 11th, followed by 93.6 mm at Brisbane on the 11th.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Greater Brisbane 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 3 pm on Monday 1 November 2010. 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 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.

* The data for October 2010 at this site has been compared to another nearby site with a longer record.
