Brisbane Metro in 2010: A very wet year

Rainfall was above average in the Brisbane Metro area during 2010 with most stations recording the highest 10% on record. Based on area averaged data maps of the state, the Brisbane area had more than 400 mm above the long term average. Brisbane City recorded the highest annual total since 1974. The generally increased cloudiness associated with the high rainfall was ‘reflected’ in the lower average temperatures. Average maximum temperatures were a little lower than the long term average and minima close to a degree higher than average.


Rainfall

Brisbane City recorded 1658.6 mm in 2010 this being the highest annual total since the current site opened late in 1999 and with reference to the previous city gauge with a record from 1840 to 1994, was the highest since the big flood year of 1974 when 2193.7 mm was recorded. The highest annual total on record was recorded in 1893 with 2242.4 mm and it was also a big flood year. 

January rainfall was generally lower than average in the metro area. February and March saw a return to higher rainfall. April to July tended drier than average followed by a very wet August to October and an exceptionally wet December.

Notes

A Annual Climate Summary is prepared to list the main features of the weather in Brisbane Metro 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 12 pm on Tuesday 4 January 2011. 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.

* These sites are compared to other long-term sites in the area using the 1961 to 1990 period where available for Brisbane temperature, the 1981 to 2004 for Redcliffe temperature and all years of record for rainfall.

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.

Information for the 'Selection of significant events' was obtained from the Disaster Mitigation section of the Queensland Regional Office of the Bureau of Meteorology.
