Rainfall

Extreme rainfall and flooding affected parts of Queensland including the Brisbane metropolitan area in the last week of January when the remnants of ex-tropical cyclone Oswald passed by, as discussed in Special Climate Statement 44. Logan City had its wettest January day (with 192.5 mm in the 24 hours to 9 am on the 28th) and its wettest January with 1395.2 mm (although records from there only go back to 1993). February and April also brought well above average rain, and above-normal totals were seen in March, June and July. By contrast, Brisbane Airport had no rain at all in August, and October was also quite dry.
Overall, rainfall for 2013 was slightly above average at all sites in the Brisbane area.

Daytime temperatures around Brisbane were generally below average from February to June: Brisbane Airport reached only 13.3 °C on 21 June. Days were much warmer than normal from August to October and then in late December, hot conditions across the Brisbane metropolitan area saw Amberley reach 40.4 °C on 29 December, the highest recorded temperature for 2013 in the Brisbane metropolitan area.  Amberley also had the warmest days on average, with 27.4 °C.
Averaged over the year, daytime maximum temperatures were above average at most locations.

Minimum temperature

Overall, overnight minimum temperatures were above average for most sites around Brisbane. Most months were warmer than normal by night, but there were plenty of individual cold nights. The coldest nights were at Amberley with -1.4 °C on 21 August, -1.1 °C on the 22nd and -0.5 °C on the 23rd.

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 7 pm on Wednesday 1 January 2014. 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 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.
