Brisbane in October 2014: Very little rainfall, hot days

October rainfall in the Brisbane area was very much below average for all sites, with some places recording their lowest October rainfall on record. Most sites, except for Brisbane Aero and Redcliffe, only recorded two rain days. Brisbane Aero had record low monthly rainfall and only had four rain days, equalling the lowest number of rain days on record for October (the long-term average for October is 8 to 9 days of rain). Thunderstorms occurred on the 13th and into the early morning of the 14th, and again on the evening of the 27th resulting in the bulk of the monthly rainfall. The highest daily rainfall was recorded at Redcliffe on the 18th, with 15.6 mm.

Mean maximum and mean minimum temperatures were above average for most sites. Amberley and Archerfield recorded more than 1 °C above average for mean maxima, and Redcliffe equalled its long-term average, while other sites were slightly above average for the month. Mean minima were less than 1 °C above average for all sites except Amberley, which had cooler than average overnight temperatures. The hottest days were recorded on the 27th and 28th, with all sites recording maximum temperature several degrees above average. On the 27th, Amberley had its highest October temperature on record in 74 years, with 41.3°C (11 °C above the October average).

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in 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.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 7 pm on Saturday 1 November 2014. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites 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.

The ACORN-SAT dataset is used for temperature area averages.
