Brisbane in February 2015: Above average rainfall; cooler days and nights overall

Rainfall was well above average during February, with the Brisbane Aero and Redcliffe sites recording more than twice the monthly long-term average. Heavy rainfall was recorded between the 20th and 22nd as the remnants of ex-tropical cyclone Marcia affected the southeast. Boondall recorded its highest February rainfall since 1992. 

Both maximum and minimum temperatures were below the long-term average at most sites. Daytime temperatures were warmer than usual at the start of the month before cooler conditions were experienced for most of the month. Warmer than average daytime temperatures returned near the end of February. Overnight temperatures were generally cooler than average up to the 18th, until warmer conditions returned and remained until the end of the month.

  • Well above average rainfall
  • Cooler than average daytime temperatures
  • Cooler than average overnight temperatures

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 3 pm on Sunday 1 March 2015. 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.
