Brisbane in March 2015: Near-average rainfall; warm days and nights in the metropolitan area

It was an exceptionally warm month in the Brisbane metropolitan area, with a particularly hot spell on the 5th. A slow-moving surface trough approached from the west of the State on the 4th, and extended hot conditions into the southeastern interior the following day, with the heat felt in the southeast and Brisbane on the 5th as the trough shifted eastwards. There was more hot weather on the 19th. Most sites in the Brisbane area had mean daytime maximum and overnight minimum temperatures between 1 and 2 degrees above average.

Rainfall totals were mixed, but all sites recorded near-average or slightly above-average totals for March. The combination of a slow-moving surface trough extending over the interior of the State and an upper level trough over southeast Queensland on the 21st generated widespread rain across the metropolitan area; almost 150 mm of the 161 mm received in Brisbane City during March was in the 48 hours to 9am on the 23rd. Thunderstorms occurred on the 25th across Brisbane, with some isolated, heavy falls recorded at some sites.

  • Average rainfall recorded at all Metropolitan sites
  • Some hot days
  • Warmer than average daytime temperatures
  • Warm nights overall

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 10 am on Wednesday 1 April 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.
