Brisbane in spring 2015: Near-average rainfall and temperatures overall

Spring rainfall in the Brisbane metropolitan was near-average. Both daytime and overnight temperatures where within 1.0 C of the long-term average at all metropolitan sites.

  • Near-average spring rainfall in Brisbane
  • Daytime temperatures near-average; western suburbs slightly warmer
  • Overnight temperatures near-average; slightly cooler in western and coastal locations
  • Severe thunderstorms throughout the season

Spring rainfall in the Brisbane metropolitan area was near-average at all locations, except Amberley. Amberley received nearly one and a half times its average seasonal rainfall, with a majority of the spring total attributed to severe thunderstorms traversing across the western suburbs. Severe thunderstorms throughout the season produced some significant rainfall totals, however, the highest daily total for spring was recorded in the 24 hours to 9am on the 30th November at Amberley, with 57.4 mm. 

Both mean maximum and mean minimum spring temperatures were near-average. Mean maxima tended warmer than average in locations in the western suburbs of Archerfield and Amberley, while daytime temperatures were slightly below-average at the coastal locations of Redcliffe and Brisbane Airport. 

Mean minima were slightly cooler than average at the coastal and western locations of Redcliffe and Amberley respectively, and slightly warmer than average at remaining locations. The coldest spring day occurred at the start of the season on 2 September, where all locations recorded overnight temperatures that were 6 C to 8 C below average. 

Severe thunderstorms affected the Brisbane area throughout the season, and the most notable occurring on 29 November. Large hail, damaging winds and heavy rain was recorded in southern suburbs of Brisbane. Hail up to 4 cm in diameter was reported from numerous suburbs of Brisbane, including Acacia Ridge, Archerfield, Forest Lake and Rocklea.

Notes

The Seasonal climate summary lists 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.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 9 am on Tuesday 1 December 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.
