Brisbane in January 2016: Hot days at the end of the month

It was very hot at the end of the month across the metropolitan area, along with persistent warm nights during much of the last week. Rainfall totals were below average at all metropolitan sites.

  • Hot days at the end of the month
  • Warm nights during most of the last week
  • Rainfall below average at all metropolitan sites

Rainfall was below average at all metropolitan sites during January. Rainfall totals exceeded 70 mm at all sites, with isolated locations recording in excess of 100 mm, including Boondall with 118.2 mm. Many of the larger daily totals occurred in the first week of January, due to a deep surface trough extending into the southeast providing ample moisture for moderate shower activity. Thunderstorms formed across the metropolitan area on the 23rd, 26th, 28th, 29th and 30th, and brought isolated falls to most metropolitan sites, though mostly light falls were recorded.

Mean maximum temperatures were slightly above average for January at most metropolitan sites. Relatively cool days were experienced at the start and middle of the month, with some very warm days near the end of the month. The hottest day occurred on the 29th, where Archerfield reached 36.3 C.

Mean minimum temperatures were below average for January at all metropolitan sites. During the first three weeks of the month, overnight temperatures were below average, with the coolest nights occurring mid-month. During much of the last week of January, overnight temperatures were persistently warmer that usual, providing little relief from the hot days across Brisbane.

Notes

The Monthly 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 10 am on Monday 1 February 2016. 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.
