Brisbane in April 2016: Dry month; warm days and nights

Rainfall during April was well below average, record low at some locations. Both mean maximum and mean minimum temperatures were well above average.

  • Very dry month in Brisbane metropolitan area
  • Warm mean maximum temperatures
  • Warm mean minimum temperatures
  • Warmest April on record at some locations

Rainfall was well below average at all locations in the metropolitan area, and Brisbane Aero had its lowest April rainfall on record. Very little or no rain fell in the metropolitan area until the middle of the month. On the 13th, a moist onshore southeasterly flow produced isolated shower activity to the greater Brisbane area until the 16th. Light to moderate rainfall totals were recorded at all metropolitan sites. From the 25th, moist onshore flow again resulted in light falls about the metropolitan area.

Both mean maximum and mean minimum temperatures were well above average at all metropolitan sites.

The first half of the month saw much warmer than average daily maximum temperatures recorded at all metropolitan locations. Between the 12th and 16th, periods of showers kept temperatures slightly cooler than usual, before a return to near average temperatures until the end of the month. As a result of the warmth, several locations had their highest April mean daily maximum temperature on record

Likewise, there were warmer than usual overnight temperatures recorded in the first half of the month. Mid-April saw cooler overnight temperatures, as rain fell across much of the metropolitan area. Warm nights were recorded between the 18th and 25th, before a return to near-average minimum temperatures for the remainder of the month. Some sites had their highest April mean daily minimum temperature on record.

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 9 am on Monday 2 May 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.
