Warmer than normal minimum temperatures were observed from northern to eastern parts of the State. A wet June was reported in the northwest, inland and eastern WA, but large parts of the South West Land Division recorded below average rainfall.

Wet in the northwest, below average rainfall in the southwest

  • Two slow moving cloudbands produced rainfall from WA's northwest to southeast both early and late in the month, with notable heavy falls in the Pilbara on the 7th. A number of sites had their highest total June rainfall for at least 25 years
  • In the southwest, widespread moderate rainfall on the 6th-7th,12th-13th and 28th was associated with lows near the State's south coast, however monthly rainfall was generally below average
  • With much of WA from the northwest to the eastern desert lands having a wet month, total rain for Western Australia was approximately 46% above normal

Note: Observations for “Perth Metro” are taken from the current site at Mount Lawley (Bureau number 009225).
Comparisons are made against combined data from the current site (which opened in early 1993) and the previous site at Perth Regional Office (009034), which ran from 1876 to early 1992.

Notes

The Monthly climate summary lists the main features of the weather in Western Australia 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 Friday 1 July 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.

Observations for “Perth Metro” are taken from the current site at Mount Lawley (Bureau number 009225).
Comparisons are made against combined data from the current site (which opened in early 1993) and the previous site at Perth Regional Office (009034), which ran from 1876 to early 1992.

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.
