Western Australia in autumn 2014: Eighth warmest autumn on record

Autumn 2014 saw warmer than normal daytime and night time temperatures for most of WA. The statewide average mean maximum temperature was 1.1 °C above average and ranked as the eighth warmest autumn since comparable records commenced in 1910. For the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay), autumn 2014 was above average in terms of maximum temperature, and ranked eighth warmest on record for minimum temperature. Rainfall for WA as a whole, as well as the Lower Southwest and the Southwest Land Division (SWLD), was near average in autumn 2014 due to a dry March and a wet April and May.

  • A mid-level trough combined with ex-tropical cyclone Jack off the WA west coast from 25 to 27 April to produce widespread moderate to heavy rainfall in the west Pilbara, Gascoyne, Central West, Central Wheat Belt, and Great Southern, with Amrista Park and Mordetta in the Great Southern recording their highest autumn daily rainfall on record on the 27th. Flash flooding was reported on the North West Cape as Exmouth recorded 206 mm on the 27th, and also in parts of the Central Wheat Belt, including near Quairading. Partly as a result of this event and a second heavy rainfall event in the first half of May, Learmonth recorded its wettest autumn on record.
  • A very wet end to April and a wet May in the Lower Southwest saw Ferguson Valley record its wettest autumn in 39 years.

Notes

A Seasonal Climate Summary is prepared to list 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, 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 Tuesday 3 June 2014. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages 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.
