Western Australia in winter 2014: third warmest winter on record

Winter 2014 saw below to very much below average rainfall in southern, central, and western WA, with record low rainfall totals reported in the southern Gascoyne, Central West, and Great Southern. Above average rainfall was mainly confined to the Kimberley as a result of unseasonal heavy rainfall in July. When averaged across the State, winter 2014 ranked as ninth driest since records commenced in 1900. The Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay) also recorded below average rainfall for winter 2014, whilst it was the sixth driest winter on record for the South West Land Division (SWLD) as a whole.

Mean maximum temperatures were above to very much above average in western, central, and southern WA in winter 2014, with highest on record mean maxima reported in the SWLD, west Gascoyne, and west Pilbara. Mean maxima were 2 °C to 4 °C warmer than normal in the Gascoyne, whilst most of the Kimberley, east Pilbara, and Northern Interior saw near average mean maximum temperatures. The statewide average mean maximum temperature was 1.2 °C above average and ranked as the equal third warmest winter since records commenced in 1910. For the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay) winter 2014 ranked third warmest winter on record, following the seventh warmest winter last year, and sixth warmest in 2012.

Mean minimum temperatures were above to very much above average in the southwest Gascoyne, much of the South West Land Division, and eastern Eucla, with mean maxima generally up to 1 °C warmer than normal. Much of the Kimberley, inland east Pilbara, Northern Interior, and parts of the Goldfields and Southern Interior saw below to very much below average mean minimum temperatures, with temperatures between 1°C and 3 °C cooler than normal in parts of the Kimberley. When averaged across the State, the mean minimum temperature was near average, whilst for the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay), winter 2014 was above average in terms of the mean minimum temperature.

  • Daily rainfall of 215.0 mm at Cape Leveque on 13 July was the highest daily rainfall in winter in 88 years of record at the site, and the highest daily rainfall in July in WA on record.
  • The two-day rainfall total of 242.0 mm on 12 and 13 July at Cygnet Bay (no other rain fell at Cygnet Bay during winter 2014) was the highest winter rainfall total for the site in 51 years of record.
  • Several sites in the Southeast Coastal, including Esperance, received their highest daily rainfall on record for winter on 8 July as a result of the passage of a strong frontal system.
  • Very warm condtions in western and southern WA during August resulted in a number of stations recording their highest winter maximum temperature on record, including Cape Leeuwin with a maximum of 24.7 °C on 6 August, its highest winter temperature in 108 years of record. Meanwhile, Carnarvon Airport broke its previous highest winter temperature in 68 years of record (31.8 °C on 4 June 1975) on five occasions during winter 2014 (32.2 °C on 5 June, 33.6 °C 12 August, 33.1 °C 13 August, 33.1 °C 25 August, and 32.0 °C 28 August).
  • On 1 June, Troughton Island in the north Kimberley broke both its minimum and maximum temperature records for June. The minimum temperature of 27.3 °C was the highest minimum temperature on record for June in Australia, exceeding the previous record of 27.2 °C at Cockatoo Island (northeast of the Dampier Peninsula in the Kimberley) on 1 June 1971, and the second highest minimum temperature on record in Australia in winter, just falling short of a minimum of 27.5 °C at Cadjebut in the Kimberley on 26 August 1998.

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 12 pm on Monday 1 September 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.
