Rainfall
Rainfall during summer 2012-13 was above to very much above average in the west Kimberley, Pilbara, western Northern Interior, Gascoyne, and northern and western parts of the Southwest Land Division (SWLD). Below to very much below average rainfall was confined to pockets in the north and east Kimberley, eastern parts of the Southern Interior and Eucla, and the Southeast Coastal.
Averaged across WA as a whole, summer rainfall was above average for the State, mainly as a result of a wet December followed by near average rainfall for WA in January and February. The Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay), as well as the SWLD, also recorded an above average summer rainfall, largely due to some extreme falls in December and above average rainfall in January.
Two heavy rainfall events in the SWLD in the first half of December 2012 were notable as sites registered record daily rainfall for summer. A deep surface trough across northern and western WA combined with a middle level disturbance to the west brought showers and thunderstorms to much of northern and western WA on the 5 and 6 December 2012. North Stirlings in the Great Southern district recorded daily rainfall of 81.8 mm on the 6th, which was its wettest summer day in 54 years of record. A few days later, a deep surface trough interacted with a slow moving middle level low off the WA west coast to produce widespread showers and thunderstorms across most of WA from the 10th to 13th. The heaviest rainfall was reported during the 24 hours to 9am on the 13th with the highest fall being 210.8 mm at Yourdamung Lake, northeast of Collie in the Southwest district. This was the fifth highest daily rainfall total on record in the SWLD for any month. Please refer to Special Climate Statement 42 for further information. Collie in the Southwest district recorded a daily total of 157.2 mm on the 13th, which was its wettest summer day in 110 years of record. Burekup in the Lower West also received 92.0 mm on the same day, more than twice the amount of its previous daily record for summer in 61 years of record.
Tropical cyclones Mitchell and Narelle moved through WA waters during late December and early January respectively, but neither had a significant impact on WA rainfall during summer 2012-13. Tropical cyclone Peta moved over the central Pilbara coast as a category one system on 23 January and brought some localised heavy falls, the highest daily total being 261.6 mm at Hooley on 24 January. Flooding impacts were generally localised and mostly minor. Severe tropical cyclone Rusty brought heavy rainfall to the east Pilbara and west Kimberley in the last week of February, with the highest daily fall during the event being 263.4 mm at Bamboo Creek in the east Pilbara on the 28th, although the rain gauge overflowed so the actual total was likely higher than this. Major flooding of the De Grey river was reported as a result of the slow moving severe tropical cyclone.
Maximum temperature
Mean daily maximum temperatures during summer 2012-13 were above to very much above average throughout southern half of WA, as well as in the west Kimberley, west Pilbara, and the eastern Northern Interior, as mean maxima in the Shark Bay region of the west Gascoyne were up to 4 °C above normal during summer 2012-13. Several sites along the WA west coast recorded their hottest summer on record including Carnarvon, Geraldton, Jurien Bay, Perth, Manjimup, and Pemberton, whilst Ongerup in the South Coastal also broke its summer record.
When averaged across the state, the mean maximum temperature for summer 2012-13 ranked as 10th highest on record from comparable records back to 1910. The Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay) recorded its second hottest summer on record, as a result of recording its sixth hottest December, an above average January, and the fifth hottest February. The summer of 2012-13 in the Lower Southwest was only slightly behind the summer of 2009-10, the hottest on record.
Record high summer temperatures occurred in the first half of January across inland central and eastern WA as a significant heatwave was reported across inland Australia (see Special Climate Statement 43 for details). A number of sites in the southern Gascoyne, Goldfields, Eucla, and Southern Interior registered record high summer temperatures on 3, 8, 9, and 16 January, and the highest summer temperature recorded in WA occurred during this event with 49.0 °C at Leonora on the 9th, the highest temperature recorded in the town in 57 years of record. In contrast, the passage of tropical cyclone Rusty east of Port Hedland late in February brought relatively mild temperatures to the region as a result of overcast conditions, high winds, and heavy rainfall. Port Hedland Airport recorded its mildest summer day in 65 years of record with a maximum of 23.9 °C on the 27th.
Minimum temperature
Minimum temperatures were above to very much above average through much of WA in summer 2012-13, though large parts of the Kimberley, southeast Pilbara, and northeast Gascoyne recorded near average mean minimum temperatures. Mean minima were up to 3 °C above normal in the west Pilbara, and parts of the Northern and Southern Interior, and a number of sites in the west Pilbara, Great Southern, South Coastal, and Southern Interior recorded their warmest or equal warmest summers on record in terms of minimum temperatures.
When averaged across the state, the mean minimum temperature for WA for summer 2012-13 was very much above average, and ranked as the fifth highest since comparable records commenced in 1910. The Lower Southwest similarly was very much above average and recorded its fourth warmest summer in terms of overnight temperatures.
An unusually warm night was recorded across large parts of southern WA on 7 and 8 January following a hot day on the 7th, with cloud over the region and warm northeasterly winds. Merredin in the Central Wheat Belt, and Jarrahwood and Cape Leeuwin in the Southwest recorded their highest summer minimum temperatures in the 24 hours to 9 am on the 8th. Cape Leeuwin recorded a minimum of 24.2 °C, its highest summer minimum temperature in 107 years of recording, and second highest minimum for any month, only behind 24.4 °C recorded on 3 March 1961.

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.
This statement has been prepared based on information available at 2 pm on Friday 1 March 2013. 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.
The ACORN-SAT dataset is being used for temperature area averages from December 2012 onwards. The major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, rather than 1950, and hence rankings are calculated using a larger set of years.
