Rainfall

Rainfall during summer 2011/12 was above to very much above average across most of WA, apart from small isolated areas where below average rainfall was recorded, most notably in the Eucla and southeast Goldfields, and north and east Kimberley. When averaged across the state as a whole, rainfall for summer 2011/12 was above average, mostly due to above average rainfall during December 2011, particularly in the southern half of the state, and the 6th wettest January on record for the state. February rainfall was near average for the state as a whole.

Rainfall in the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay) during summer 2011/12 was very much above average and ranked as 10th wettest since comparable records commenced in 1900, largely due to the Lower Southwest recording its 2nd wettest December on record in 2011, but also above average rainfall in January 2012. Several sites in the western Great Southern, Lower West, and Central West observed their wettest summer on record. The Southwest Land Division (SWLD) as a whole as reported above average summer rainfall in 2011/12.

Significant rainfall events during summer 2011/12

• A deep middle level trough off the west coast produced the first significant summer rainfall in the SWLD and the adjacent Goldfields and Gascoyne on 6 December 2011. Numerous sites in the Lower West, Central Wheat Belt, and Great Southern observed over 50 mm during the event, though the heaviest downpours occurred in the eastern Central Wheatbelt and northeast Great Southern. Daily rainfall totals of 109.0 mm at Amrista Park and 105.0 mm at Hyden, both in the northeast Great Southern, in the 24 hours to 9am on the 7th were their wettest days on record and in the top ten highest December daily falls on record in the SWLD. A few other sites in the southern Central Wheat Belt also broke their previous wettest summer day on record on the 7th.
• Another deep mid-level trough off the west coast brought further widespread moderate to heavy rainfall across the SWLD and the adjacent Goldfields and Gascoyne on the evening on the 12th and into the morning of 13 December 2011, with numerous sites in the SWLD and Gascoyne observing their highest December daily rainfall on record. Areas in the Great Southern were hit hardest by the downpour, and the daily total of 125.6 mm at Williams in the Great Southern in the 24 hours to 9am on the 13th was not only their wettest December day in 115 years of record, but also the highest daily rainfall recorded in December in the SWLD. Dwarda Downs in the northwestern Great Southern observed its wettest summer day on record. For more details of these two extreme heavy rainfall events, please see Special Climate Statement 35.
• Tropical Cyclone Heidi crossed the Pilbara coast near Port Hedland on 12 January 2012 and moved in a generally southerly direction after landfall, bringing very heavy falls to the east Pilbara and west Kimberley, and unconfirmed reports of totals over 300 mm near the TC path. Several January daily rainfall totals were broken, and Carlindie recorded its wettest summer day on record with 130.0 mm in the 24 hours to 9am on the 12th.
• A surface trough near the west coast produced slow moving thunderstorms in western parts of WA on the 20th January 2012, particularly in the Perth Metropolitan area. Several sites in the Perth hills broke their daily rainfall record for January in more than 100 years of record, whilst Serpentine broke both its daily and monthly record for January with a single daily fall of 60.6 mm.
• A very active monsoon over northern WA in association with Tropical Cyclone Iggy northwest of the Pilbara coast brought a very wet spell to parts of the Pilbara and Kimberley between 26 and 29 January 2012. Cygnet Bay and Cape Leveque in the west Kimberley both recorded 4 consecutive days of rainfall over 100 mm. Such a sequence of four consecutive days over 100 mm had not been recorded before in WA. The daily fall of 239.8 mm on the 27th at Cape Leveque was its wettest summer day on record, while the 206.8 mm at Cygnet Bay on the 26th was its highest daily total for January on record. The passage of ex-TC Iggy through northern parts of the SWLD early in February brought heavy rainfall to the northern Lower West, southern Central West and Central Wheat Belt. Dandaragan West observed its wettest summer day an record in the 24 hours to 9am on the 3rd.

Maximum temperature

Mean daily maximum temperatures during summer 2011/12 were below to very much below average over much of central WA, with areas of up to 3 °C below normal in the northern Goldfields and eastern Interior. Above to very much above average daytime temperatures were observed in western WA from the Gascoyne to the Southwest, and in the west and north Kimberley, with small areas of up to 2 °C above normal mean maxima around the southwest Capes, the Shark Bay area of the Gascoyne, and the Dampier Peninsula and King Sound region in the west Kimberley. When averaged across the state, the mean maximum temperature for WA during summer 2011/12 was below average, however, the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay) saw above average daytime temperatures. Cape Naturaliste observed its hottest summer in 107 years of record after observing very much above average December maxima and its hottest January on record, whilst not a record at Cape Leeuwin, summer 2011/12 was its hottest for over 100 years. Pemberton and Jurien Bay recorded their hottest summers on record.

Extremely hot weather was observed in the Pilbara from 20 to 25 December 2011, with numerous sites observing daily maxima over 47 °C, and several sites registering record high December temperatures. The December maximum temperature record for WA was broken on three consecutive days, with Roebourne (49.4 °C on the 21st), Roebourne Airport (49.0 °C on the 21st), Onslow (49.2 °C on the 22nd), and Learmonth Airport (48.9 °C on the 23rd), all surpassing the previous December record for WA of 48.8 °C set at Mardie on 26 December 1986. To further illustrate the significance of the event, Roebourne's 49.4 °C was the 2nd hottest December day on record in Australia, just 0.1 °C below 49.5 °C recorded at Birdsville in Queensland on 24 December 1972, and the equal 5th hottest day on record in WA. Sites in WA have recorded temperatures at or above 48 °C during December on 19 occasions, and 10 of those occurred during this event. For more details of this extreme temperature event, please see Special Climate Statement 37.

A number of hot spells were experienced in western parts of WA during summer 2011/12. The most notable hot spell was in the latter part of January when many sites registered four or more consecutive days with daily maxima over 35 °C. Jurien Bay in the Central West experienced eight consecutive days with daily maxima over 35 °C, equalling its longest hot spell on record (20 to 27 January 1976 and 16 to 23 February 1995).

Minimum temperature

Minimum temperatures were above to very much above average during summer 2011/12 in western and southern parts of WA, with mean minima up to between 2 °C and 3 °C above normal in west coast districts, and a number of sites in the Southwest, South Coastal, Lower West, Great Southern, and Central West observed their warmest summer on record. Below to very much below average overnight temperatures were observed in the west and south Kimberley, far east Pilbara, Interior, east Gascoyne, and northern Goldfields, with areas up to 3 °C cooler than normal in the western central Interior. When averaged across the state, the mean minimum temperature for WA during summer 2011/12 was near average, however, the Lower Southwest experienced its 3rd hottest summer on record after the 4th hottest December, the hottest January, and an above average February (comparable records commenced in 1950). The 3rd warmest summer for the Lower Southwest follows the Lower Southwest's warmest year on record in 2011, and its warmest summer on record in 2010/11.

Notable Events

• Three tropical cyclones occurred in the WA region during summer 2011/12l; TC Alenga (5-9 December) remained off well to the east of WA, TC Heidi (10-12 January) crossed the coast early on the 12th just to the east of Port Hedland as a category 2 system causing mostly minor damage and some flooding in the east Pilbara, TC Iggy (26 January - 2 February) remained off the WA west coast, though the weakened tropical low crossed the Central West coast bringing heavy rainfall and near gale force winds.
• On 4 January 2012, a surface trough extending across northern parts of the SWLD to a low pressure system to the west of the Lower West produced thunderstorms over much of the SWLD and adjacent southern Gascoyne and Goldfields, with reports of large hail and damaging wind gusts. Significant damage to houses was reported in Kalannie, Ejanding, and Northam, in the Central Wheat Belt, primarily due to the strong winds. Paynes Find in the southern Gascoyne reported hail up to 3 cm during the evening.
• A surface trough combined with a mid-level disturbance to the west of the state to cause significant thunderstorm activity in the SWLD and adjacent Gascoyne on 20 January. Thunderstorms began early morning and continued into the afternoon, with the majority of the activity in the metropolitan area clearing during the morning. A number of stations across the northern SWLD and adjacent Gascoyne reported heavy rainfall, particularly in the Lower West. There were numerous requests for help from the SES, mostly dealing with water damage, localised flash flooding, and fallen trees, with the majority of calls received from Mandurah, Rockingham, and the Swan region. Several areas in the Perth region lost power as frequent lightning strikes were a feature of the storms over southern suburbs. Four people were reported to have been struck by lightning, however, none of their injuries were life-threatening.
• A surface trough produced afternoon thunderstorms through parts of the Gascoyne and SWLD on 20 February 2012. Koorda in the Central Wheat Belt reported flash flooding and power lines down.
• A mid-level trough combined with a strong surface easterly pressure gradient produced an area of rain and thunderstorms through the Central Wheat Belt and the Great Southern from early morning on 28 February 2012. Roads were damaged by flash flooding near Cuballing.
