Rainfall

Summer 2010/11 rainfall was above to very much above average over most of Western Australia, with many sites in the Kimberley, Pilbara, Gascoyne, northern parts of the Southwest Land Division (SWLD), Goldfields, far southern Interior and Eucla observing their highest summer rainfall totals on record. When averaged across the state, rainfall during summer 2010/11 ranked as the 2nd highest on record, only behind 1999/2000. Comparable records began in 1900. The wet conditions were primarily due to an active monsoon over the north of the state for much of the season, with fairly consistent falls across each of the summer months, as a result of one of the strongest La Ninas on record. Above average rainfall was also observed in the Lower Southwest (southwest of a line from Jurien Bay to Bremer Bay), mainly due to above average rainfall during January 2011.

Kuri Bay in the Kimberley recorded 1540.4 mm during January 2011, which is the highest monthly rainfall total ever recorded in WA, breaking the previous record of 1321.7 mm set at Roebuck Plains in the Kimberley in January 1917. In addition to the wettest month on record, Kuri Bay also observed WA's 5th highest two-day rainfall total, with 617.4 mm on the 10th and 11th (228.8 mm and 388.6 mm respectively); and WA's 9th highest three-day rainfall total with 675.4 mm on the 10th, 11th and 12th (228.8 mm, 388.6 mm and 58.0 mm respectively). The monthly total at Kuri Bay was probably higher than observed given that the rainfall gauge overflowed before the observer was able to check the total on the very heavy rainfall day of the 11th, when 388.6 mm was recorded. Kuri Bay recorded 1848.6 mm during summer 2010/11 which was the highest total in WA.

A number of highest daily rainfall records were broken in the third week of December 2010 in the Gascoyne and adjacent parts of neighbouring districts due to a monsoon low moving affecting the area from the 16th to the 18th, with large parts of the west Gascoyne recording over 150 mm and a few sites recording over 300 mm. This rainfall event led to some of the most significant flooding in the Gascoyne River since recording commenced. For further information about this event, please refer to the December WA Monthly Weather Review.

Tropical Cyclone Bianca brought heavy rainfall to the Pilbara coast late in January 2011. Further heavy rainfall was observed in the Gascoyne and Goldfields on 17 and 18 February as Tropical Cyclone Dianne combined with a cloudband resulting in several sites recording daily falls in excess of 100 mm. TC Carlos, which formed over the Top End of the Northern Territory in mid-February and caused very heavy rainfall in Darwin, tracked across the Kimberley and reformed off the west Kimberley coast and brought heavy rainfall as it moved along the Pilbara coast, passing through Onslow and Exmouth on the 23rd. A tropical low towards the end of February brought further heavy falls to the Kimberley and Pilbara with daily rainfall totals of over 100 mm .

Maximum temperature

Maximum temperatures during summer 2010/11 were above average along the west coast of the SWLD and western Gascoyne, contrasting with below average mean daytime temperatures through the remainder of WA. When averaged across WA as a whole, summer 2010/11 was below average in terms of mean daily maximum temperature mainly due to an active monsoon for much of the period in the north. Mardie in the Pilbara observed its "coolest" summer on record with a mean daily maximum temperature of 35.5 °C, whilst Wyndham in the Kimberley equalled its lowest mean daily maximum temperature. The Lower Southwest, however was above average, and Jurien Bay in the Lower West observed its hottest summer on record.

Very hot conditions were experienced in the southeast of WA during the last few days of January 2011, with many sites observing daily maximum temperatures in the mid-to-high 40s. Forrest in the Eucla recorded 48.4 °C on the 30th, not far below the Forrest and WA January record of 49.8 °C set on 13 January 1979, while Salmon Gums Research Station in the Southeast Coastal broke its highest daily maximum temperature record with 46.3 °C.

Very hot and humid conditions were experienced in western parts of WA in the latter half of February due to persistent hot and humid northeasterly winds, and a reduction in the seabreeze near the coast, as a sequence of tropical cyclones moved westward near the Pilbara coast and decayed off the west coast. Several sites in the Central West and Central Wheat Belt registered three consecutive days with daily maximum temperatures over 40 °C.

Minimum temperature

Mean minimum temperatures during summer 2010/11 were above average in western parts of WA and in the Interior and Eucla. In contrast, much of the Kimberley and eastern Pilbara were below average. When averaged across the state, summer 2010/11 was the 6th hottest in terms of mean minimum temperature, while the Lower Southwest was the hottest since comparable records commenced in 1950, breaking the record set in 1977/78. A number of sites in the southwest of WA broke their highest summer mean daily minimum temperature records with consistently warm overnight conditions experienced throughout much of summer, after the first few weeks of December. A few sites in the Gascoyne, coastal Pilbara and other scattered locations in WA also observed their hottest summer in terms of overnight temperatures.

A very hot night was experienced at Eucla on the 30 January 2011 with a minimum of 30.7 °C, breaking the previous hottest night in 52 years of record of 30.2 °C set on 26 February 2009. This extreme minimum came after Eucla recorded its highest maximum for the month of 47.1 °C on the 29 January 2011, not far below Eucla's record of 47.9 °C on 3 January 1979.

Many sites in western and southern WA experienced continuous warm nights (when the daily minimum temperature is 20 °C or above) in the latter part of February 2011, with several sites, including Perth Metro, experiencing a record run of warm nights. Kalbarri's run of warm nights commencing 16 January and spanning February with the 44 consecutive warm nights easily passing the previous record run of 19 consecutive warm nights set in 1985 (7 to 25 February).

Cape Leeuwin in the Southwest district recorded its highest summer mean daily minimum temperature, the hottest summer in 113 years of record. It was also the hottest summer in 50 years at Cape Leeuwin in terms of daily maximum temperature.

Other phenomena

Severe thunderstorms developed in the Central West during 29 January 2011, forming into an organised squall line and tracking towards the south. The storms caused severe localised damage, particularly in the areas of Wongan Hills, Toodyay, Grass Valley, Goomalling, Northam, Spencers Brook, Clackline, Muresk, York and Beverley.

Severe thunderstorms produced flash flooding in the community of Warburton (Interior) on 10 February and in Nungarin (Central Wheat Belt) on 11 February.

Notable events

• A monsoon low caused very heavy rainfall in the Gascoyne from 16 to 18 December 2010, resulting in significant flooding in the Gascoyne River and around the town of Carnarvon.
• Kuri Bay in the west Kimberley observed 1540.4 mm of rainfall during January 2011, which is the wettest month on record for WA.
• January 2011 was the hottest January on record for WA in terms of overnight temperature.
• February 2011 was the 2nd wettest February and 2nd coolest February (in terms of maximum temperature) on record in WA. The Lower Southwest, however, experienced its 2nd hottest February in terms of minimum temperature.
• Four tropical cyclones formed off the northwest of WA during summer 2010/11, with three of these, Tropical Cyclone Bianca; Tropical Cyclone Dianne; and Tropical Cyclone Carlos, having an affect on the WA coast.
