South Australia in 2011: 5th wettest year on record for South Australia.

    South Australia had its 5th wettest year on record in 2011, with the state-wide area averaged total more than one and a half times the long-term annual average rainfall.

    Rainfall was above average across almost all of the state with much of northern South Australia receiving two to three times its annual average rainfall.

    Rainfall in the first 3 months of the year was record highest for South Australia, and remained above average generally until June when most months after that tended below average.

    Growing Season (April to October) rainfall in 2011 was below average across much of the agricultural districts, apart from Eyre Peninsula.

    Some locations had record highest daily rainfall amounts, mainly in the rainfall events early in 2011, while Tarcoola in the Northwest Pastoral area recorded its wettest years on record in 2011.

    In 2011 the mean temperature for South Australia as a whole was 20.0C. This is 0.5C warmer than the average temperature (using the standard climatological base period of 1961 to 1990).

    For Adelaide, temperatures were warmer than average, with the annual mean maximum temperature 0.5C above average.

    Temperatures for the decade from 2002 to 2011 have been 0.7C above average for South Australia as a whole.

    Despite significant rainfall in 2010 and 2011, rainfall in South Australia over the last decade has been below average across the agricultural areas, particularly in the eastern districts, but tending above average in the far west of the state.

Rainfall

With a near record strength La Nia event in place in the Pacific Ocean, the first 3 months of 2011 were the wettest since records began in 1900 for South Australia as a whole. As the event finished in April, conditions became drier than average up until October. The development of another, much weaker La Nia event in November led to rainfall totals tending to be above average across much of the State through the remainder of the year. See a map of rainfall deciles.

The record wettest start to the year, and subsequent rainfall, resulted in South Australia recording its fifth wettest year on record following 1974, 1973, 2010 and 1992. Averaged across the whole of South Australia, rainfall in 2011 was 157% of the long term annual average. In comparison, 1974 had more than twice the annual average rainfall.

The growing season (April to October) broke for most, but not all, locations in the agricultural areas with significant rainfall towards the end of May, though with generally drier than average conditions through following months. Conditions in the Indian Ocean through late winter and spring contributed to drier than average rainfall through that period. Much of September was very dry, though a rain event late that month proved very beneficial to many areas in the agricultural districts. Overall, growing season rainfall across agricultural districts was below average being the driest since 2008.

Of interest is that many locations across South Australia have rainfall totals in 2011 quite close to what was recorded in 2010, though with very different distributions of rainfall. In 2011 the start of the year was above average for rainfall tending drier towards the end, whereas in 2010, the distribution of the rainfall through the year was the other way around.

The wettest overall station across South Australia in 2011 was Crafers (Mount Lofty) with 1084.4mm, followed by 1034mm at Woodhouse, both in the Mount Lofty Ranges. The wettest single daily rainfall total was observed at Ernabella (Pukatja) in the Far Northwest, where 173.6mm of rain fell on February 7th. A large number of stations had record highest daily rainfall readings in 2011, mainly in the rainfall events in the first three months of the year. Tarcoola in the Northwest Pastoral district had its wettest year on record, totalling 379.8mm.

Adelaide (Kent Town) annual rainfall was 537.8 mm over 119 days, 12.7mm below the annual average of 550.5 mm (this average is calculated over all years of record, from 1978 to 2010). In 2010, Adelaide received 592.6 mm. The record highest annual rainfall for the complete Adelaide record is 883.2 mm in 1992 at the Kent Town site. This is across the combined Adelaide rainfall record (of both Kent Town and West Terrace) dating back to 1839.

Some sites had their highest total rainfall on record.

Some sites had their highest total rainfall for at least 25 years.

Some sites had their highest daily rainfall on record.

Temperature

The mean temperature (the average of daytime maximum temperatures and overnight minimum temperatures) for South Australia for 2011 was 0.5C above the 1961-1990 climatological average of 19.5C. In comparison, 2010 was exactly on average, while 2009 was the warmest year on record with temperatures 1.3C above average.

For the decade from 2002 to 2011, South Australian temperatures have averaged +0.7C above the 1961-1990 mean temperature, reflecting what has generally been a steady rise in annual temperatures for South Australia since the 1970's.

Adelaide (Kent Town) in 2011 had an annual mean temperature of 17.6C, 0.4C above the average of 17.2C, slightly warmer than 2010 with an annual mean temperature of 17.5C.

Maximum

The annual maximum temperature across the State for 2011 was 0.5C above the average of 26.7C. The warmest year on record for maximum temperatures across the state as a whole is 2007 and the coldest was in 1956. Maximum temperatures averaged across the year, were up to 1.0C above average across central and eastern parts of the State, and about 0.5C cooler in the far west. See a map of maximum temperature anomalies.

Both Woomera Aerodrome and Leigh Creek Airport recorded highest daily maximum temperatures on record, respectively reaching 48.1°C and 46.1°C on January 25th as a slow moving trough of low pressure extended from the Northwest of the State. Despite maximum temperatures during January being 2C to 4C above normal in the northern and central parts of the State, the first 3 months of 2011 were generally cooler than average across South Australia, due to cooler conditions associated with widespread record breaking rainfall events. Maximum temperatures across the State were then generally near average, tending to warmer than average from May through to September, coinciding with below average growing season rainfall. The year finished with maximum temperatures being below average across much of northern South Australia from October onwards.

Adelaide's annual maximum temperature for 2011 was 22.7C, which is 0.4C above the long-term average of 22.3C. The warmest year on record at for maximum temperatures in Adelaide was 2007 where the mean maximum temperature was 23.7C.

Moomba Airport in the far Northeast District, was the overall warmest location for 2011, with an average maximum temperature of 29.6C. The coolest annual maximum in the State was 17.6C at Parawa (Second Valley Forest). The hottest day in 2011 of 48.5C was recorded at Roxby Downs (Olympic Dam Aerodrome) on January 25th 2011, with the coldest day recorded being on the 12th of July when Mount Lofty reported 5.8C.

Some sites had their highest temperature on record.

Some sites had their coldest day (lowest maximum temperature) on record.

Minimum

The minimum temperature averaged across the state for 2011 was 0.6C above the long- term of 12.2C. See a map of minimum temperature anomalies. Warmer night-time temperatures are also consistent with historical patterns, with high rainfall years having increased cloud cover resulting in typically warmer than average nights. 2009 was the warmest year on record for minimum temperatures across the state as a whole, being 1.2C above average.

Adelaide had an annual mean minimum temperature of 12.9C, which is 0.7C above the long-term average for the Adelaide (Kent Town) site of 12.2C. The warmest year for overnight temperatures was in 1973 where the mean minimum temperature was 13.5C at West Terrace.

The coldest night recorded in 2011 was -5.5C at Gluepot Reserve on the 22nd of July. The coolest overnight minimum temperatures were recorded at Yongala where the annual average overnight minimum temperature was 7.8C. The warmest minimum temperatures annually were 15.2C at Oodnadatta Airport. The warmest night was on the 28th of January when the overnight minimum was 34.2C at Oodnadatta Airport.

Significant Weather

Severe Weather summary for 2011:

On January 8th a trough which had developed over the State deepened into a low pressure system resulting in heavy rainfall and flooding in the State's east. 19 locations received record highest January daily rainfall totals associated with this system, the highest being 106.2 mm at Taldra in the Upper Murray Valley.

During the first week of February, a trough of low pressure with embedded thunderstorms moved across the State, as the remnants of tropical cyclone Yasi moved across the north of the State. The resulting high moisture levels and atmospheric instability produced heavy rain, thunderstorms and flash flooding across the northwest parts of the State. Ernabella received 174 mm of rainfall in 24 hours on the 6th. Later in the month, a low pressure system over Central districts produced heavy rain resulting in flash flooding in that area.

In early March, the remnants of a tropical low and a trough in the west produced broad areas of heavy rain with severe thunderstorms and flash flooding across the State; significant 24 hour rainfall totals include 134 mm at Kalamurina and 170 mm at Dulkaninna. Severe thunderstorms developed in the north of state on the 18th, deepening to produce heavy rain through to the 20th. Localised flooding was reported at several locations across the Yorke Peninsula.

An intense low pressure system in late May and high astronomical tides resulted in unusually high sea-level in both South Australian Gulfs, with storm surge flooding and some minor damage at several coastal locations.

Significant damage was reported on June 20th and ~10,000 homes were left without power following the passage of a pre-frontal trough and an intense low pressure system. Severe wind gusts were reported across the south of the state at several locations, with suspected tornado activity at Robe. In the first week of July, a low pressure system and trough saw severe winds, hail and thunderstorms across southern parts of the State. Later in July, gale-force winds associated with a low pressure trough brought down trees and power lines about the Adelaide Hills.

Severe winds around a deep low pressure system crossing the State's southeast saw reports of trees down and storm damage at Millicent in the southeast on August 17. On the 18th and 19th of September a strong cold front produced severe winds, while on the 28th, a pre-frontal trough ahead of a significant cold front produced thunderstorm activity and severe winds, with reports of trees down around Port Augusta and in the Mid North. On October 28, a trough moving across the State triggered severe thunderstorms about the North West Pastoral and eastern districts, and a tornado was reported at Winke in the Riverland causing damage to property and vegetation.

On November 8th, severe thunderstorms in the North West Pastoral region intensified into a meso-scale convective system, producing damaging wind gusts and local flash flooding. Severe wind gusts up to 120km/h were recorded at several sites, and power outages occurred with a tornado sighted in the Riverland, and golf ball sized hail reported at Gluepot and Waikerie.

On December 17th and 18th a deepening low pressure system and trough triggered large areas of rain and thunderstorm activity across central and eastern South Australia, with heavy rainfall, strong winds and golf ball sized hail causing damage on Yorke and Eyre Peninsulas, and in the Mid North and Riverland. Gluepot in the North East Pastoral district reported 102mm in 24 hours.

Notes

A Annual Climate Summary is prepared to list the main features of the weather in South 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 9 am on Tuesday 3 January 2012. 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 20 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.
