South Australia in 2009

Warmest year on record for South Australia


  • In 2009 the mean temperature was 1.3C above average for South Australia as a whole, a record since the area averaged state figures begin in 1910. This is the 17th consecutive year that above average temperatures has occurred.


  • Many locations around South Australia recorded record warmest nights in 2009 when averaged across the year as a whole.


  • For Adelaide, 2009 was the equal warmest year with 2007, being 1.3°C above average for mean annual temperature, while several locations mainly inland, had warmest years on record.


  • 2009 saw a very significant late January and early February heatwave event and the first spring heatwave for Adelaide as temperatures as a whole for November exceeded previous November temperature records by very significant margins. Temperatures were also very much above average in mid-August.


  • Rainfall was generally near to slightly below average in 2009, with rainfall across the state as a whole 88% of the average for the year.


  • After low summer rainfall, the remainder of the year tended slightly above average each month, apart from May, August and October. Growing Season (April to October rainfall) was slightly above average for this year, and the wettest since 2000.


  • Temperatures for the decade from 2000 to 2009 averaged +0.9°C for the state as a whole, the warmest decade in the record, and continuing a steady increase in temperatures since the 1970’s. Rainfall across the decade, for South Australia, has been below average across the agricultural areas, particularly in the eastern districts, tending above average in the far west of the state.

Rainfall

2009 began with below average rainfall in January and February across South Australia, with the state missing out on the substantial rain events occurring in north-eastern Australia in response to weak La Nia conditions in the Pacific Ocean. Rainfall returned to slightly above average from March through autumn and into winter and spring, apart from drier periods in May, August and October. These conditions as a whole were the result of a beneficial influence from the southern ocean through winter, and warmer than average waters off north-western Australia through spring, despite the development of an El Nino in the Pacific mid-year.

Across the whole of South Australia, rainfall in 2009 was 88% of the average. The growing season broke for most locations in the agricultural areas by late April, with near average rainfall through until the end of the season, with growing season rainfall generally ending above average, and the wettest since 2000.

Adelaides annual rainfall was 517.2 mm in 118 days, slightly below the average of 550.2 mm. The record lowest annual rainfall for Adelaide is 257.8 mm in 1967. The combined Adelaide rainfall record dates back 170 years to 1839.

The wettest overall station across South Australia was Piccadilly (Woodhouse) with 1252.3mm, followed by 1162mm at Uraidla, both in the Mount Lofty Ranges district, with the driest overall annual rainfall total for 2009 in the state being 61.8mm at Olympic Dam Aerodrome, in the Northwest district, followed by 78mm at Moomba Airport in the Far North district.

The wettest single day rainfall total was of 96.4mm at Ki Ki in the Upper South East district on the 27th November 2009.

Temperature

The mean temperature (the average of daytime maximum temperatures and overnight minimum temperatures) for South Australia for 2009 was +1.3C above the 1961-1990 mean of 19.5C. This makes 2009 the record warmest year for South Australia since state wide records began in 1910, and it is the 17th consecutive year that state-wide mean annual temperature have been above average. The decade from 2000 to 2009 of mean South Australian temperatures has averaged +0.9C above the 1961-1990 mean temperature, reflecting the steady rise in annual temperatures for South Australia since the 1970s.

Many locations across South Australia had record highest mean annual temperatures in 2009, including Loxton, Warooka, Leigh Creek, Arkaroola, Andamooka, Nonning, Elliston and Marree.

Late January and early February saw an exceptional heatwave event across southern Australia which broke many records in South Australia. Adelaide recorded 9 consecutive days with maximum temperatures over 35 C, the second longest run after the March 2008 heatwave event. A Special Climate statement details this event.

Another period of unusually warm temperatures occurred in mid-August when temperatures across much of Australia were 4 to 6 degrees above average, resulting in a record warmest August for South Australia and Australia more generally. A Special Climate Statement details this event here.

November 2009 also saw a prolonged heatwave event over Australia, resulting in many records broken by very substantial margins, and resulting in Adelaides first spring heatwave ever recorded. As well it was the warmest November on record for many locations, and for South Australia as a whole. Another Special Climate Statement details this event here.

Adelaide in 2009 had an annual mean temperature of 18.4C, 1.3C above the normal of 17.1C, and the equal warmest year in the combined record for Adelaide, which goes back to 1887, with 2007 which also averaged 18.4C.

Some sites had their highest mean daily temperature on record.

Significant weather

Tornadoes

Several tornadoes were observed in South Australia during the year; most occurred in country areas and were accompanied by heavy rain, high winds, large hail and damage to property. Most tornadoes were rated as F0 in the Fujita Tornado Intensity Scale.

A small thunderstorm super-cell on the 11th July, spawned a tornado near Noarlunga in the southern suburbs of Adelaide causing damage to houses and cars.

Waterspouts

During the early afternoon of 6th June, a cluster of cumulus clouds spawned a series of waterspouts over Gulf St Vincent which were clearly visible from Yorke Peninsula and Adelaide beaches.

Severe Thunderstorms

During June severe thunderstorms were associated with the passage of strong cold fronts bringing recorded wind gusts to more than 100 km/h during which caused structural damage to country buildings, tipped over a semi-trailer and brought down power poles in the western suburbs of Adelaide.

A major outbreak of severe thunderstorms in South Australia occurred on 21st September. Hailstones, up to 3-4 cm in size and severe winds resulted in a broad swathe of damage across Eyre Peninsula and northern Yorke Peninsula, with several tornadoes causing localised strips of more severe damage on Eyre Peninsula. Severe thunderstorm activity then extended across into the Mid North with more damage occurring and more tornado activity reported.

Severe Winds

On 25th April, the passage of a front resulted in a significant storm surge, which produced coastal flooding on the northern coasts of Gulf St. Vincent and Spencer Gulf. Parts of the Adelaide coast suffered beach and coastal erosion where sea levels combined with heavy surf. The sea level at Outer Harbour peaked at 3.7 m.

A strong front linked to a large, deep low pressure system swept across South Australia on 30th June. Severe winds were experienced with blowing dust accompanied the front in the pastoral areas. Some of the higher wind gusts recorded were 115 km/h at Whyalla (Eastern Eyre Peninsula), 113 km/h at Nuriootpa (Mount Lofty Ranges) and Loxton (Riverland) and 106 km/h at Adelaide Airport.

A vigorous front embedded in a northwest to westerly flow around a deep low in the Southern Ocean generated severe winds across much of southern SA on 24th August. Adelaide and the Mount Lofty Ranges experienced strong to gale force winds with severe squalls between about 4 pm and 9 pm and was one of the worst affected areas. Notable severe squalls include 91 km/h at Cummins (Lower Eyre Peninsula), 98 km/h at Cape Borda (Kangaroo Island), 91 km/h at Kadina (Yorke Peninsula), 106 km/h at Mount Crawford (Mount Lofty Ranges), 104 km/h at Port Pirie, 98 km/h at Snowtown (Mid North) and 93 km/h at Naracoorte (Lower South East).

On the same day as the major outbreak of severe thunderstorms on the 21st September, many locations in the Flinders and Pastoral districts experienced several hours of gale force westerly winds and blowing dust during the afternoon. Winds of 50-70 km/h with gusts to 95-100 km/h occurred at Port Augusta, Tarcoola, Woomera, Coober Pedy, Marree and Yunta. The highest recorded wind gust was 115 km/h at Woomera. Roof and tree damage was reported from Port Augusta and at Quorn (Flinders).

Another strong front and low pressure system swept across the State on 22nd September, leading to another day of gale force west to southwest winds and thick blowing dust for the West Coast, Flinders and Pastoral districts. At Woomera, Coober Pedy and Marree, the wind blew at gale force (60-70 km/h) for about six hours.

A deep low pressure system tracked from south of Kangaroo Island to Bass Strait during 13th October. A front associated with the low moved through the Adelaide area in the early hours, generating squally winds and scattered tree damage in the southern suburbs and Adelaide Hills, with gusts of 90-95 km/h recorded at Cape Borda on Kangaroo Island and at Mount Crawford and Kuitpo in the Mount Lofty Ranges.

A deep low pressure system south of Kangaroo Island tracked northeast and crossed the Lower South East coast late on 28th November with strong to gale force and squally northwest to southwest winds causing scattered, mostly tree related wind damage and power outages across southern SA. Wind gusts of 90-100 km/h were recorded at Snowtown (Mid North), Mount Crawford and Kuitpo (Mount Lofty Ranges) and Cape Willoughby (Kangaroo Island). Winds were briefly gale force at Kadina (Yorke Peninsula).

Fire Weather

Many fire bans were issued throughout the state during the early months of 2009, predominantly during January.

Notes

An 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 12 pm on Monday 4 January 2010. 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.
