South Australia in winter 2009
Record warmest despite near average rainfall.

Summary

  • Winter 2009 has been the warmest for South Australia since area averaged temperature records start in 1950.
  • The longer individual station temperature observations at Marree saw record warmest Winter, ( and August ) temperatures since records began at this location in 1898.
  • Rainfall was generally near average, apart from the far north of that state tending below average, and Eyre and Yorke Peninsula's and Kangaroo Island tending above average.
  • Both Growing season and Year to date rainfall are tracking near average across most of the state, apart from the north-eastern areas which are tending below average.

An archive of previous seasonal summaries for South Australia is also available, as are summaries for other states and many other climate summaries and diagnostics.

Rainfall

Generally near average around the state, apart from tending below average in the central and northern pastoral areas, and tending above average over Eyre Peninsula, central and lower Yorke Peninsula, and Kangaroo Island. The pattern of rainfall through the season was focussed on late June through July, with the start and finish of the season tending below average.

Growing season rainfall (April to October ) across the state is near average so far, with some parts of the Eyre Peninsula, Yorke Peninsula and Kangaroo Island tending above average, and the north and north-east of the state tending below average. Year to date rainfall is generally near average apart from tending below average across pastoral areas in the north of the state, and in the eastern districts.

Pastoral Districts

Rainfall in winter 2009 was generally below average in pastoral areas, particularly across the eastern and northern pastoral districts. Rainfall totals were patchy but typically from 15 to 30 mm, with some locations recording very much larger totals in isolated thunderstorm events. Yardea recorded 148 mm and Hiltaba 127 mm for example, as the highest winter totals in the pastoral areas.

Agricultural Districts

Rainfall totals were generally near average, with the Eyre Peninsula, lower Yorke Peninsula, Kangaroo Island much of the Mount Lofty Ranges tending above average.

Rainfall totals were typically 80 to 150 mm across northern and western agricultural areas, with totals reaching 150 to 300 mm around western Eyre Peninsula, lower Yorke Peninsula and the Southeast, with higher totals of 250 to 350 mm generally on Kangaroo Island the Mount Lofty Ranges and the lower Southeast. The highest total for the state was 546.3 mm in the Adelaide Hills at Piccadilly.

See a map of total rainfall. See a map of rainfall deciles.

Temperature

Widespread above average temperatures were seen this winter, particularly in August, and through central and northern South Australia. Both maximum and minimum temperatures were within 1°C of average in the south but up to 3 to 4°C above average in the north of the state. Winter 2009 is the warmest winter for South Australia as a whole, looking across the area averaged temperature record, which is available back to 1950. There are few stations recording temperature in South Australia prior to that time, though Marree in the pastoral districts has a temperature record back to 1898, and winter 2009, as well as August 2009, are the warmest across that record for that location, giving some indication that the warm conditions this winter may be unusual looking back prior to 1950.

The hottest winter day was 35.3°C recorded at Oodnadatta Airport on the 15th August. The coldest daily maximum was at Mount Crawford on the 14th July when 8.2°C was recorded. The lowest overnight winter minimum temperature recorded was at Yunta Airstrip on the 7th July when −4.7°C was recorded.

Oodnadatta Airport had the warmest winter mean maximum temperature of 22.5°C. The lowest mean maximum winter temperature was 12.2°C at Mount Crawford in the Adelaide Hills.

The warmest nights on average across winter were recorded on Neptune Island with 12.3°C, while the coldest nights on average were recorded at Yongala in the Northeast Pastoral district averaging 4.1°C for the season.

Notes

This statement has been prepared based on information available at 8 am on Thursday 3 September 2009. 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.
