South Australia in spring 2011: A warm spring, with above average rainfall in the North.

  • Warmer spring days as South Australian maximum temperatures exceed the long term average by 1 to 2 C.
  • Drier than average spring rainfall for many coastal districts but wetter than average across northern parts of the state.

Rainfall

Averaged across the state as a whole, South Australia received ~30% more rainfall in spring 2011 than the long-term spring average. This comes after a record wettest spring in 2010. While the far Northwest and parts of the far Northeast of the state received well above average rainfall in spring 2011, rainfall totals across much of the rest state were close to average, though tending below average in the southern agricultural areas.

See a map of rainfall deciles.

Spring began with well below average rainfall in September across much of the state. Rainfall was mostly average during October, although areas in the state's west received well above average rainfall. The season finished with well above average November rainfall across northern areas of the state while southern and coastal districts received average to below average November rainfall.

Pastoral Districts

Spring rainfall was average to well above across the pastoral districts. Rainfall totals varied typically between 50 to 100mm, with some locations recording larger totals in isolated thunderstorm events. The highest spring rainfall total in the pastoral districts was at Manna Hill, in the Northeast, which recorded 128.6 mm.

Agricultural Districts

Rainfall totals were average across most parts, though tending to below average through the southern agricultural areas including the Yorke Peninsula, Kangaroo Island, the Mount Lofty Ranges and parts of the Southeast districts. These districts generally received 70-80% of average spring rainfall.

Rainfall totals were typically 80 to 180mm throughout agricultural districts for the spring season. The highest total for the state was 211.3 mm at Piccadilly (Woodhouse) in the Mount Lofty Ranges.

Some sites had their highest spring daily rainfall on record.

Temperature

Temperatures across South Australia were above average to very much above average during spring 2011. The spring daily average temperature for South Australia as a whole was 1.0 C warmer than the long term spring average, in comparison to spring 2010 which was 1.1C cooler than average. The warmest spring for South Australia was recorded in 2006 where temperatures were 2.1 C above the long term average.

Maximum Temperature

Maximum temperatures were above average this spring, with temperatures generally up to 1 to 2C above the average across most of the agricultural areas. Maximum temperatures were slightly cooler than average in the far northwest of the state. See a map of maximum temperature anomalies. Average maximum temperatures ranged from 17.2 C at Mount Lofty to 31.2 C at Moomba Airport in the far Northeast of the state.

The warmest spring daily maximum temperature was 43.4C recorded at Oodnadatta Airport in the far North on the 29th of November. The coldest daily maximum was 7.9 C at Mount Lofty on the 10th of September.

Minimum Temperature

Minimum temperatures were also above the long term average this spring. Large areas of the western agricultural region had temperatures in excess of 1C above the long term spring minimum average. Minimum temperatures were only slightly above average for most other districts. See a map of minimum temperature anomalies. Average minimum temperatures for the whole season ranged from 6.9C at Keith (Munkora) in the Southeast to 15.9 C at Oodnadatta Airport.

The lowest overnight spring minimum temperature recorded was -3.6 C at Yongala on the 7th of September. The highest minimum temperature recorded was 27.8C at Oodnadatta on the 19th of November.

Notes

A Seasonal 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 8 am on Thursday 1 December 2011. 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.
