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.
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.
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.

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 1.1°C 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 temperatures were above average this spring, with temperatures generally up to 1 to 2°C above the average across most of the agricultural areas.

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
(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.
