Rainfall

Spring 2009 rainfall, when averaged across the South Australian agricultural areas as a whole, has been the 25th driest in the area averaged record which goes back to 1900, and was the wettest spring since 2005.

This was made up of generally above average rainfall in September, below average in October and generally well above average November rainfall after a dry first 3 weeks of the month.

Rainfall totals in the Pastoral areas were very variable but generally ranging from 50 to 100mm. Erudina in the North East Pastoral district recorded 154.6mm as the highest reading in the Pastoral districts. Totals in the agricultural areas were generally between 100 to 200mm, with totals widely exceeding 200mm about the Mount Lofty and Flinders Ranges, and several locations exceeding 300mm. Much of the western agricultural districts saw totals in the 50 to 100mm range. The highest rainfall total for this spring, in the state, was 317.6mm at Piccadilly in the Adelaide Hills.

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

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 1 pm on Wednesday 2 December 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.
