Rainfall

Rainfall totals were well above average across large parts of South Australia this spring, due to the combination of a La Niña event in the Pacific Ocean and a negative Indian Ocean Dipole (IOD) event in the Indian Ocean. See the ENSO Wrap-up for more information. This resulted in South Australia recording its wettest spring on record. Spring 1975 was the previous wettest spring on record. 1975 was the last time that both a La Niña event and an IOD event of this strength occurred simultaneously.

South Australia had a wet start to spring, with September rainfall totals well above average for many locations. October rainfall was also above average across most parts of the State, apart from the southeast which was close to average. November saw above average rainfall predominantly in the north and east.

Pastoral Districts

Spring rainfall was well above average across the Pastoral districts, with several locations setting new highest total spring rainfall records as well as new highest spring daily rainfall records. Rainfall totals were typically from 50 to 200mm, with some locations recording larger totals in isolated thunderstorm events. Blinman recorded 256.7 mm as the highest spring total in the pastoral districts.

Agricultural Districts

Rainfall totals were above average across most parts, tending close to average in parts of the southeast. Several locations set new highest spring daily rainfall records, with two locations setting new highest total spring rainfall records.14:34 1/12/2010 Rainfall totals were typically 100 to 200mm throughout for the spring season. Several locations recorded in excess of 200mm in various parts South Australia. The highest total for the State was 317.0mm at Parawa (Second Valley Forest AWS).  

Some sites had their highest total spring rainfall on record. Some sites had their highest total spring rainfall for at least 25 years. Some sites had their highest spring daily rainfall on record. See a map of rainfall deciles.

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 10 am on Wednesday 1 December 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.
