Rainfall

South Australia received 3 times the March average, with March 2011 being the 4th wettest March on record for the state as a whole. This was due in large part to two heavy rainfall events. Tropical moisture ahead of a surface trough produced showers and thunderstorms over eastern parts of the state on the 7th and 8th of March, with heavy falls recorded at several locations. On the 20th and 21st of March, the passage of a trough of low pressure generated scattered showers and isolated thunderstorms over large parts of the state.

Record falls were reported in the southeast in the 24 hours to 9am on the 21st. Record March daily rainfall totals were recorded at 22 locations with these events, see March daily rainfall records. For Mungeranie and Kalamurina this was the wettest day for any time of year. 25 locations also had their wettest March on record as a result, see highest total March rainfall records. Kalamurina had its wettest month for any time of year with 190.4 mm.

South Australia has had its wettest start to the year (January, February and March) on record, receiving about 3 times the average for this period. The previous wettest start to the year was in 1974.

Notes

A Monthly 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 Friday 1 April 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.
