Monday, 1 June 2009 - Seasonal Climate Summary for South Australia - Product code IDCKGC23R0
Despite being near average for rainfall totals, the rain fell mainly in a few events, with much of March and April seeing only minor rainfall from early March until the end of April, with another large event near the end of May.
Totals have been generally slightly below average across much of South Australia this autumn, typically 60 to 80% of average, apart from the Mount Lofty Ranges and adjacent areas, and the far western agricultural areas, and the south-western pastoral areas, which saw rainfall above average.
Areas of above average totals in the west were quite patchy due to the rainfall coming from the combination of several events that were not widespread, but were up to twice the average in some locations!!
Rainfall was generally below average across the eastern and northern pastoral districts, and above average in the southwest. Rainfall totals were very patchy but typically from 30 to 50 mm.
The highest autumn rainfall total was 103.9 mm at Tarcoola (Lake Everard) in the far North, when the average for that location would normally be 43.1 mm.
Rainfall totals were generally a little below average, apart from the Mount Lofty Ranges and adjacent areas through Adelaide and down the Fleurieu Peninsula, and the far western agricultural areas west of Kyancutta, which tended above average.
Rainfall totals were typically 30 to 80 mm across northern and eastern agricultural areas, with totals reaching 100 to 150 mm generally around Adelaide and in the lower southeast, with totals between 200 and 300 mm generally through the Mount Lofty Ranges. The highest total for the state was 346.6 mm at Woodhouse in the Adelaide Hills near Piccadilly, about 160 mm of which fell across 4 consecutive days in late April!!
Generally temperatures were slightly cooler than average, particularly in the western and southern parts of the state, with days particularly being cooler than usual. Both autumn maximum and minimum temperatures were widely within 1°C of average.
The hottest autumn day was 45.2°C recorded at Moomba Airport on the 3rd March. The coldest daily maximum was at Ernabella on the 30th May when 8.4°C was recorded, a new record lowest May maximum temperature for that location!!

This statement has been prepared based on information available at 10 am on Monday 1 June 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
(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.
