Rainfall
Apart from the southern coastal areas and the lower southeast of South Australia where rainfall tended above average and some locations reported record highest monthly falls, most locations across the State saw below average rainfall to finish winter. The wettest periods this month occurred between the 17th and 24th of the month. On the 17th a deep low pressure system well to the south of the State was responsible for a broad and vigorous northwest to westerly airstream across the southern districts. A cold front embedded in this airstream brought periods of heavy showers and thunderstorms. Isolated showers and thunderstorms continued through to the 24th in the moist westerly airstream that followed the passage of the low pressure system.
Some sites had their highest total August rainfall on record. Some sites had their highest total August rainfall for at least 20 years. Some sites had their lowest total August rainfall on record. Some sites had their lowest total August rainfall for at least 20 years.
Pastoral Districts
Rainfall totals over the pastoral districts were below average. Totals typically ranged between 5 and 10 mm, though several locations in the northern parts of the pastoral districts recorded no rainfall for the month. The wettest overall in the pastoral districts was at Yardea in the Northwest, with 24.4 mm; 12 mm of which was observed in the 24 hours to 9am on the 29th.
Agricultural Districts
Rainfall totals in the agricultural districts were average, tending to above average about coastal parts and in the southeast of the State, though mostly below average across western agricultural districts. Rainfall totals in the agricultural areas generally ranged from 20 to 60 mm in the Western Agricultural and Upper North districts, increasing to 80 to 100 mm about coastal locations and the Mount Lofty Ranges. The wettest location overall in the agricultural districts was at Uraidla in the Mount Lofty ranges with an August rainfall total of 241.6 mm, 38 mm of which was observed on the 22nd.
Temperature
The mean temperature (the average of the maximum and minimum temperatures) for South Australia as a whole in August 2013 was 2.4 °C above the long-term average, the fourth warmest on record and the warmest since 2009.
Some sites had their highest August mean temperature on record. Some sites had their highest August mean temperature for at least 20 years.
Maximum
Mean maximum temperatures over South Australia were above average across the State throughout August, particularly throughout the pastoral districts, where days averaged in excess of 3 °C above normal. Dytime maximum temperatures were the warmest since 2006, and the sixth warmest on record. Southern agricultural regions observed daytime temperatures closer to, yet still above the average.
Average daily maximum temperatures ranged from 11.1 °C at Mount Lofty to 26.3 °C at Oodnadatta Airport in the Far North district.
The warmest periods for many locations occurred through the last week of August as northerly winds were directed across the State ahead of a trough of low pressure. Oodnadatta recorded the hottest day of the month when its maximum temperature reached 34.5 °C on the 28th.
The coldest day of the month for any location in the Adelaide and Hills region was reported at Mount Lofty on the 19th when the maximum reached 6.4 °C.
Some sites had their highest August mean daily maximum temperature for at least 20 years.
Minimum
Minimum temperatures were widely above average across South Australia through August, apart from areas about the Upper North. With a State-wide anomaly of 1.4 °C above average, August 2013 is the warmest since 2009 and the sixth warmest August nights on record. The warmest part of the State with respect to minimum temperatures was across southern agricultural areas and parts of the northern pastoral districts. Some sites had their highest August mean daily minimum temperature on record. Some sites had their highest August mean daily minimum temperature for at least 20 years.
The warmest nights for most of South Australia occurred during the last week of August. Marree Comparison observed the warmest night for any location in the State on the 29th, with a minimum of 20.8 °C. Yongala, in the Upper North, observed the coldest night with a minimum of –3.1 °C on the 15th.
The warmest nights on average were observed at Neptune Island with 12.2 °C, while Yongala observed the coolest nights on average with a monthly average of 4.0 °C.

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 12 pm on Sunday 1 September 2013. 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.
The ACORN-SAT dataset is being used for temperature area averages from December 2012 onwards. The major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, rather than 1950, and hence rankings are calculated using a larger set of years.
