South Australia in autumn 2013: Near record autumn heat for South Australia
- Several warm spells result in temperatures 1 to 3 °C warmer than average.
- Warmest autumn for the State in 8 years, and third warmest autumn on record.
- Above average rainfall in the north and west, but drier than average in eastern agricultural areas.
- Record hottest autumn day and night time temperatures for several locations including Adelaide.
Rainfall throughout autumn 2013 tended to be above average across the north and west of the state, and below average in the eastern agricultural areas.
Moderate, though patchy, rain events occurred in late April and mid May, but the most significant rainfall event for autumn occurred right at the end of the season as a cut-off low pressure system was able to produce widespread rainfall.
Much of April and May saw little in the way tropical activity to produce widespread rain events for the start of the growing season, which followed a drier than average summer and generally low soil moisture. Western parts of the agricultural areas received some useful rainfall in late April, but many locations in the eastern districts waited until mid to late May for any significant rainfall.
Rainfall totals were variable, generally ranging between 30 mm to 60 mm, with some locations in the northwest receiving in excess of 100 mm. Ernabella had the highest rainfall total in the Pastoral districts recording 113.0 mm, most of that total falling in two rain events on March 28th and May 21st.
Rainfall totals across agricultural areas ranged between 40 to 80 mm, with totals in excess of 100 mm across the Mount Lofty Ranges. The Mallee and the Riverland had lower totals around 20 mm. The wettest location in the agricultural districts was at Crafers in the Mount Lofty Ranges, observing 206.0 mm.
Some sites had their highest total autumn rainfall for at least 20 years.
The wettest single day was at Murrays Lagoon (Bayside) with 97.0 mm on 21 Apr.See a map of rainfall deciles.
South Australia was very much hotter than average during autumn 2013. The season began with several weeks of well above average temperatures, particularly across the north of the state. Temperatures were closer to average in April, though another burst of unusually warm conditions in the first 10 days of May saw temperatures 8 to 10 °C above average across the state.
Averaged across the State as whole, the autumn mean temperature for South Australia (combining daily maximum and minimum temperatures) was 1.7 °C hotter than average, the third warmest autumn on record for the state, after 2005 which was 1.9 °C above the long term average, and 1921. By comparison, autumn 2012 was 0.3 °C cooler than average.
Maximum temperatures were 1 to 2 °C above average across much of the the state throughout the season. Several locations including Robe, Mount Gambier, Streaky bay and Adelaide observed hottest autumn days on record.
Autumn maximum temperatures ranged from 18.5°C at Mount Lofty to 30.4 °C at Marree Comparison in the Far North. The hottest autumn day in was on 27th March when temperatures reached 42.8°C at Moomba Airport. The coldest day was 9.4 °C at Mount Lofty on the 22nd of May.
Some sites had their highest autumn mean daily maximum temperature on record. See a map of maximum temperature anomalies.
Over night minimum temperatures through autumn 2013 across South Australia have been the warmest since 2007. Across the State as a whole, minimum temperatures were 1.5 °C warmer than average. In comparison, autumn 2012 was 0.7 °C cooler than normal. The hottest autumn nights for the state occurred in 1923.
Minimum temperatures averaged for the season ranged from 9.2 °C at Coonawarra in the south-east to 16.6 °C at Neptune Island. The lowest recorded minimum temperature was -3.0°C at Naracoorte on the 20th of April, and the warmest night was 28.5 °C at Oodnadatta Airport on the March 27th.
Some sites had their warmest autumn night (highest daily minimum temperature) on record.Some sites had their highest autumn mean daily minimum temperature on record. Some sites had their highest autumn mean daily minimum temperature for at least 20 years. See a map of minimum temperature anomalies.

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 12 pm on Monday 3 June 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
(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.
