Thursday, 1 December 2011 - Monthly Climate Summary for South Australia - Product code IDCKGC23R0
South Australia received nearly twice the amount of the November rainfall average for the State as a whole. This is mostly accounted for by very much above average rainfall across the north and northeast of the State, whereas central coastal locations generally received below average rainfall. Large parts in the west and areas in the southeast received close to average rainfall.
See a map of rainfall deciles.
South Australian average year-to-date total rainfall for 2011 (January to November) is ranked as fourth wettest on record. Last year was slightly wetter over the State for the same 11-month period. The highest January through to November rainfall for the State have all occured during the La Nina years of 2010-11 and 1973-74.
Rainfall totals for November 2011 over the pastoral districts were mostly above average to very much above average, apart from some areas on the western border where totals were mostly near average.
The wettest periods for the pastoral areas was between the 7th and 10th of November and again later in the month between the 21st and 26th. Arkaroola recorded 30.3 mm of rain in the 24 hours to 9am on the 9th. Kalamurina received a record highest daily total for the month of 48.4 mm of rain which occurred on the 22nd. Monthly totals in the pastoral districts generally ranged from about 20 to 50 mm, although some locations in the Far North and Northeast received up to 80 mm. The wettest location overall in the pastoral districts was Manna Hill with 89.8 mm for the month.
Western agricultural districts, and parts of the Upper North district saw mainly average to below average rainfall totals during November. The Murray Mallee, The Upper Murray Valley and the Upper and Lower North districts generally received average to above average rainfall. Below average totals were recorded over Yorke Peninsula and southern parts of the Mount Lofty Ranges, while in other agricultural districts stations generally received near average totals.
Totals were in the range of 20 to 30mm in most locations but tending to higher totals, up to about 60mm, in many locations in the Mount Lofty and Flinders ranges, the southeast of the State, and the Murray Malley and Riverland. The wettest overall for the month in the agricultural districts was Parilla in the Murray Mallee, with 81.6 mm.Some sites had their highest total November rainfall on record. Some sites had their highest total November rainfall for at least 25 years. Some sites had their lowest total November rainfall for at least 25 years. Some sites had their highest November daily rainfall on record.
The mean temperature (the average of the daily maximum and daily minimum temperatures) for South Australia as a whole in November 2011 was 1.0 °C warmer than the long-term November average. By contrast, November 2010 was 1.1°C cooler than average.
The area-averaged mean maximum temperature for South Australia as a whole was 1.0°C above the long-term November average. By contrast November 2010 was 1.9°C cooler than average.
Mean maximum temperatures were up to 2°C above average across most of the south-eastern part of the State, but parts of the far northwest were 1 to 2°C cooler than average. See a map of maximum temperature anomalies. Average daily maximum temperatures ranged from 20.3 °C at Neptune Island to 35.1°C at Marree Comparison in the Northeast pastoral district.
The warmest period for many locations was between the 18th and 19th of November as northwesterly winds were directed over the State ahead of a low pressure trough. The hottest day of the month was recorded at Oodnadatta Airport on the 29th with the maximum temperature reaching 43.4 °C.
The area-averaged mean minimum temperature for South Australia as a whole was 1.1°C above the long-term November average. By contrast, November 2010 was 0.3°C cooler than average.
Mean minimum temperatures were up to 2°C above average across parts of the eastern agricultural, central and western districts, and near average across most of the Yorke and Eyre Peninsulas. Parts of the far northwest of the State were cooler than average for November. See a map of minimum temperature anomalies. Average minimum temperatures across the State ranged from 9.1°C at Keith (Munkora) in the State's Southeast to 19.0 °C at Oodnadatta Airport in the Northeast district.
The coldest nights were between the 1st and 3rd, when winds were generally light as a high pressure system moved across the south of the State. The coldest night was recorded at Keith (Munkora) with a minimum of -0.6 °C on the 1st. Another cold period, under the influence of another high pressure system in the Great Australian Bight, brought minimum temperatures down across a number of locations in the northern pastoral districts from about the 24th through to the 27th.
The warmest nights for many locations were around the 18th and 19th of November which was associated with warm northerly winds being directed over much of the State. Oodnadatta Airport recorded the warmest night of the month on the 19th with 27.8°C.

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 8 am on Thursday 1 December 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
(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.
