Monday, 1 March 2010 - Seasonal Climate Summary for South Australia - Product code IDCKGC13R0
Summer 2010 rainfall over South Australia was very variable, even for a summer season. Pastoral districts of South Australia had above average rainfall in December and particularly through February leaving the season as a whole wetter than average in those areas.
Agricultural districts further south remained near average generally through summer, though the northern Eyre Peninsula and the Mount Lofty and southern Flinders ranges tended below average for December and February rainfall leaving those areas with below average rainfall for summer as a whole.
Rainfall totals in the pastoral areas were extremely variable ranging from around 20 to 100mm, with higher localised totals at some locations of over 150mm. Moomba Airport recorded a summer rainfall of 270.4mm, most of this occurring during February, and this is then the third wettest summer at Moomba since records began in 1972. This is also the highest rainfall total in the state for this summer. Wirulla in the western Agricultural district recorded only 11.2mm on 6 days across the whole of this summer as the lowest summer rainfall total this year.
Totals in the agricultural areas were generally between 20 mm and 60 mm with the southeast and the Mount Lofty Ranges locations more consistently around the upper end of that range.Some sites had their lowest total summer rainfall for at least 25 years. See a map of rainfall deciles.
South Australia generally was very much warmer than average for summer 2010 in the south but cooler than average in the north for maximum temperatures under cloudy conditions associated with the above average rainfall in that part of the state. A heatwave event across southern Australia in the first week of January saw southern parts of South Australia with temperatures over 8°C degrees above average for that time of year. Widespread rainfall in the northeast in February saw the end of the season being very much cooler than average in the associated cloudy conditions in that area.
Also, many locations had numbers of hot days (days with maximum temperatures > 35°C ) and very hot days (days with maximum temperatures > 40°C ) about twice the summer average.
Mean maximum temperatures over the pastoral districts of the state were up to 2°C warmer than normal in the southern pastoral districts, but tending up to 1°C cooler than average in the northern pastoral areas, and ranged from 32.4°C at Yunta in the Northeast district to 36.9°C at Marree in the Far North district. The hottest summer day in the pastoral areas was on the 27th January with 45.5°C at Marree.
Mean maximum temperatures in the agricultural districts ranged from 22.6°C at Cape Willoughby on Kangaroo Island to Mount Lofty in the Mount Lofty Ranges to 34.0°C at both Kyancutta and Port Augusta Aerodrome in the Western Agricultural Districts. The highest recorded maximum temperature for this summer in the state was 45.8°C on the 11th January at both Murray Bridge in the Lower Murray Valley, and at Keith in the Upper Southeast. The coolest daily maximum temperature was recorded at Kuitpo Forest in the Mount Lofty Ranges with 15.6°C on the 10th of December.
In the pastoral districts mean monthly overnight minimum temperatures ranged from 15.6°C at Gluepot Reserve in the Northeast district to 23.2°C at Moomba Airport in the Far North district. The lowest recorded minimum temperature in the pastoral areas was 7.4°C recorded at Gluepot Reserve on 9th December 2009. The warmest recorded minimum temperature in the pastoral districts was 31.1°C at Arcaroola on the 21st January 2010.
Over the agricultural districts mean minimum temperatures also were generally up to 1°C above average. They ranged from 10.9°C at Naracoorte Aerodrome in the Lower South East district to 19.0 °C at Port Augusta Aerodrome in the Western Agricultural district.
The lowest recorded minimum temperature for summer was 0.1°C at Loxton on the 4th December 2009, whilst the highest recorded minimum temperature was 32.0°C at Port Pirie on the 11th January 2010.Some sites had their lowest summer temperature on record. Some sites had their warmest summer night (highest daily minimum temperature) on record.

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 1 pm on Monday 1 March 2010. 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.
