Monday, 2 July 2012 - Monthly Climate Summary for South Australia - Product code IDCKGC13R0
South Australia received close to the June rainfall average for the State as a whole, with the agricultural districts receiving rainfall that was up to 30% above average for June. The North-east Pastoral districts generally received above average rainfall, though the remainder of the pastoral districts and the northern agricultural districts saw totals that are below average for June.
Rainfall for the year to the end of June 2012 is above average across much of the State, particularly across the North-east Pastoral district, but tending below average in the far west and the southeast.
For the growing season rainfall (April to October) so far, April to June rainfall has been near average across most of the agricultural districts apart from the northern areas and Murray Mallee, and well above average on some parts of Kangaroo Island and the Lower Eyre and Fleurieu Peninsulas. The pastoral districts have received below average rainfall across this same period.
The North-east Pastoral districts received most of their rainfall early in the month from a rain event extending across Queensland, with most of the remainder of the month without rain. Monthly totals generally ranged from 5 to 15 mm, with higher totals in the northeast. The wettest overall was Yardea in the North-West Pastoral district with 43.0 mm.
The passage of a series of cold fronts in the first and third week of June delivered most of the month's rainfall to agricultural areas of the State with monthly rainfall totals near average, tending above average in areas closer to the coast.
The Upper Murray Valley, Murray Mallee and Upper North districts generally received rainfall totals of 20 to 40 mm. Most remaining areas in the agricultural districts recording totals in the 50 to 100mm range, though much of the Mount Lofty Ranges and parts of Kangaroo Island and lower Eyre Peninsula saw rainfall totals in excess of 100mm, with the highest June total in 2012 for the state being 257.3mm at Myponga on the Fleurieu Peninsula.Some sites had their highest total June rainfall on record. Some sites had their highest total June rainfall for at least 25 years. Some sites had their lowest total June rainfall on record. Some sites had their highest June daily rainfall on record. See a map of rainfall deciles.
The mean temperature (the average of the maximum and minimum temperatures) for South Australia as a whole in June 2012 was 0.6 °C below the long-term average, the coldest June for the State since 2007.
Mean maximum temperatures over South Australia were widely colder than average though generally within 1.0°C of average across the state.
The coldest period was through 21st and 22nd with a strong cold frontal system directing a cold southerly airstream across the State. Mount Lofty recorded the coldest day of the month on the 22nd when its maximum temperature only reached 5.9°C. The warmest period was early in the month and in the northerly air stream ahead of the cold front in the third week of the month though the warmest day recorded was 28.0 °C at Marla on the 13th.
Average daily maximum temperatures over the pastoral districts ranged from 15.6°C at Yunta in the Northeast district to 19.4°C at Oodnadatta Airport in the North East district.
Average daily maximum temperatures across the agricultural areas ranged from 9.4°C at Mount Lofty to 18.2°C at Nullarbor in the Western Agricultural District.
See a map of maximum temperature anomalies.
Mean minimum temperatures were generally within 1°C of average at locations across South Australia when averaged across the whole of June, though most locations tended to be colder than average.
The coldest nights were in the 2nd week of the month in clear skies and light winds from a persistent high pressure system. The minimum temperature at Yunta fell to -6.6°C on the 11th during this period, the coldest night for the month in the State. The warmest nights were early in the month with large parts of the pastoral areas up to 6°C above average on the night of the 1st. The warmest night for the month was 15.7 °C at Neptune Island 2nd.
Over the pastoral districts average minimum temperatures for the month as a whole ranged from 1.9°C at Yunta in the Northeast District to 6.1°C at both Andamooka in the Northwest District, and Moomba in the Northeast district. Over the agricultural areas average overnight minimum temperatures ranged from 2.3°C at Yongala to 12.2°C at Neptune Island.
Some sites had their lowest June temperature on record.

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 9 am on Monday 2 July 2012. 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.
