South Australia in August 2014: A dry month with cold nights and widespread frost

Minimum temperatures were below average for South Australia during August, with large parts of the State observing the coolest August nights on record. Early in the month, central and eastern parts of the state experienced widespread frost over a five day period with minimum temperatures persistently below 0 °C for many locations. Daytime temperatures, on the other hand, were a little above average in most areas.

Rainfall was very much below average across much of the state as a whole, though tended average to above average for some locations in the northeast Pastoral districts. The heaviest rainfall for most parts of the state occurred at the start of the month and again during mid month. On the 1st, a deep low pressure system extended a trough over South Australia which brought cold and unstable air to southern Agricultural areas and produced scattered showers and isolated thunderstorms. It then remained relatively dry for most parts of the state up until the 14th when an upper level cold airmass and associated surface trough brought heavy rain mainly to the Flinders and southern Pastoral districts today with some lighter rain extending further south to adjacent districts during the 15th.

  • Cold nights see record low minimum temperatures across central districts
  • A dry finish to winter for agricultural districts
  • Near average daytime temperatures

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.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 9 am on Monday 1 September 2014. 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.
