South Australia in December 2014: A dry and mild end to the year for most of the State

The month began with generally mild temperatures for both days and nights. Temperatures began to increase, tended warmer than average by the end of the second week ahead a trough of low pressure that crossed South Australia. Temperatures cooled in the wake of the trough before becoming warm to hot again by the end of the third week in a north to north-westerly airstream. In the north of the State, temperatures were very high, peaking at 46.5 °C at Oodnadatta on 10 December, while both day and night temperatures tended cooler throughout the month across the agricultral districts. However, across the state as a whole, both daytime and night time temperatures were warmer than average this December with maximum temperatures 1.19 °C warmer than average and minimum temperatures 0.78 °C above average.

December was also generally dry, with very litte rain being recorded across most areas but particulary dry across western and southeastern agricultral areas. The heaviest rainfall was recorded at the start of the month in the north of the State where locally severe thunderstorms with damaging winds were observed across Pastoral districts. Several locations across the agricultural areas had their lowest total December rainfall for at least 20 years.

  • Below average rainfall in the west and southeast agricultural areas
  • Above average day and night temperatures across Pastoral districts
  • Day and night temperatures tending cooler than average across agricultral districts

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 Tuesday 6 January 2015. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages for individual sites 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 10 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.

The ACORN-SAT dataset is used for temperature area averages.
