South Australia in December 2008
Above average rainfall and temperatures across much of South Australia.

Summary

  • Rainfall in South Australia during December was above average across most of the state, chiefly due to a widespread rain event mid-month.
  • Several locations had record highest December rainfall.
  • Both maximum and minimum temperatures were generally above average.
  • Despite the above average temperatures, two locations had record coldest December overnight daily minimums.

An archive of previous monthly summaries for South Australia is also available, as are summaries for other states and many other climate summaries and diagnostics.

Notes

This statement has been prepared based on information available at 11 am on Friday 2 January 2009. 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.
