South Australia in summer 2017-18: very warm with near-average rainfall overall

South Australia had its fourth-warmest summer on record, and warmest since 2005–06. Summer rainfall was slightly above average for South Australia as a whole, but it was much wetter than average in the west and drier than average for most of the eastern half of the State.

Wet in the west, drier in the east

  • Summer rainfall was slightly above average for South Australia as a whole
  • Rainfall totals were very much above average in the State's west, more than three times the summer average in areas west of Nullarbor
  • Summer was drier than average in both the Far North pastoral district and in the southeastern agricultural districts
  • Western districts were wetter than average in each of the summer months
  • The northeast of the State recorded little or no rain during the season
  • Moomba Airport had its lowest total summer rainfall on record and two other sites in the Far North had their lowest total summer rainfall for at least 20 years

Third-warmest summer on record

Notes

The Seasonal climate summary, generally published on the first working day of each month, lists 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. More extensive discussion of significant weather events, along with later information and data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

This statement has been prepared based on information available at 12 pm on Thursday 1 March 2018. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

In some situations, some or all of the rainfall is in the form of hail or snow. In these cases the totals given are for the water equivalent: the depth of liquid water that results from melting any frozen precipitation. There can be significant 'undercatch' of snow in strong winds, meaning the true precipitation can be higher than that reported.

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.

Where temperature area averages are mentioned, they are derived from the ACORN-SAT dataset.
