South Australia in August 2017: above average rainfall in most agricultural districts

August rainfall was above average in many agricultural districts, which also helped keep temperatures slightly cooler than average in the southern and eastern agricultural districts. Further north, the pastoral districts were drier than average with warmer than average days and nights, particularly in the State's northwest.

Wetter than average in the south, dry in the north

  • August rainfall was 20% below average for South Australia as a whole
  • Agricultural areas generally recorded average to above average August rainfall
  • Below average rainfall recorded in pastoral districts, particularly in the northwest
  • A series of cold fronts crossed the State during August, bringing windy conditions with periods of rain that resulted in localised minor flooding in the Onkaparinga catchment
  • Several long-term sites had their wettest August on record
  • Many sites had their highest total August rainfall for at least 20 years

Cool in the south, mild in the north

Strong winds at times

  • In the middle of the month, cold fronts and westerly winds brought gale force winds to coastal waters and adjacent land areas
  • Maximum wind gusts in excess of 90 km/h were recorded at many sites across southern South Australia from 15-17 August
  • The strongest recorded wind gust during August was 124 km/h at Neptune Island on both the 6th and 15th

Notes

The Monthly 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 10 am on Friday 1 September 2017. 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.
