South Australia in winter 2020: dry in the south and west, some cold nights

Rainfall for winter was below to very much below average across large areas of the state's south and west. August was wetter than average across much of the north, however June and July were very dry months for most areas of the state. Nights were much cooler than average in the east during winter, but daytime temperatures were closer to average in the east and very much above average in the west.

Drier in the south and west

  • Rainfall totals were generally less than average across South Australia in winter, despite a wetter than average August across the state's north.
  • A low pressure system across the state's north in early August brought rain and isolated thundestorms to the nothern Pastoral districts, but some areas in the Northeast Pastoral district still recorded less than half their winter average rainfall.
  • Rainfall in winter was 32% below average for South Australia as a whole.
  • The wettest sites were in the Adelaide Hills, with 402.8 mm at Piccadilly (Woodhouse) the highest total recorded for the season.
  • The season began with the State Emergency Service receiving more than 150 call-outs as strong winds and heavy rain hit Adelaide on 1 June.

Cold nights in the east, warm days in the west

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 10 am on Tuesday 1 September 2020. 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.
