South Australia in August 2022: wet with warm nights in the south

Rainfall in August was generally above average in the southern agricultural districts, including around Adelaide, and in the state's far north-east. However, monthly rainfall totals were near-average to below average over large areas of the central and western pastoral districts. Daytime temperatures were close to average across most of the state, but were above average in some areas, particularly in the Northeast Pastoral district. Night-time temperatures were above to very much above average in eastern agricultural districts, including around Adelaide, and in the far north-east of the state.

Wetter than average in the south

  • Rainfall totals in August were generally above average in the southern agricultural districts and in the far north-east, but were near-average to below average over large areas of the central and western pastoral districts.
  • For South Australia as a whole, rainfall in August was 4% below the 1961–1990 average.
  • Stenhouse Bay and Sevenhill had their highest August daily rainfall on record.
  • Numerous sites had either their highest total August rainfall on record or their highest total August rainfall for at least 20 years.
  • On the 2nd, strong northerly winds were experienced across many parts of South Australia ahead of a cold front and Neptune Island recorded 111 km/h later in the night, the strongest wind gust recorded in South Australia during the month.
  • On the 23rd, in the wake of a cold front, a pool of cold air moved over South Australia, resulting in brief snow flurries observed at Mount Lofty and Mount Remarkable overnight; the first reports of snow in South Australia this year.

Warmer than average nights in the south

  • Daytime temperatures in August were generally close to average across the state, but the mean maximum temperature for the month was above average in some areas, particularly in the Northeast Pastoral district.
  • On the 3rd, maximum temperatures were more than 10 °C above average in the far north-east of the state and Moomba Airport recorded the highest temperature for the month of 32.4 °C.
  • The mean maximum temperature for South Australia as a whole was 0.54 °C above the 1961–1990 average, the coolest since 2019.
  • Night-time temperatures were above to very much above average in eastern agricultural districts, including around Adelaide, and in the far north-east of the state.
  • Nights were cooler than average in some central and eastern areas, particularly in a region extending from around Ceduna in the west, north to Tarcoola and east to around Arkaroola.
  • On the 9th, eastern areas of the state recorded minimum temperatures more than 6 °C below average, with Yunta Airstrip recording the lowest temperature for the month of -2.5 °C.
  • The mean minimum temperature for South Australia as a whole was 0.26 °C above the 1961–1990 average.
  • Several sites had either their highest August mean daily minimum temperature on record or their highest August mean daily minimum temperature for at least 20 years.

Notes

The Monthly climate summary, usually published in the first week of the following 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 9 am on Friday 2 September 2022. 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.

Information about Australian Indigenous seasonal calendars is available at the Indigenous Weather Knowledge website.
