South Australia in April 2022: Above average rainfall with warmer days and nights

Rainfall was above average across central and north-east parts with large parts having totals for the month in the highest 10% of historical observations since 1900, but it was drier than average across south-east coastal and adjacent agricultural areas. Daytime temperatures were above average across much of the state, though areas in the far south-west and parts of the east experienced daytime temperatures closer to average. Night-time temperatures were warmer than average across most of the state with large parts of the eastern half of the state having night-time temperatures in the highest 10% of historical observations since 1910.

Above average rainfall for most areas, but below average along the south-east coast

  • Rainfall in April was above average across central, eastern and north-east parts of the of the state with large areas reporting totals for the month in the highest 10% of historical observations since 1900.
  • South-east coastal areas and adjacent agricultural areas including much of the Yorke Peninsula and Kangaroo Island recorded below average rainfall for April.
  • State-wide, April rainfall was 30.1% above average.
  • Much of the rainfall recorded in April was in the last week of the month with widespread heavy rainfall being recorded between the 25th and 27th and some sites recording their highest April daily rainfall on record.
  • The heavy rainfall at the end of the month resulted in large areas reporting three to four times their long-term monthly average rainfall for April and some sites having either their highest total April rainfall on record or highest total April rainfall for at least 20 years.

Warmer days and nights for most of South Australia

  • Daytime temperatures were warmer than average across most of the state, though closer to average across parts of the east and far south-west.
  • Across the state as a whole, the mean maximum temperature was 1.62 °C above average resulting in the warmest April daytime temperature since 2019.
  • Night-time temperatures were also warmer than average for most of South Australia, with much of the eastern half of the state reporting night-time temperatures in the highest 10% of historical observations since 1910.
  • The mean minimum temperature for South Australia as a whole was 1.90 °C above average and were the 8th warmest in the historical observations since 1910 with several locations recording their highest April mean daily minimum temperature on record.
  • Both daytime and night-time temperatures were persistently above average for much of the first half of April that also saw Ernabella (Pukatja) record its highest April daily maximum temperature and its warmest April night (highest daily minimum temperature) on record.

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 11 am on Tuesday 3 May 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.
