South Australia in April 2024

Rainfall

  • April 2024 was the eighth-driest April on record (since 1900) for South Australia as a whole.
  • For South Australia as a whole, April rainfall was 86% below the 1961–1990 average.
  • Rainfall totals in April were below (lowest 30% of all years since 1900) to very much below (lowest 10% of all years since 1900) average across most of the state.
  • Little or no rain was recorded for the month in most of the state's north.
  • Rainfall totals were within 10 mm of the 1961–1990 average across much of the Northeast Pastoral district, including small, isolated areas with April totals in the highest 30% of all years since 1900 in southern parts of the district.
  • The wettest area of the state was in the Lower South East, with Mount Gambier recording a monthly total of 49.8 mm, though still below the site's April average of 54.1 mm.
  • Rainfall totals for the 3 months since February 2024 have been very much below average across the central and eastern agricultural districts, including some areas of lowest on record for the 3-month period (since 1900).

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.

This statement has been prepared based on information available at 10 am on Wednesday 1 May 2024. 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.
