South Australia in September 2019: drier than average, warm days, cool nights

Rainfall in September was below average in many areas of South Australia, with only parts of the Eyre Peninsula, around Tarcoola and in the far northeast having a wetter than average month. Daytime temperatures were warmer than average across most of South Australia, but night-time temperatures were cooler than average in the east.

Drier than average

  • Rainfall in September was 51% below average for South Australia, continuing a run of ten consecutive months of below average rainfall for South Australia as a whole
  • Rainfall was above average over much of the Eyre Peninsula, around Tarcoola and in the far northeast, but was near average to below average elsewhere across the State
  • The highest monthly totals were in central and eastern Agricultural districts, particularly on the Eyre Peninsula, in the Adelaide Hills, and Lower South East district
  • A trough and cold front that crossed the State early on the 20th brought 10 to 30 mm of rain to the Eyre Peninsula and gave a few sites their highest September daily rainfall on record
  • It has been South Australia's driest first nine months of the year on record, with rainfall since the start of the year below average across almost all of South Australia and large areas very much drier than average

Warm days, with cool nights in the east

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 Tuesday 1 October 2019. 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.
