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
- Daytime temperatures were above average across most of South Australia, with only the South East districts having close to average maximum temperatures for September
- The mean maximum temperature was 2.87 °C above average for South Australia, the equal sixth-highest on record for September and highest since 2013
- On the 19th, strong northerly winds ahead of a cold front accompanied warmer than average temperatures across the State, with some power outages from wind damage and an elevated fire weather risk
- On the 20th, Renmark Aero had its warmest September night on record
- Following the passage of the cold front on the 20th, Tarcoola had its coldest September day on record
- Night-time temperatures were below average across most of eastern South Australia, including an area of very much cooler than average nights in the Lower South East
- Most western areas of the State had warmer than average nights
- The mean minimum temperature was 0.15 °C above average for South Australia
- A number of sites had their lowest September temperature on record
- A few sites had their lowest September mean daily minimum temperature on record or their lowest September mean daily minimum temperature for at least 20 years
- Naracoorte Aerodrome equalled its lowest September mean temperature on record and Mount Gambier Aero had its lowest September mean temperature since 1992
- South Australia's mean maximum temperature for January to September was the second-highest on record, while mean minimum temperatures have also been warmer than average

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
