South Australia in autumn 2015: Cool with average rainfall

Cooler temperatures across most districts, with average to above average rainfall across some central and eastern districts.

  • Both day and night temperatures cooler than average
  • Above average rainfall across some eastern districts
  • Wet April results in above average autumn totals for some locations

Overall, both maximum and minimum temperatures tended below average for autumn. Agricultural areas experienced the coolest days, with daytime temperatures tending 1 to 2 degrees below the long term average while some locations had their coolest autumn days in 20 years.

The South Australian statewide average rainfall during autumn was below the long-term average, owing to a particularly dry March. A widespread rainfall event in the middle of April produced highest April daily rainfall on record for locations across central and eastern districts. May saw a return of mostly dry conditions across large areas of the pastoral districts while southern parts of the state had average rainfall for the end of the season, however a broad rainband that extended across the northern half of the State at the end of May brought totals for the season closer to average.

Notes

A Seasonal Climate Summary is prepared to list 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. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 12 pm on Monday 1 June 2015. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

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.

The ACORN-SAT dataset is used for temperature area averages.
