South Australia in autumn 2016: Warm days and nights, with heavy rain throughout

South Australia recorded a wetter and warmer than average autumn in 2016. South Australian had its equal fourth warmest autumn on record. Autumn rainfall was generally well above average across the State resulting from heavy rainfall recorded in early March and late May.

  • Fifth-warmest autumn
  • Third-warmest autumn nights
  • Eighth-warmest autumn days
  • Wettest autumn since 1989

Overall, autumn rainfall for South Australia was above average, owing to particularly heavy rainfall events in March and May. While parts of southern agricultural areas and some coastal areas recorded average to below average rainfall, very much above average rainfall was recorded in northern pastoral areas. A slow moving trough tracked across South Australia in early March, bringing heavy rainfall to central districts, resulting in some locations recording their wettest autumn day on record. Several sites had their highest total autumn rainfall on record. April saw generally below average rainfall across much of the State, but a wetter May resulted in some sites having their highest total autumn rainfall for at least 20 years, with large areas of the pastoral districts recording more than double the long term seasonal average.

South Australia's overall mean temperature for autumn was more than 1.5 °C above the long-term average, coming in equal-fourth highest in 107 years of observations, with some sites having their highest autumn mean temperature on record.

Average maximum temperatures for South Australia were more than 1.4 °C above normal and seventh highest on record. High temperatures occurred early in the autumn period, particularly through March, and some locations observed their highest autumn temperature on record. Warm daytime temperatures persisted through April and May. More information about the autumn warmth can be found in Special Climate Statement 56 - Australia's warmest autumn on record.

Autumn nights across South Australia were notably warmer than average as a whole, with the season starting off with Moomba, in the far northeast pastoral district, observing its warmest autumn night on record. Warmer than average nights persisted throughout much of the season, resulting in several locations recording their warmest autumn mean minimum temperature on record or their warmest autumn nights in more than 20 years. Minimum temperatures were highest on record in areas of the State's northeast and northern pastoral districts and were very much above average for most of the rest of South Australia. Extended periods of heat, and relatively few intrusions of colder air from the south meant that temperatures remained above average for much of the season. Average minimum temperatures for South Australia as a whole were third warmest on record coming in at more than 1.7 °C above average.

Notes

The Seasonal climate summary 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. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 1 pm on Wednesday 1 June 2016. 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.
