South Australia in October 2018: warmer than average temperatures, dry in the east

October rainfall for South Australia as a whole was below average, but heavy rain during the last week of the month brought above average totals to the State's west. Both daytime and night time temperatures were above average across most of the State.

Wet in the west, dry in the east

  • October rainfall for South Australia as a whole was 17% below average
  • A significant rain event in the last week of the month brought daily totals in excess of 20 mm to western areas of the State
  • The rain towards the end of the month resulted in some western areas of the State being very much wetter than average, but eastern Agricultural districts finished the month drier than average
  • Little rain fell in the Northeast Pastoral district, where Moomba Airport had no recorded rainfall for the month
  • Uraidla in the Adelaide Hills had the State's highest monthly total of 67.4 mm, but it was still below its October average
  • Two rain events in the first half of the month saw Coffin Bay and Naracoorte have their highest October daily rainfall on record

Warmer than average daytime and night time temperatures

  • Daytime temperatures were above average in most areas of the State, including a large area of very much above average in the Northeast Pastoral district
  • The mean maximum temperature for the State as a whole was 2.11 °C warmer than average, the highest in October since 2015
  • Night time temperatures were warmer than average across most of South Australia, including large areas of very much above average in northern and western parts
  • Minimum temperatures were close to average in the State's far southeast
  • The mean minimum temperature for South Australia as a whole was 1.91 °C warmer than average, the third-highest for October on record and highest since 2015
  • For overall mean temperature, it was South Australia's sixth-warmest October on record

Strong winds at times

  • On the 15th, severe winds and storms resulted in fallen trees and power outages to more than 35000 homes in Adelaide. Mount Crawford recorded a maximum wind gust of 107 km/h in the early hours of the morning and many other sites across the State recorded gusts in excess of 80 km/h.
  • Severe winds raised dust in some areas of the State on the 19th. There were dust storms across a broad area of eastern Eyre Peninsula and the dust was visible over Spencer Gulf on satellite images. In the State's north, Oodnadatta Airport recorded a maximum wind gust during the afternoon of 102 km/h and many other sites across the State recorded gusts in excess of 80 km/h.

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 Thursday 1 November 2018. 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.
