South Australia in November 2012: Spring ends with record heat and continuing dry conditions

  • Prolonged heat in the last week results in the record warmest November night in South Australia at Oodnadatta on the 29th November.
  • Second warmest November days for the state as a whole.
  • Driest November for South Australia since 1996, with rainfall only 50% of average rainfall.

Rainfall

Rainfall across South Australia was below average through November, resulting in the driest November in 16 years. Apart from a few locations across the central and northern Pastoral districts where rainfall was near average, most locations received below average rainfall throughout the month. Most of the rainfall was associated with a cold frontal system in the first week of the month, and with a tropical feature in the last few days of November. The drier than average conditions this month come on the end of a dry spring due to cooler than average waters to the northwest of Australia.

Pastoral Districts

Rainfall totals over the Pastoral districts were widely below average tending to very much below average, typically ranging between 10 to 15 mm, being only about 50% of average. Todmorden in the North West district recorded 43 mm, the highest in the state this month, with most of this occurring on the 6th and 7th of the month.

Agricultural Districts

Rainfall was widely below average to very much below average across the agricultural districts, totals typically ranged between 10 to 15 mm, and only about 50% of average, though some locations in the Mount Lofty Ranges and the Lower South East districts recorded totals in excess of 20 mm. The highest rainfall total for the month in the Agricultural districts was at Robe in the Lower South East district where 36.4 mm was recorded.

Some sites had their lowest total November rainfall for at least 25 years.
See a map of rainfall deciles.

Temperature

The mean temperature (the average of the maximum and minimum temperatures) for South Australia as a whole in November 2012 was 2.5 C above the long-term average, the highest since 2009. By contrast, November 2011 was 1.0 C above average.

A heatwave event occurred in the last week of the month with temperatures in excess of 10 C above average for several days at many locations, and record warmest temperatures at several locations.

Maximum

Maximum temperatures over South Australia were second highest on record for the State as a whole this month, 3.1 C above average. This just exceeded the previous second on record set in November 2009.

Daily maximum temperatures averaged across the month range from 20.2 C at Neptune Island to 38.0 C at Moomba Airport in the North East district. The warmest day for any location was recorded at Marree where temperatures reached 46.0 C on the 29th . Several locations in the north of the State, including Marree, Oodnadatta, Arkaroola and Leigh Creek, had record highest November average maximum temperatures.

Earlier in the month, on the 1st and again on the 10th and 11th cold air masses with cold fronts brought daytime temperatures to well below average for many locations around the State. Mount Lofty recorded the coldest day for any location when its maximum temperature reached 11.3 C on the 1st.

Minimum

Minimum temperatures averaged across South Australia as a whole were well above average this November, the fourth warmest November nights on record. The warmest nights on average for the month were experienced across the central and eastern districts where minimum temperatures were in excess of 2 C warmer than normal. Night time temperatures were closer to average, if still warmer than average, across the Eyre Peninsula and the Southeast of the State.

During the heatwave at months end Oodnadatta Airport recorded a minimum temperature of 32.3 C on the 29th, a new State wide minimum temperature record for November. This location also recorded warmest November nights for the month as a whole averaging 22.0C for the month. Leigh Creek also recorded the warmest November night on record at this site, reaching 29.4 C on the 26th.

The coldest nights for much of the State was through the 11th and 12th although the coldest night for any location around the State was observed at Keith (Munkora) where the temperature fell to -1.7C on the 10th.

Notes

A Monthly 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.

This statement has been prepared based on information available at 8 am on Monday 3 December 2012. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages 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 20 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.
