South Australia in November 2017: A wetter than average month with warm nights

November 2017 was wetter than average across much of South Australia, resulting in the seventh-wettest November on record. Maximum temperatures were close to average, while minimum temperatures were much warmer than average and the eighth-warmest on record.

Seventh-wettest November on record

  • Ranfall totals were above average across large areas of South Australia in November 2017, particularly in the Northwest Pastoral district, southeastern parts of the State, and in parts of the Eyre Peninsula
  • Parts of the West Coast around Ceduna and areas around Gulf St Vincent saw below to very much below average rainfall
  • For South Australia as a whole, it was the seventh wettest November on record, and wettest since 2009
  • Several stations recorded their highest total November rainfall on record
  • A band of rain and isolated thunderstorms moved across central districts during the 15th, giving several sites their highest November daily rainfall on record in the 24 hours to 9am on the 16th
  • A slow moving low pressure system over western Eyre Peninsula and a broad trough over central districts generated scattered showers and thunderstorms throughout central and eastern districts on the 22nd and 23rd. Isolated severe thunderstorms were observed over eastern districts with reports of flash flooding in the Barossa Valley. Several sites on the Eyre Peninsula observed their highest November daily rainfall on record in the 24 hours to 9am on the 23rd

Warmer than average temperatures, particularly in the southeast

  • Mean maximum temperatures during November 2017 were warmer than average in southern central and eastern areas, and close to average for the remainder of the State
  • South Australia had its seventh consecutive month of warmer than average mean maximum temperatures, although November 2017 was in the near-average range and 0.91 °C above normal; April is the only month this year so far in which the State's mean maximum temperature was cooler than average
  • Mean minimum temperatures were very much warmer than average throughout the agricultural districts, with several sites in the State's southeast reporting their warmest month on record; overnight temperatures were cooler than average in small parts of the northern Pastoral districts
  • Mean minimum temperatures for South Australia as a whole were 1.65 °C warmer than average during November 2017 and ranked as the eighth-warmest November on record
  • A cold morning on the 4th in southeastern agricultural areas saw several sites record their lowest November temperature on record including Keith (Munkora) with -2.3 °C which was the second-coldest November temperature observed in South Australia only behind the -2.4 °C observed at the same site on 10 November 2013
  • Keith observed both its coldest November temperature (0.5 °C on the 4th) and its warmest November temperature (28 °C on the 29th) in 55 years of record

Strong winds at times

  • On the 22nd, isolated severe thunderstorms were observed over eastern districts, with a wind gust to 82 km/h observed at Murray Bridge
  • A slow moving low generated severe wind gusts of 102 km/h and 100 km/h during the afternoon of the 22nd at Port Augusta Aero and Oodnadatta Airport respectively
  • Severe thunderstorms moved across South Australia on the 30th with a severe wind gust of 119 km/h reported at Oodnadatta

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 Friday 1 December 2017. 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.
