South Australia in January 2020: rain in the west and some central districts, some cooler than average days

Rainfall in January was below average for South Australia as a whole, but it was a wetter than average month in the west and for some central districts. Both daytime and night-time temperatures were generally close to average, but it was a warmer than average month in the State's north.

Wet in the west and some central districts

  • Rainfall in January was above average in some central and western areas of South Australia
  • Large areas of the Northeast Pastoral district and some southern and eastern districts had less than 40% of their January monthly average rainfall
  • For South Australia as a whole, rainfall for January was 25% below average
  • The highest monthly totals were in the Mount Lofty Ranges east and south of Adelaide, with 73.8 mm at Prospect Hill the wettest location
  • The wettest day for the State as a whole was the 6th, with widespread totals of 10 mm or more as a cloud band crossed the State, but there were areas of raised dust in the northeast of the State on the same day
  • On the 20th, rainfall totals of more than 25 mm were recorded in the Mount Lofty Ranges, and Kuitpo Forest Reserve had its highest January daily rainfall on record
  • A few sites had their highest total January rainfall since the 1970s

Warmer than average, but some cold days

  • Daytime temperatures for January were generally close to average or warmer than average across South Australia, though slightly below average through western inland areas
  • During the first half of the month, very hot days on the 3rd and 9th were offset by cold days on the 4th and 5th
  • On the 4th and 5th, a band of very much below average temperatures behind a low pressure trough extended across the State from the northwest to the southeast, and many sites had their coldest January day on record
  • Temperatures were generally near-average or cooler than average across the Agricultural districts during the second half of January, although the month ended with three days of hot weather across southern districts
  • The mean maximum temperature for South Australia was 1.16 °C above average, but after several very warm years, it was the lowest for January since 2016
  • Night-time temperatures for January were generally near-average or cooler than average in the south, but warmer than average in the State's north
  • On the 17th, a cold morning in the South East saw Padthaway South have its lowest January temperature on record
  • Heatwave conditions at the end of the month saw several sites have their warmest January night on record
  • The mean minimum temperature for South Australia was 0.48 °C above average, the lowest for January since 2015
  • Kimba and Streaky Bay had their lowest January mean daily minimum temperature since 1996

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 9 am on Monday 3 February 2020. 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.
