South Australia in June 2020: dry, with cold nights

Rainfall in June was below to very much below average across most of South Australia, making it the State's driest June since 2007.

Driest June since 2007

  • Rainfall in June was below to very much below average across most of South Australia
  • Total rainfall was 65% below average, the State's driest June since 2007
  • The northern Pastoral districts received little or no rain for the month
  • Adelaide was one of the few areas of the State that had a wetter than average month
  • The month began with severe winds and rain across Agricultural districts in the wake of a cold front on the 1st, with several more cold fronts during the month bringing average rainfall to some southern areas
  • Year-to-date rainfall totals have been close to average in most areas of the State, but above average around Adelaide and parts of the southeast, and below average in some parts of the northern Pastoral districts

Warm days in the north, cold nights in the east

  • Daytime temperatures were generally warmer than average in the north and west of the State
  • The mean maximum temperature was 1.15 °C warmer than average, the highest in June since 2017
  • Nullarbor had its highest June mean daily maximum temperature on record
  • Night-time temperatures were below to very much below average in central and eastern areas of the State
  • The mean minimum temperature was 1.18 °C cooler than average for South Australia as a whole, which, despite several years of cooler than average June nights, was the lowest since June 2017
  • On the 10th, Parafield Airport had its lowest June temperature on record during a run of four consecutive nights when temperatures dropped below zero
  • Year-to-date mean maximum and mean minimum temperatures have both been cooler than average in some central and eastern areas, but warmer than average in parts of the State's north and west

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 Wednesday 1 July 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.
