South Australia in June 2018: below average rainfall in many districts

Rainfall totals during June were below average in some Agricultural districts, exacerbating serious to severe rainfall deficiencies in those areas for the year-to-date. It was also drier than average in the Northwest and parts of the Far North Pastoral districts. Daytime temperatures were warmer than average across the State's north, but overnight temperatures were cooler than average in much of eastern South Australia.

Continuing dry in some agricultural districts

  • Rainfall totals for June were below average in the Northwest Pastoral district, parts of the Far North, and across the central Agricultural districts
  • For South Australia as a whole, June rainfall was 39% below average
  • The below average rainfall in central and eastern Agricultural districts contributed to the ongoing serious to severe rainfall deficiencies in those areas since the start of the year
  • Yardea and Arkaroola had their lowest total June rainfall for at least 50 years

Cool nights in the east

  • Daytime temperatures were warmer than average across the State's north, but otherwise were close to average in most districts
  • The mean maximum temperature for South Australia as a whole was 0.38 °C warmer than average, continuing a run of 14 consecutive months of above average daytime temperatures for the State; April 2017 was the most recent month with a below average mean maximum temperature for South Australia
  • Overnight temperatures were cooler than average in much of the State's east and in the far northwest, including very much cooler than average nights in the Northeast
  • On the 26th and 27th, overnight temperatures were up to 8 °C cooler than average in some parts of the State
  • The mean minimum temperature for South Australia as a whole was 0.70 °C cooler than average
  • This was the second consecutive month of below average overnight temperatures, which ended a sequence of ten months of above average minimum temperatures from July 2017
  • On the 10th, Ernabella (Pukatja) had its highest June temperature on record
  • Later in the month, several sites with less than 30 years of record set cold temperature records, including Minnipa having its coldest June day on record, and both Moomba Airport and Kuitpo Forest Reserve having their lowest June temperature on record

Strong winds at times

  • High pressure systems over or close to the State brought clear skies and light winds to South Australia for much of the month
  • However, cold fronts crossed the State several times during June, bringing rain and severe winds
  • The strongest wind gust recorded for the month was 117 km/h at Neptune Island on the afternoon of the 11th

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 2 July 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.
