Victoria in June 2017: driest on record

Rainfall in Victoria during June was very much below average across almost all of the State, with large areas where rainfall totals were lowest on record. Daytime temperatures were above the long-term average across most of Victoria, while night-time temperatures were below average except in parts of the east and south of the State.

Driest on record June in Victoria

  • With 13.7 mm averaged across Victoria, June rainfall was lowest on record since measurements began in 1900; it was 77% below the long-term mean of 59.4 mm
  • Large areas in the north, west and central Victoria received less than 20% of average rainfall for the month
  • A low pressure trough brought moderate falls to eastern and south-central parts of the State on the 6th and to the eastern Victoria on the 7th, with daily totals generally between 5 and 15 mm; higher daily totals were recorded only at several sites in the far east of the State
  • A cold front which crossed the State on the 29th brought more rainfall to southern parts of Victoria
  • The highest daily rainfall total in the State, 43.6 mm was recorded at Cann River on the 6th and Genoa on the 7th
  • The wettest place in the State was Point Hicks with 84.0 mm during the month
  • Many sites had their lowest total June rainfall on record and lowest total June rainfall for at least 20 years

Mild days and cold nights

  • Victoria's mean maximum temperature was 0.51 °C above the long-term June average
  • In contrast, minimum temperatures were below average across most of the State, although eastern and southern parts were close to average
  • For Victoria as a whole the mean minimum temperature was 1.27 °C below average, the coldest since 2006
  • Several sites had their lowest June mean daily minimum temperature on record
  • Many places in the central-north Victoria (including Echuca Aerodrome, Kyabram, Tatura, Shepparton Airport, Mangalore Airport, Redesdale, Wangaratta Aero and Rutherglen) had a record 30 consecutive days during June with minimum temperature 5 °C or below
  • Mt Hotham recorded both the coldest day during the month, -1.9 °C on the 6th, and the coldest night, -6.6 °C on the 30th

High pressure systems dominate

  • Mean sea level pressure was more than 5 hPa above average for June across much of southern Australia
  • The dominant high pressure systems reduced the number of rain-bearing low pressure systems and cold fronts affecting southern Australia
  • Many sites that measure air pressure across Victoria each day, reported their highest monthly 9am mean sea level pressures on record for June
  • Average wind speeds were much lower than the long-term June average at many sites across Victoria

Notes

The Monthly climate summary, generally published on the first working day of each month, lists the main features of the weather in Victoria 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 July 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.
