Victoria in June 2015: Below average rainfall, near average temperatures

In June, average or less than average rainfall was recorded across most of Victoria, with parts of the south and east with very much below average rainfall. State-wide mean maximum and minimum temperatures were close to average, but there were some cold nights.

  • Lowest June rainfall since 2008
  • Near average daytime and overnight temperatures
  • Some cold nights

The winter started with cold and wet conditions in a wake of a strong cold front which brought snowfalls to the Alpine areas of Victoria. However, for most of the month, the State was under the influence of high pressure systems, resulting in mostly dry month and state-wide rainfall totals 30% below the long-term mean. The highest registered total for the month was 166 mm at Mount Wellington, located in the Victorian Alps. The wettest day during the month was the 18th, when several sites in the east of the State had daily rainfall of more than 50 mm.

State-wide mean maximum temperature was slightly below average for June. Most of the western half of Victoria recorded below-average maximum temperatures, while above-average temperatures were recorded in the eastern half. The highest maximum temperature recorded during the month was 21.2 °C at Mildura on the 12th June. The monthly mean minimum temperature was below average in most of the east of the state and above average across the south-west. However, high pressure systems characterised by clear nights and light winds brought some very low minimum temperatures, particularly on 21st June, when many places had their coldest morning in several years. The lowest minimum daily temperature recorded during June was −7.5 °C at Mount Hotham.

Strong winds caused by a passage of a cold front were recorded across Victoria on 8th and 9th June. Many places experienced wind gusts in excess of 80 km/h, with the strongest (122 km/h) recorded at Wilsons Promontory.

Notes

The Monthly climate summary 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. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review.

A climate summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 11 am on Wednesday 1 July 2015. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

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.

The ACORN-SAT dataset is used for temperature area averages.
