Victoria in June 2018: cold nights, close to average rainfall

June rainfall in Victoria was generally close to average across much of the State. Daytime temperatures were warmer than the long-term average in parts of central and southeastern Victoria, while night time temperatures were mostly below average except in the far-east of the State.

Close to average rainfall

  • Averaged across Victoria, rainfall was 11% below the long-term June mean of 59.4 mm
  • Rainfall was generally close to average across much of the State; it was below average in parts of the West Gippsland, Upper North, East Central, and Western Plains districts
  • Cold fronts and associated low pressure troughs brought rainfall to the northwest of Victoria on the 9th, and to the western and central parts of the State on the 12th; daily rainfall totals were generally between 10 and 20 mm, with locally higher falls
  • A series of cold fronts brought more rainfall to the south and east of Victoria and snowfalls to the Alps between the 15th and 18th, as a parent complex low pressure system in the Southern Ocean moved eastwards
  • During this event, many sites saw daily rainfall totals of more than 30 mm, and several sites had their highest June daily rainfall on record on the 18th
  • The highest daily rainfall total in the State, 100.6 mm, was recorded at Mount Baw Baw, also on the 18th

Mild days and cold nights

  • For Victoria as a whole, the mean maximum temperature was 0.22 °C above the long-term June average
  • In contrast, minimum temperatures were below average across most of the State, except in the far-east
  • Victoria's mean minimum temperature was 0.23 °C below the long-term average for June
  • Although daytime temperatures in June were generally mild, there were some cold days during the month; it was particularly cold between the 16th and 18th, as polar air swept across the State following the passage of a cold front
  • The lowest daytime temperature in Victoria during June, -3.6 °C, was recorded at Mount Hotham on the 16th
  • With light winds and clear skies under high pressure systems, there were plenty of cold nights during the month; the lowest night time temperature, -6.6 °C, was recorded at Falls Creek on the 25th

Snow and strong winds

  • Snow fell across the Alpine region, as polar air swept across Victoria following the passage of a cold front and associated low pressure troughs between the 14th and 17th
  • The strongest winds during June were recorded on the 16th, with gusts of 115 km/h reported at Wilsons Promontory Lighthouse

    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 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.
