Night time temperatures were cooler than average in much of northern Victoria, and warmer than average in East Gippsland.

Below average rainfall

  • Winter rainfall in Victoria was below average across the north and east of the State, with July particularly dry in those areas

  • Combienbar had its lowest total winter rainfall on record and Giffard had its lowest total winter rainfall since 1982

Mild days

  • Daytime temperatures during winter were warmer than average across much of Victoria, apart from the southwest and part of the north, owing mostly to persistent mild days through much of July
  • Night time temperatures were cooler than average in parts of central and northern Victoria; elsewhere they were close to average, while in East Gippsland night time temperatures were generally warmer than average
  • Statewide averaged daytime temperatures during winter were 0.60 °C above average, while night time temperatures were 0.07 °C below average

  • The lowest daytime temperature during winter, −5.4 °C, was recorded at Mount Hotham on 27 August
  • Clear skies and cold, dry air resulted in several very cold mornings across Victoria towards the end of the season, with Mount Hotham recording the State's lowest minimum temperature for winter of −9.8 °C on 29 August
  • Several sites had either their lowest winter mean daily minimum temperature on record or their lowest winter mean daily minimum temperature for at least 20 years
  • On 11 July, Ballarat Aerodrome equalled its coldest winter day (lowest maximum temperature) on record
  • Towards the end of the season on 29 August, Falls Creek had its lowest winter temperature on record
  • Winter temperatures in the Victorian Alps averaged about 1 °C cooler than average, with Mount Hotham and Falls Creek having their lowest winter mean temperature on record and Mount Buller its lowest winter mean temperature since 1990

Strong and gusty winds, snow

  • Strong, gusty and damaging winds occurred on a number of days through the season, particularly during July and August
  • The strongest wind gusts during winter were recorded on the 8th and 20th July, with gusts of 146 km/h reported at Wilsons Promontory Lighthouse on both days
  • Cold outbreaks following the passage of cold fronts brought regular snowfalls to Alpine areas this winter

Notes

The Seasonal 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 September 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.
