Victoria in winter 2017: Below average rainfall, cold nights, mild days

Winter rainfall in Victoria was below average across most of the State, particularly across the central and southeastern districts. Parts of the western districts saw near average rainfall. Cooler nights were common across the State during winter with especially across the north of the State. Maximum temperatures were generally warmer than average for most of the State, tending closer to average in the northeast. Overall, Victoria recorded its driest and coolest winter night time temperatures since 2006

Below average rainfall

  • Winter rainfall was below average across Victoria, owing mostly to June rainfall totals being the lowest on record
  • Overall, it has been Victoria's driest winter since 2006
  • The low rainfall throughout the season results in several locations reporting their driest winter in many years

Mild days, cold nights

Wind and Snow

  • Heaviest snow and reports of snow to low levels occurred in August
  • In early August, blizzard conditions over the alpine region produced heavy snow fall (50 to 100 cm over three days) and reports of snow falling at Trentham and near Ballarat
  • A vigorous westerly flow across Victoria with an embedded cold front saw wind gusts in excess of 120 km/h at exposed coastal locations and elevated regions across the Victorian Alps
  • 40-50cm of snow was reported on 17 August across the Alpine areas, with snow levels dropping to 600-700 metres that produced a light dusting of snow across the Dandenong Ranges
  • Snow to low levels occurred across central Victoria, with up to 5 cm reported across the Grampians and Macedon Ranges on the on 20-21 August, and cold front on the 27 August produced snow flurries to low levels (around 250 to 350 m) in the Dandenong Ranges, at Kilmore and Ballan, and on the Mornington Peninsula at Arthurs Seat

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 10 am on Friday 1 September 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.
