snow in Victoria
see also:
Introduction
- snow in Victoria is mainly confined to the alpine areas in Winter and a good snow season generally starts early June and lasts until end of September
- snow generally falls when temperatures fall to freezing or below and it rains
- thus most falls occur after a cold front passes an area bringing strong, cold south-southwesterly winds from the Antarctic along with many focal cumulonimbus shower producing cloud formations which are scattered and allow periods of blue sky which further allow night temperatures to fall.
- the intensity of the cold front will determine the altitudes likely to receive snow
- the stronger snow producing fronts are generally associated with 100-110kph wind gusts and spread north-easterly into southern NSW
Alpine winter snow seasons in NSW and Victorian alps
- the main factors affecting snow resort depth of snow in winter are (with average affect on snow depths):
- El Niño event reduces snow depth by 17%
- positive Indian Ocean Dipole (IOD) event reduces snow depth by 15%
- El Niño event PLUS a positive Indian Ocean Dipole (IOD) event reduces snow depth by 23%
- However, this results in increased clear skies at night meaning frosty nights which are good conditions for snowmaking machines
- negative Indian Ocean Dipole (IOD) event INCREASES snow depth by 20%
- La Niña has variable effect as the average 25% increased rain in SE Australia may not fall as snow and so snow depth may only increase by as little as 4%
- a neutral Indian Ocean Dipole (IOD) season with a neutral Pacific Ocean (no El Nino or La Nina) generally gives 8cm better than average snow depths
- the frequency of cold fronts, however these cannot be accurately predicted more than a few weeks ahead
- a negative SAM increases the frequency of cold fronts and also of westerlies which dry out the coastal regions and increase snow in the alps
- climate change which is slowly reducing snow seasons in Australia
Best snow trips from Melbourne
- assumes there is snow on these mountains
- Lake Mountain (2 hrs from Melbourne) for skiing
- Mount Buller (3.5 hrs from Melbourne) for skiing
- Mount Donna Buang (1.75hrs from Melbourne) for toboggans
- Mount Hotham (4.5 hrs from Melbourne via the Hume) for skiing
- Falls Creek (5 hrs from Melbourne) for skiing
- Mount Baw Baw (2.5 hrs from Melbourne) for skiing
- Mount Stirling (3.5 hrs from Melbourne) for snow hiking and camping after a 2-3hr hike
- Dinner Plain (5 hrs from Melbourne via the Hume) - for snow hiking and camping near car; only place with snow you can bring your dog
- Mount Buffalo (4 hrs from Melbourne) for toboggan runs and for snow hiking
- Mt Torbreck great for snow hiking and its free
snow down to 1500m
- these are the common cold fronts in Winter in Victoria and are largely responsible for much of the alpine snow as Victoria's Alps snow fields only rise to 1800-1900m
- Mt Hotham 1862m
- Fall's Creek 1830m
- Mt Buller 1800m
- Mt Baw Baw 1500m
snow down to 1100m
- relatively frequent cold fronts in Winter, extend the snow coverage to other alpine areas
- Lake Mountain snow resort (1350m)
- Mt Donna Buang (1250m)
snow down to 900m
- these are more powerful cold fronts and one can expect several of these each winter from May onwards
- they bring light snow falls to the nearby mountains around Melbourne such as Mount Macedon (980-1000m)
snow down to 600m
- there are much less common and further extend the range of snow to produce snow of Mt Dandenong (elevation 633m) and in the central highlands such as:
- Toolangi Wirrawilla rainforest walk (750m)
- Bullarto (750m)
- Lyonville (740m)
- Firth Park (730m)
- Trentham Falls (710m)
- Hanging Rock (680m)
- perhaps Mt Alexander (640m)
- Mt Macedon pub area (615m)
- Kinglake (600m)
- Blackwood (600m)
- Gordon (600m)
- light snowfall typically falls on Mount Buninyong (740m) and Mount Warrenheip (740m) at least once a year
- Note that these events may bring snow falls to Canberra which is at 580-600m elevation, Orange (940m) and even as far north as Stanthorpe (800m) in Queensland
snow down to 400m
- these are quite rare events and further extend snow coverage to the following towns:
- Daylesford (580m)
- Woodend (560m)
- Macedon township (500m)
- Ballan (500m)
- New Gisborne (450-500m)
- Ballarat (435m-500m)
- Toolangi
- Marysville (400m)
- it is likely that by the afternoon, the snow will have retreated from these regions and only found in those closer to 700m or higher
- examples: 11th August 2019, 1st August 2014, July 2007 with lighter falls in June 2016, Aug 2008, June 2008, Nov 2006
