The shape of the crystals
Freshly fallen snow often has sharper crystals. Over time, they become rounded by wind, pressure and temperature fluctuations. The shape affects both friction and wear.
The Wax Room - snow and waxing
The temperature does not tell the whole story. Learn to distinguish between fresh snow, fine-grained snow, transformed snow, coarse-grained snow and man-made snow - and understand how the snow conditions affect grip, glide and your choice of ski wax.
Two ski tracks at minus two degrees can behave completely differently. One may consist of dry, freshly fallen snow with sharp crystals. The other may be glossy, hard and transformed after several days of fluctuating temperatures. The same temperature therefore does not automatically mean the same wax.
When choosing ski wax, you need to weigh up temperature, humidity and the shape of the snow crystals. This applies to both glide and grip. You do not need to be able to make a scientific analysis of the snow, but it is valuable to be able to distinguish between new and old snow, fine and coarse snow, as well as dry and wet conditions.
Freshly fallen snow often has sharper crystals. Over time, they become rounded by wind, pressure and temperature fluctuations. The shape affects both friction and wear.
Dry snow and snow with free water require different properties from the wax. Near zero, small changes in weather and track conditions can make a big difference.
Old and transformed snow is often rounder, harder, dirtier and more abrasive than fresh natural snow. Man-made snow can be particularly abrasive.
The classification below is practical rather than meteorological. The boundaries overlap, but the categories help you understand what is happening under the ski and which direction you should be thinking in.
Freshly fallen snow in clearly sub-zero temperatures often has well-preserved, sharp crystals. The skiing can feel slow and squeaky, especially when it is really cold.
When it is snowing close to zero degrees, the crystals retain their original shape, but the snow contains more moisture. These are sensitive conditions where the grip wax can ice up easily.
The snow has started to transform and the crystals have become smaller and rounder, but the conditions are still dry. This is often easy-to-wax and highly appreciated skiing conditions.
Small, slightly rounded grains are combined with high moisture content. The conditions can shift quickly between good hardwax conditions, icing, and a track that starts to require klister.
The snow has been on the ground for a while and has been affected by wind, skiers, and temperature fluctuations. The crystals are more rounded, and the track can be both harder and dirtier.
Older snow near the freezing point often becomes glossy and glazed in the track. This is a typical transitional condition where hardwax can start to lose grip while a klister that is too soft becomes sticky.
Snow that has melted and refrozen consists of large, hard grains. It is abrasive and can quickly wear away a grip layer that is too weak.
In mild weather, there is free water between the large, rounded grains. The water can create suction under the ski, and dirt sticks more easily to the base.
Man-made snow is denser and often more abrasive than natural snow. Freshly made man-made snow in cold conditions can be very sharp, while older man-made snow becomes more like coarse-grained, transformed snow.
You can get a long way with your hands, your eyes and a little knowledge of the last 24 hours of weather.
If you can see distinct, sharp snowflakes, the snow is new. Small round grains indicate fine-grained snow, while large hard grains show that the snow has transformed.
If it falls apart, the snow conditions are dry. If the snow holds together like a snowball, it is moist. If it runs or glistens, there is free water.
A shiny, hard or icy track is often more transformed than the snow next to it. Assess the surface the ski will actually run on, not just the snow at the side.
Has it snowed recently, been a thaw, refrozen, or blown hard? The weather history often explains why the snow looks and behaves the way it does.
The overview is general guidance. The temperature range of the specific product and the manufacturer's recommendation always take priority.
There are many local and everyday expressions for snow. Here are some of the most common that are also useful when assessing ski conditions.
Both are relevant, but always follow the temperature specified by the manufacturer on the product. Some scales are based on air temperature and others on snow temperature. Snow temperature often changes more slowly than air temperature, especially after rapid weather changes.
This is determined mainly by the snow structure, not solely by whether the thermometer shows above-freezing temperatures. Klister becomes relevant when the snow is transformed, coarse-grained, icy, or wet. Moist new snow near zero can still be hardwax conditions.
Cold fresh snow has sharp crystals and very little moisture. Friction is high and the snow can feel dry and slow. A hard glide wax, thorough brushing, and a fine base structure are normally a good starting point.
Man-made snow is often dense, hard, and abrasive. It can therefore wear down both grip wax and glide wax faster than soft natural snow. Durable products and a good base become especially important.
Moist snow crystals can stick to a grip zone that is too soft or too thick and then freeze onto it. Choose a more precise zero-degree wax, apply thinner layers, and test the wax on the snow before building the entire grip zone.
