TLDR: Cold dry winter snow, go Cold. Variable or mixed conditions, go Universal. Wet spring snow, go Warm. When in doubt go colder. Colder wax still glides. Too warm and it won't.
Start with snow temperature
Snow temperature is the decisive factor in wax selection. But most skiers and riders don't carry a snow thermometer, and frankly most of us never will. So we've done the work for you. Our temperature ranges are calculated and adapted from snow temperature to air temperature, measured in the shade, making the selection process as accurate and straightforward as possible.
Measure in shade specifically because direct sunlight heats the thermometer itself, not the air, giving you a false reading.
Air and snow temperature are not always the same. Snow has very low thermal conductivity and responds slowly to changes in air temperature. The difference depends on time of day, elevation, aspect, and sun exposure. South facing slopes in direct afternoon sun can have significantly warmer snow surfaces than the air temperature suggests. Your phone weather app gives you one number. The mountain gives you many. Check the snow itself when you arrive, not just the forecast.
New snow vs old snow
This is the second variable and the one most skiers overlook.
New snow has sharp, pointed crystals. Those edges create more friction and penetrate softer wax more aggressively. If it has snowed recently, consider going one range colder than the air temperature suggests. The harder wax holds up better against sharp crystals and protects your base.
Old or transformed snow has rounded, smoother crystals. It has been skied on, groomed, or gone through freeze-thaw cycles. More forgiving. Use the wax that matches the air temperature directly.
Which wax for which conditions
Arkvy Cold Ski Wax. Dry, abrasive snow in sub-zero conditions. Deep winter piste, groomed runs, and cold backcountry terrain.
Arkvy Universal Ski Wax. The most versatile wax in the range. Built for shifting temperatures and variable snow types. The Cold and Universal ranges overlap. In that window go with Cold for dry hard snow and Universal for more variable or mixed conditions. Works as an everyday wax, travel wax, or base layer.
Arkvy Warm Ski Wax. For wet, high moisture conditions. As snow approaches and passes freezing point, free water enters the snowpack and increases contact area between ski and snow. This creates capillary suction that slows you down. In these conditions hydrophobicity becomes the critical factor, a wax that actively repels free water breaks that suction and keeps glide consistent. Spring laps, late season piste, wet heavy snowpack.
When in doubt, go colder
A wax that is slightly too cold for the conditions will still glide. A wax that is too warm will feel sticky, slow down quickly, and wear off fast. If you are between two ranges or unsure about conditions, go colder. It is always the safer call.
The simple version
Check the air temperature in the shade. Factor in whether the snow is fresh or transformed and whether you are skiing sun exposed or shaded terrain. Match it to your wax range. When in doubt go with Arkvy Universal. It handles more conditions than any single wax and is the most forgiving choice when the mountain surprises you.
