As spring approaches, should skis be waxed with an outdoor temperature wax above zero?
Yes, when temperatures go up, it is recommended to wax your skis with a wax for positive temperature, because they are softer waxes that slide better on the wet snow.
When air and snow temperature are cold, the crystals are getting abrasive, so the wax should be harder. A soft wax slips badly and wears quickly on cold snows. It is interesting to know that even if the air is warm, the temperature of the snow never exceeds zero degrees Celsius.
