All ski waxes reduce friction differently on your skis and snowboard bases in different temperatures.
Warm temperature ski wax is softer and adheres easily to the porous bases of your skis and snowboards. Because of this it lasts longer and is not easily worn away. This is good for dealing with wet granular snow in warmer conditions. But this would not be good for dealing with snow in cold and dry conditions.
In colder conditions the snowflakes are not wet or granular they are dry, pointed and jagged like a perfect looking snowflake. These sharp snowflakes would stick to this softer warm wax creating friction from drag and slow you down.
As you ski or ride in warm temperatures the snow melts slightly from the friction of the base of your board sliding across the snow. This creates small amounts of water which creates a suction type friction slowing you down.
Warm temperature wax works by repelling the water much faster and easer than just your bare bases can. This reduces drag and increase their performance.
