After some snowfalls, I was able to make snowballs because the temperature here is not very low. However, it is clearly not easy to obtain a snowman as you may do at home, just starting from a small ball and rolling it on the snow, the ball increasing in size at every turn.
Your personal experience probably tells you that in order to make snowballs or a snowman you need relatively warm and fresh snow. It should ‘sticks’ enough to produce a compact ball that holds even if you throw it away or if you want to assemble several big spheres to make your snowman.
