When it's cold, so cold that your feet make a crunching sound in the snow when walking. But without very much wind or blowing snow. Where the sky is bright and cloudless and all of it is so bright that you need to cover your eyes. Think it's usually described as cold and clear.
Also like those days in summer when the morning is slightly foggy and the sun evaporates the fog and brightens it all up. And those autumn days when you can hear the wind blowing through the trees.
