Hoar frost refers to the white ice crystals, loosely deposited on the ground or exposed objects, that form on cold clear nights when heat losses into the open skies cause objects to become colder than the surrounding air.

Early morning.

And it's already frosted with a thins coat of icey crystals.
I personally think it's a bit early for that. Hehe. I wish summer had lasted a bit longer..

The word frost is actually the same in Norwegian and English, but a quick google search couldn't give me any good answers as to where the word originated. Just like in English, the word frost is used to indicate temperature bellow freezing point and those little ice crystals on my photos.

Frost is so beautiful ♥
