The haar (a low mist that rolls in off the sea) was swirling around Arthur's Seat in Edinburgh, Scotland, so I recorded this time-lapse video to show just how mobile it is.

Haar is a sea mist that rolls in along the east coast of Scotland when the land further inland warms up. Sometimes it can last for days near the coast, but if you go inland it disappears within a couple of Km from the coast.
