In reply to elliot.baker:
Hmmm, I see some cracking sunrises from my house and in an entirely non-scientific way, these are factors that appear in my view from the living room.
A good view to the east. Mine is varied, loch, farmland, some houses and in one part, I can see the sea and the horizon.
Most of the spectacular sunrises I see are in the winter, but that could be because, living so far north, summer sunrises occur while I’m asleep.
Thick cloud cover isn’t good as it just gets lighter grey. No cloud is usually not as spectacular as having some.
Some of the best I’ve seen have been when there was snow on the ground. I don’t know if it’s a contrast thing or if it’s something more weather/pressure related.
