I figure this is more science than photography and I'm curious as to how frequent photogenic sunsets are in other parts of the world, so this seemed like the best place for it...
So, I live in Auckland, New Zealand. I'm a bit of a homebody, I like the region I live in and am seldom inclined to travel far from it. When I do go on holiday, I mostly go to the same place, a family holiday home 3 hours drive away in the Coromandel; roughly 150km east south east from Auckland, as the crow flies. I've taken photographs of nice sunsets when away, but I've been rather surprised by the reaction of some overseas friends to my sunset pictures - some of them talk like they've never seen sunsets like that, and others ask if the colours have been manipulated and/or the pictures doctored.
Now, I always just assumed that a nice sunset was an uncommon, but not unheard of thing everywhere in the world. So I began to wonder if I lived in the sun-set capital of the world or if the respondents to my photos just lived under rocks (or in high-rise cities and didn't look up much)
Auckland and the east side of the Coromandel share several features - sea to the north, west and east, mountains to the west and a humid subtropical climate. Is this region some kind of geographical sunset machine?
I got to thinking more on it after a trip away to a part of the country I don't usually visit last week where I was rather disappointed to discover that despite a prime sunset facing location and good weather, 4 nights in a row yielded unspectacular, muted sunsets.
My first question, for those of you in other parts of the world, is, how frequently would you see a vanilla sky or a pastel sunset? Spring and Autumn are the best months for sunsets here, Winter can be a mixed bag. I'd see a good pastel sunset or vanilla sky two or three times a month that I'd photograph if I had a camera on me. Away on holiday I'll see vanilla skies 6 nights out of 7 for a week in Autumn.
I'd come to assume that skies that looked like they were on fire and sweeping pastel hues from horizon to horizon were normal - or is this just a misconception based on my location?
Now, a note on my photography; my camera is a few years old, small, and I just point it at the sky and shoot. The colours I get on the jpg are never as good as I saw with my eye. I get oranges, pinks, magentas and reds, but the contrast with the blue sky never seems as intense as it did with the naked eye.

Now, part 2; yellow glow.
Three times in the last 15 years I've seen something I call 'yellow glow'. I haven't managed to find anything with a google search so I don't know what else to call it. (I'm reasonably certain I didn't hallucinate the whole thing, other Aucklanders I've talked to seem to remember them)
Basically, it's like someone has turned on an intense yellow floodlight. Like you're viewing the whole world through those yellow contrast increasing lenses. Everything stands out, green plants (of which there are a lot in Auckland) turn an electric shade of lime and the whole thing felt like I was walking around in neon lit cartoon.
I've seen it happen to varying degrees, about half an hour before sunset, persisting nearly until sunset, and always when there has been a mid altitude, solid layer of cloud overhead extending towards a clear horizon, with the sun visible between the cloud layer and the ground. My guess was that scattered yellow light normally not seen before sunset was being reflected back down by the cloud layer, but, I've never been able to find anything written about it, so I remain unsure.
Has anyone else ever experienced that kind of phenomena?
