October skies always seem to be very black, whereas December skies seem blue. I don;t know if anyone else has observed this, or whether it's just my imagination.
I have some hypotheses, but none of them seem satisfactory.
- Daylight savings ends in late October. So Oct/Nov skies really are darker than Sept. (but that doesn't explain lighter skies in December)
- It is often rainy in autumn, so the roads reflect vehicle and street lights. And there's (sometimes) snow on the ground in December (though not around here in recent memory).
- Moon is typically in a different phase for a given time of night? (Don't know)
