In agreement with the author when he says ''Dark, rain and cold, makes it harder.''

I think a seasonal schedule would be best (something like 5am in summers transitioning to 7am in winters), but that's hard to do with our clock-dominated world. And certainly it depends on one's local climate.

I agree, but with more emphasis on the affects of one's local climate. I also think a schedule timed with the local sunrise has very much helped me be productive in my current location (florida). Unfortunately in my hometown of seattle, I find my mood too affected by the seasons. In the winter the sun rises at about 900am, and is set by about 5pm. Combined with constant overcast, it never really feels like the sun rises, and it makes it very hard for me to feel productive/happy.

I have the same issue with living in Vancouver. It might be worse having come from Calgary, Alberta. Generally, in the prairies, the winters are bright and sunny. It's even nice further north around Edmonton where they get more significant snow, because the snow reflects a lot of the sunlight. By contrast, the Pacific Northwest is full of rain and overcast skies. Seasonal Affective Disorder is a term everyone here is familiar with. Most people seem to think snow is the big issue to face in the winter. For me, snow is no problem. Overcast and rainy skies 90%+ of the time is a big issue to consider, however.

same thing here - I live a bit North of Atlanta, and work at home most of the time. When I do go into the office, I have a lot of flexibility to determine my hours. I find that I get up much earlier in the Summer, and much later in the Winter.

I deal with datacenters around the world, so my work schedule is not a rigid 9 to 5 (or 8 to 6), so doing this doesn't seem to cause any problems at work. Especially when I have early AM concalls (EU), and late afternoon calls (AN/NZ).

Yeah, I can tell you that this year in ND driving anywhere early am might not be the best idea. The weather has been particularly bad and the snow plows are not really done before 7am.

I want to do this. Currently not possible due to the fact that I have to drive my wife to school on the way to work but we are moving soon to were we can take public transport.

Winter kills my internal clock, I feel so much better when I wake after the sun is up than right before it. But around where I live currently, that's rather late.
