I typically commute to work on my bicycle once or twice a week, and have done so for many years. When you ride as hard as I do and as far, even a light wind becomes a big factor. I can tell you that the predominant trend is for the morning wind, if there is any (there usually isn't) to be out of the West and for the afternoon breeze to shift around sooner or later to the South West - that is coming out of the South West. I know that this is almost ALWAYS the case unless there's some kind of "weather" happening.
