The wind situation in late October will be different from the wind situation during most of the summer touring season. The vast majority of cyclists ride this route during the summer touring season, and so they are familiar with the wind patterns of that season, and that's what you tend to hear about.

I've both lived along this route and ridden it, and it is quite true that there are often (usually) *strong* winds from the north/northwest during the summer season. They often kick up around noon.

I've never ridden it in late October, and wasn't keeping track of the winds when I lived there; but there should be some good information available somewhere online. During some months the wind patterns are very different.

I have ridden both north and south during winds, and those strong headwinds slow you down more than you might imagine. It's one of those things that many people don't quite believe until they've experienced it.
