I'm with Stone from Westin. Here in South Florida, we have had only a few days all winter where there hasn't been a wind of at least 10-12, and often more.
But even if there is only a light breeze, I feel like I'm flying going with it and struggling going against it. It never helps me going one way as much as it hurts me going the other. I've notice from my HR monitor that I am working harder with the wind behind me, probably because it is just more fun. When it is in my face, I feel like I'm working harder, but often I'm not, according to the HR monitor.
So I tell myself it's mostly mental and plug along.
