I live on the plains. It's usually windy. Winds up to 20 mph won't affect my plans. They do affect my ride, though; it's obviously much slower going upwind than down. Over 25 mph and I will try to avoid headwinds as much as possible and while I have ridden with crosswinds of over 30 mph, I don't like it and will generally not ride at all if the weather app on my phone reports 30+.
