I believe conventional wisdom says that you will run slower when there is wind (assuming that you are running out and back) because the wind will cost you more time when you run against it, than it will decrease time when you run with it.
However, I had an experience this week where there was a very strong wind (I estimate 15mph constant) during my run, blowing in from about 10 o'clock. At first, I though it would kill my time, but then I realized it might have helped it, or at least didn't hurt my time. On the way out, the wind was at 10 o'clock, and I tilted my shoulder slightly to the right so that the wind would have minimal effect. On the way back, the wind was blowing at 4 o'clock, and I tilted my shoulder slightly to the left. It effectively turned my body into a sail.
