If the wind blows at the speed of light can light travel through it?

Answer 1

Since you have already postulated the fantasy that the wind is blowing at the speed of light,

you might just as well go ahead and decide whether or not you want light to be able to travel

through it, then wave the same wand and make it so.

There's no evidence that motion of a material medium has any effect on the ability or inability

of light to pass through it, so a first pass at this sorcery produces the speculation that the light

would have no problem.

Answer 2

First light is not a mechanical wave and so its velocity will not be affected by the speed of any material medium.
