Ancient Greeks practiced wind scrying in the sacred grove of Dodona, which was dedicated to Zues. Psellus referred to this technique writing "there is a mode of predicting by means of the air and the leaves of the trees.
The method seemed to involve the hanging of striking wands from branches of sacred oak tress in a way that they struck resounding brass basins when the wind blew. Interpretations were made of these sounds and that of the wind.
The wind gives itself naturally to scrying because it talks the same as you or me. Find a quite place in the bush where there is no noise of cars, music, etc.
A place among the trees is the best. Find a tree and sit under it.
Casually focus your attention on the wind, blocking out all other thoughts. In time the wind will talk to you.
In order for you to scry the wind, you must, for a time, become the wind.
