Favonian is an adjective that means ‘related to the west wind’ or ‘mild wind.’
Coming from Roman mythology, our word of the day gets its origin from Favonius (fay VONE ee us), the Roman personification of the west wind. It breezed into English in the late 16th century and came to refer to a gentle gust of wind. Here’s an example:
My daughter’s flute playing has a gentle favonian quality. It hits my ears like a gentle breeze.
