wind and rain

.
A blustery, whoosh-windy day today ... which puts me in mind of a Chinese farmer's saying I can never remember exactly and maybe someone else will:

Is it, "One day in ten, wind. One day in five, rain?" or "One day in ten, rain. One day in five, wind?"

I have always meant to track it and find out for myself, but every time I begin, I stall out somewhere in the midst of the research and thus remain ignorant.
