Clement
Definition: mild
This is the root word of “inclement,” which is usually always used to refer to bad weather. So “clement weather” means nice, sunny, and mild conditions.
It comes from “clemen” which is Latin for “mild, placid, or gentle,” and is the same root from which we get “clemency.”
Why I Looked It Up
I had heard “inclement weather” a lot, so I got to wondering if “clement” was a thing. It is, but it still seems to be limited to weather – all of the examples I found referred to the climate of a place.
