I suspect that it comes from the days of sailing ships. All of your course
decisions are based on the direction of the wind. Tacking, running,
reaching, etc. are all referred to the current wind direction. I'm not sure
I fully understand why FROM was chosen as the convention, but when you're
sailing, you tend to keep the wind in your face unless you're running.

Why is that?

The convention is probably a result of the way a weather vane works;
the arrowhead points into the wind, so a compass rose placed under it
indicates the direction of the wind's origin.
