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.

I'm pretty sure that is confusing cause and effect. I suspect that the
explanation is the one others have given about the source of the wind
being relevant to weather. Weather vanes could easily have been built
with no "tailfeathers" and a big arrowhead if the convention had been
the other way.
