The event of arriving at or seeing land after being at sea or in the air.

Landfall is formed from "land" (from Old English *land*, meaning ground or territory) and "fall" (from Old English *feallan*, meaning to fall or to come down). The term describes the act of reaching or coming down onto land, especially after being at sea.
Think of arriving at 'land' after being at sea, which is what 'landfall' means.
