A gulf is a large, deep coastal inlet larger than a bay, while a bay is a broad inlet generally smaller than a gulf.
Key Differences
Gulfs are large, deep coastal inlets that extend far into the land, often surrounded by the mainland on three sides. Bays are broad inlets of the sea where the land curves inward, generally smaller and less enclosed than gulfs.
