Tidal Bores

A tidal bore is a natural phenomenon that occurs when a large, incoming tide moves upstream against the current of a river or estuary, creating a sudden, powerful wave that travels against the river’s flow. This wave results from the tide’s water level rising rapidly and pushing into narrower, shallower river channels, causing a noticeable, often dramatic surge. Tidal bores are relatively rare, occurring in specific locations worldwide with particular geographical conditions, and they can often be observed by boat or shore during high tide, offering a distinctive display of the force of ocean and river interactions.
