Tides in our region

Where to see the tidal bore ?

The tidal bore: where to admire this magnificent spectacle ?

The tidal bore is a natural phenomenon that occurs during high tides. It is a sudden rise of the sea due to the rising tide. It is in fact the “first” wave of the rising tide that flows into the mouths of streams or rivers. It is created when the rising tide “obstructs” the course of the river. It is an incredible sight to behold in our territory.
