When the ocean meets the river
The tidal bore is the result of a powerful encounter between the Atlantic Ocean and the descending waters of the rivers. At every major tide – particularly when the coefficient exceeds 100 – the rising tide rushes into the estuary with such force that it creates a visible, sometimes spectacular wave. This rare phenomenon is more pronounced when the river’s flow is high and the weather conditions are favourable.
The result: an impressive wave speeding up the Gironde, offering spectators a moment of raw nature and shared emotion.
