What kind of wave is the Mascaret?
It’s not an ocean wave, and it’s not a classic river wave either: the Mascaret is a freshwater tidal wave that travels upstream – and one that every surfer should ride at least once in their life. There are only around 70 places worldwide where this natural phenomenon occurs.
The basic requirement is a river flowing into a sea with a significant tidal range. As the tide comes in, it forces the water back up into the river, creating a wave twice a day that moves against the current. However, it also requires other factors, such as a narrowing of the riverbed that causes the water to build up.
And all of that comes together in western France, along the Dordogne and Garonne. I’m at the Atlantic very often and had already been there twice without catching the wave. Once I was in the wrong spot, another time I simply didn’t paddle fast enough. This time I was well prepared, everything came together – and it was an incredible feeling.
