I found this video clip on You tube. It's of L'Houmeau beach. This is where I live, so I thought you'd like to see it.
The film has been made by someone concerned about the dangers of windsurfing. The beach is steep and tricky if the tide is low. If you happen here because you are planning to come to L'Houmeau for a holiday, don't swim when there is a low tide, there are still some old oyster beds which you could injure yourself on.
