Aquacaux is a kitesurf spot near Sainte-Adresse / Le Havre (Seine-Maritime), on the north shore of the Seine estuary. The beach faces north-west and catches the dominant West to North-West winds from the open Channel.

Tidal spot. The proximity of the Le Havre port means very heavy maritime traffic — strictly respect navigation rules and stay well clear of shipping lanes. Good wind exposure on this north-facing stretch of coast at the mouth of the Seine.
