Arromanches-les-Bains sits on the Normandy coast in the English Channel, and its diving is defined by D-Day history. The Mulberry Harbour concrete caissons lie within a hundred metres of the beach and are accessible from shore, offering a direct encounter with the wartime artificial port structure. The SS Empire Roseberry wreck sits a short boat ride offshore in very shallow water. A third deeper wreck site lies further offshore for intermediate divers prepared for limited visibility and moderate currents. The water is cold year-round, reaching its warmest in late summer. Spiny spider crab, tompot blenny, squat lobster, and dogfish are among the species recorded here.

The Channel stays cold throughout the year and only approaches comfortable wetsuit temperatures in late summer; a drysuit is the practical choice for most of the year. Visibility is best from summer through early autumn, and currents require careful timing at all sites.
