The north and east coast of Jersey offers ocean diving across a varied mix of reef, kelp forest, seagrass, and artificial structures. Sites range from sheltered shore entries such as Bouley Bay and St Catherines to the offshore reef system at Les Ecrehous islands, which requires boat access and careful attention to strong currents. Depths across the region are relatively shallow, suiting beginners through to intermediate divers. Water temperatures reach their warmest in late summer and cool to around ten degrees in winter, so a wetsuit is needed year-round. Marine life includes nudibranchs, pipefish species, ballan wrasse, pollack, cat shark, and various crustaceans.
