Newhaven West Arm is a shallow harbour-wall shore dive with training appeal.
Newhaven West Arm is a shallow harbour-wall dive on the Sussex coast, used for training and relaxed shore diving when the tide and weather line up. Access is usually via the shingle beach, with boat access also possible from the marina. Expect a simple inshore route, a shallow profile, low-visibility windows, tidal pull, and snag risk from fishing gear around the wall.

Safety Notes
Carry a cutting tool, keep close buddy discipline, and expect snag risk from fishing gear around the wall.

Shingle access can be awkward at low tide, and fishing gear around the wall is a real snag risk.
Legal Notes
Follow local harbour guidance and any posted site notices.
Community notes to help plan your visit.
Scuba Diving
Best as a training or buoyancy dive with a long shallow descent and a simple route to read.
Freediving
Only for experienced freedivers in very calm conditions; the low visibility and tidal pull make it a poor casual freedive site.
Snorkeling
Only worth considering on very calm days. The shallow profile helps, but low visibility and flow limit casual snorkelling.
