About Duncome Bay

This is one of the less dived, yet beautiful cliff surrounded beaches in Norfolk. Once on the beach, you can drop into shallow waters and make your descent down a gradual sandy slope. Here you will find a beautiful sandy bottom, majestic wall, and many boulders to explore. These formations are coral encrusted and rich in marine life.

Dive Site Hazards

  • Unstable Visual Ascents — Relying on wall visuals can destabilise ascents.

  • Gradual Depth Creep — Lack of visual bottom reference can cause unnoticed descent.

  • Unsignalled Downcurrents — Downcurrents can form without visible indicators.

  • Bubble Trapping Under Overhangs — Rock overhangs can trap exhaled bubbles, reducing visibility and causing disorientation.

  • Reflected Surge Patterns — Surge reflecting off rock faces can create irregular and unpredictable water movement.

  • Current Funnel Effect — Narrow gaps between rocks can accelerate water flow unexpectedly.

  • Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

  • Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

  • Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.
