• Currents: Expect everything from mellow reef cruises to strong flow at reef corners. Stay close to your guide and keep a conservative gas plan.
• Surface signaling: Carry an SMB and know how to deploy it. Busy boat lanes and drift-style dives make it essential.
• Wrecks: Treat penetrations as overhead dives. Do not enter enclosed spaces without training, redundant light, and a clear plan.
• Heat and hydration: Dehydration increases risk. Hydrate aggressively and limit alcohol, especially on multi-day dive schedules.
• Flight planning: Leave appropriate surface intervals before flying and consider adding a buffer day for long-range itineraries.

Egypt has recompression capability in key Red Sea hubs, and the national diving authority publishes directories of medical and hyperbaric facilities. Save local emergency numbers in your phone, and carry your insurance details on the boat. If you are doing remote liveaboard routes, ask the operator how they handle evacuation timelines, onboard oxygen, and medical communications.

• No-touch diving: Maintain buoyancy and avoid contact with coral, sand plumes, and reef edges.
• Wildlife rules: Do not chase, feed, or crowd dolphins and turtles. Stay calm, give space, and let animals choose the interaction.
• Moorings over anchors: Prefer operators that use established moorings at popular sites to prevent anchor damage.
• Reef-safe choices: Use reef-safe sunscreen and minimize single-use plastic on boats.
