About This Route
Saltstraumen, located near Bodø in northern Norway, is renowned as the site of the world's strongest tidal current, reaching speeds of 40 km/h during peak flow. This narrow strait in the Norwegian Fjords connects two larger bodies of water, creating a dramatic maelstrom perfect for advanced scuba divers seeking thrilling drift dives. Visibility can reach 20-30 meters at slack tide, revealing colorful anemones, wolf fish, and kelp forests clinging to rocky walls. Popular with PADI technical divers, Saltstraumen demands precise timing around slack tide windows, typically 1-2 hours every six hours. Dive operators like Neptunes Dive Center offer guided trips, but independent divers must check tide charts from the Norwegian Hydrographic Service. Expect water temperatures of 6-10°C (43-50°F) year-round, with summer (June-August) providing the longest daylight and calmest conditions. Follow Leave No Trace principles by avoiding contact with fragile marine life and securing all gear to prevent entanglement in currents.
Safety Considerations
The primary hazard is unpredictable tidal currents that can sweep divers miles from the entry point; always dive with a surface interval plan and buddy system certified in drift diving per PADI standards. Cold water increases air consumption by 25-50%, so monitor your SPG closely and plan conservative gas shares. Nitrogen narcosis risks rise on deeper profiles (20-40m), mandate Nitrox training and proper weighting for dry suits. Boat traffic from fishing vessels is heavy; deploy a delayed surface marker buoy (DSMB) upon ascent, as recommended by the Norwegian Diving Federation. Hypothermia sets in quickly without proper thermal protection, and remote location means evacuation to Bodø Hospital could take hours. Check weather via Yr.no app for sudden squalls, and obtain DAN Europe insurance covering hyperbaric recompression in nearby Bergen or Trondheim chambers.
Essential Gear
Pack a high-quality dry suit like the Ursuit Extreme or Waterproof D1X for insulation, paired with Thinsulate undergarments. Mandatory: Halcyon or Dive Rite DSMB with spool, redundant lights (e.g., Light Monkey Big Blue), 15L steel tanks with DIN valves for extended bottom times, and a shearwater Perdix 2 dive computer set for multi-level profiles. Include a signaling SMB reel, lift bag for deco, and VHF radio in a waterproof case. Brands like Scubapro offer reliable regulators with balanced flows suited to high-current environments.
Emergency Tips
In a current sweep, inflate DSMB immediately to signal boat pickup; ascend at 10m/min while dumping air. For lost buddy, establish neutral buoyancy at 6m and deploy DSMB.
