![]() ![]() The Pilot’s description of the normal current is based on the time of the high tide at Bodø. The above account of the Saltstraumen is rather different than what The Norwegian Pilot reports. Saltstraumen and the Saltstraumen Bridge with the Børvasstindene mountains in the background When the current turns, there is a period when the strait is navigable. The height difference between the sea level and the fjord inside can be up to 1 m (3 ft 3 in). The current is created when the tide tries to fill Skjerstad Fjord. Before that, the area was different due to post-glacial rebound. Saltstraumen has existed for about two to three thousand years. At this point, one source claims that the tidal current can reach 40 km/h (25 mph). Vortices known as whirlpools or maelstroms up to 10 m (33 ft) in diameter and 5 m (16 ft) in depth are formed when the current is at its strongest. Up to 400 million cubic metres (110 billion US gallons) of seawater forces its way through a 3 km (1.9 mi) long and 150 m (490 ft) wide strait every six hours. Saltstraumen has one of the strongest tidal currents in the world.

The narrow channel connects the outer Saltfjorden to the large Skjerstad Fjord between the islands of Straumøya and Knaplundsøya. It is located about 10 km (6.2 mi) southeast of the town of Bodø. It is located in the municipality of Bodø in Nordland county, Norway. Saltstraumen is a small strait with one of the strongest tidal currents in the world.

They can spin them around, fill them with water, and knock them over. Despite what you might think, though, the vortexes don’t swallow up boats. The whirlpools can be more than 30 feet across and 15 feet deep. That creates powerful currents, as well as big whirlpools. That much water moving that fast causes a lot of turbulence. And there can be a difference of about three feet in the height of the water in the channel and in the fjords. ![]() In the case of Saltstraumen Maelstrom, the current can flow at almost 25 miles per hour. And when the tide rolls out, the process is reversed.įorcing that much water into such a tiny channel is like putting your thumb over the opening of a garden hose. Then it squeezes through the channel into the second fjord. When the tide is coming in, it moves from the Norwegian Sea into the first fjord. And that’s why things get jammed up.Īs the tide rises and falls twice each day, water rushes through the channel - up to a hundred billion gallons. The channel is a couple of miles long, but only about 500 feet wide. It takes place in a channel that separates two bits of land. Saltstraumen Maelstrom is one of the most powerful tidal currents in the world. As the water piles up, it creates powerful currents and some impressive whirlpools. Every six hours or so, there’s a watery traffic jam in a narrow channel that connects two fjords in Norway. ![]()
