About Dyrøy Lighthouse

Dyrøy Lighthouse is situated at the northwestern corner of Dyrøy, an island located about 16 kilometers east of Ålesund. The structure is a 6-meter tall square tower made of stone, featuring a lantern and gallery, and is painted white. Its light has a focal height of 4.5 meters and projects a directional beam. The operational light cycles between white, red, and green every 8 seconds, with two flashes in sequence. The site is open to visitors, but the tower itself is closed.

Why it matters: This lighthouse provides specific guidance for vessels navigating the coastal waters east of Ålesund, warning them about the hazards near the northwestern tip of Dyrøy island. Its directional light is particularly useful for local fishing boats and smaller craft in the area's narrow channels.
