Ålesund's diving is shaped by tidal currents and cold, clear water. Drift dives through tidal straits like Skodjestraumen and Vevangstrommen suit intermediate divers seeking the surge of strong flows, while shore-entry reef sites like Vikaneset offer calmer conditions for beginners. The freshwater lake site at Lyngstolsvatnet adds an unusual wreck and artificial reef to the mix. Cod, Monkfish, Common Sea Star, and Dead Man's Fingers are consistently observed across sites, giving every dive a distinctly northern character.















Monthly water temperature across Ålesund's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperatures stay cold year-round, rising gradually from their lowest point in late winter to their warmest in late summer and early autumn, before dropping back through winter. This seasonal arc means a drysuit is appropriate throughout the year. The best-months data points to summer as the most favoured period, when slightly warmer water and longer daylight improve the overall experience.

Cod, Monkfish, Common Sea Star, and Dead Man's Fingers are observed across the vast majority of sites, making them reliable sightings on almost any dive. Brittle Star and Sea Anemone are nearly as widespread. Less frequent but recorded encounters include Orange-clubbed Nudibranch, Rock Crab, and Soft Coral, while Trout can occasionally be spotted at the freshwater lake site.
Several sites cater well to beginners. Vikaneset is a shore-entry reef dive rated for beginners, and Lyngstolsvatnet is a shallow freshwater wreck site also listed at beginner level. The drift sites at Skodjestraumen and Vevangstrommen involve strong currents and are better suited to intermediate divers comfortable managing tidal flow.
Ålesund offers a varied mix: tidal strait drift dives deliver fast, current-driven passages through channels, while reef sites provide more relaxed exploration of rock structures and their resident marine life. Lyngstolsvatnet stands apart as a freshwater lake with a submerged wreck and artificial reef, offering a notably different environment from the saltwater sites.
Both options exist depending on the site. Vikaneset and Lyngstolsvatnet are shore-entry dives, making them straightforward to access without organising a boat. Vevangstrommen is a boat-only site, while Skodjestraumen can be reached by either method. Operators including Ålesund Dykkersenter AS, Ålesund Sportsdykkerklubb, and Scuba Norway AS can assist with boat access and local guidance.
