Tromsø sits above the Arctic Circle, and its dive sites spread across the surrounding fjords and coastal waters of the Norwegian Sea. The area is defined by wreck diving: sites include the Black Watch, Sud America VIII, DS Flint, and the Tirpitz Wreck, ranging from shallow accessible dives to technical penetrations at depth. Water stays cold throughout the year, peaking in late summer and dropping close to freezing in spring, so a drysuit is essential on every dive. Beyond wrecks, the region offers walls, reefs, and kelp forests, with marine life that includes Atlantic wolffish, king crab, harbour seal, nudibranch, lumpfish, and giant jellyfish. Late summer brings the best weather and daylight for diving.
Monthly water temperature across Tromsø's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperature peaks in late summer and falls to around four degrees Celsius through late winter and spring, making drysuit use non-negotiable year-round. Visibility varies considerably by site, from a few metres on the wrecks to clearer water on open-water walls. Late summer offers the most favourable daylight and surface conditions for boat access.
Water temperature around Tromsø ranges from about 4°C in February to 11°C in July, based on satellite sea-temperature data for its dive sites.
With water around 4–11°C, a drysuit works in Tromsø year-round.
