Vladivostok sits on the Bay of Peter the Great in the Sea of Japan, and its dive sites reflect the unusual mix of temperate and cold Pacific water that flows through the region. Water temperatures drop near freezing in winter and climb to the mid-teens Celsius in late summer, so a drysuit is standard kit for most of the year. The nine sites in our database range from shallow shore dives to boat-access reef slopes reaching forty metres, with skill levels spanning beginner to intermediate. Divers here encounter Steller sea lions, king crab, bobtail squid, gorgonians, and catshark, alongside an artificial reef at Magnitka and reef structures around islands such as Kreyser and Yelena.

Monthly water temperature across Vladivostok's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Temperatures hover near freezing through winter and early spring, rising to the mid-teens in July and August before dropping again sharply through autumn. Summer months offer the warmest conditions and are the most comfortable window for those without drysuit experience, though properly equipped divers visit year-round.
