Scuba Diving in Gdańsk (2026)

Visibility is best in winter and spring (up to 20–25 m) rather than summer; plan winter/early-spring trips if clarity is a priority.
Drysuits are essential year-round; summer (July–August) water temperatures of 18–20°C still feel cold for most divers.
The Gulf of Gdańsk offers sheltered, calmer conditions than the open Baltic; if offshore conditions are rough, alternate sites within the Gulf are usually available.
Over 6,000 divers visit Polish Baltic wrecks annually; site operators and dive centers have specialized in wreck-diving logistics.
No dangerous marine life; water is brackish and shallow in many spots, with temperature and conditions varying rapidly based on wind.
Gdansk is well-equipped for scuba training with operators trained to international technical diving standards (GUE, ISSF, PADI, SSI).
The region specializes in wreck diving and cold-water conditions; training courses often emphasize wreck awareness and technical skills.
Best diving season is May to October; visibility and water temperature improve during late summer.
Some operators offer year-round training using inland freshwater quarries and lakes in addition to Baltic Sea sites.
Freediving is available through select operators as a complementary activity to scuba diving.

Access Type: Predominantly boat-based (short day trips) with some shore access; no liveaboard requirement
Marine Life: Cod, flounder, crabs, and encrusting marine organisms attracted to wreck structures; no dangerous animals or fish species.
Unique Hazards: Fishing nets and lines left by anglers on wrecks; frequently-visited wreck sites are regularly cleaned. Always carry a cutting tool. Weather-dependent access; wind can quickly prevent departures even on reserved dates. Winter and ice diving are options for experienced divers.
Diving Character: Cold-water, wreck-focused technical diving with strong historical interest (WWII-era vessels and merchant ships). Not a reef or wall destination; primary appeal is wreck structure, cold-water training, and advanced exploration. The Baltic's low salinity (typically below 7%) requires slightly more weight than freshwater; visibility is variable (5–25 m depending on season and location).
Geography And Logistics: The Gulf of Gdańsk (Zatoka Gdańska) is the primary diving area, protected by the Hel Peninsula. Wreck diving is concentrated around Gdynia and Gdańsk ports. Boats from the Tri-City area (Gdańsk, Gdynia, Sopot) operate specialized dive trips. The Gulf offers calmer conditions than open sea; divers can often switch to alternate sites within the Gulf if open-water conditions are poor.

Best Period: May to October
Visibility Peak: Late autumn through spring (winter until early June offers best visibility of 20–25 m)
Summer Note: Late summer visibility can be good for Baltic standards, but algae bloom at summer start may reduce visibility below 5 m in some areas

Details: Water temperature ranges from approximately 4°C in winter to 18–20°C in peak summer (July–August). Drysuits are standard year-round; wetsuit-only diving requires warmer months.
Temperature Range Celsius: 4
Temperature Range Fahrenheit: 39

Overview: Gdansk has multiple established scuba diving operators offering comprehensive certification courses across various levels and training standards.
Operator Density: At least 3 named dive operators active in Gdansk with full service capabilities including training, retail, and maintenance.
Freediving Crossover: Freediving certification courses are available through Baltic PRO as SSI Freediver program with combined online training, confined water sessions, and open water dives.
Depth Certification Notes: Operators offer training for wreck diving, which is the primary diving specialty in the region due to the Baltic's historic shipwrecks.
