The Hel Peninsula's dive sites are defined by wrecks and cold, low-visibility conditions that reward patient, experienced divers. The Delfin Wreck and Kanonierka are the standout sites, both accessed by boat. Gray Seal is the signature encounter, with Cod, Herring, and Righteye Flounder regularly observed alongside. Water temperatures swing widely across the year, making thermal protection a serious consideration. Spring marks the peak window for diving conditions.
Monthly water temperature across Hel Peninsula's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperature drops to its coldest in late winter and rises to its warmest in August, creating a dramatic seasonal range. Conditions are most favoured by divers in April and May, before summer brings its warmest water but potentially busier periods. Visibility is variable throughout the year, so divers should plan accordingly and dress for cold water even in the warmer months.

Fin maps 15 sites in Hel Peninsula (15 scuba diving sites).
Observed species include Gray Seal, Cod, Herring, Righteye Flounder, and Common Moon Jellyfish. Gray Seal is considered the signature encounter across the peninsula's sites. Common Moon Jellyfish and Herring appear across the majority of sites recorded in the area.
At least one site, Kanonierka, is rated as suitable for beginners, though it sits at a meaningful depth on the keel. Cold water and variable visibility are consistent factors across the peninsula, so even beginners should be comfortable diving in challenging thermal conditions before visiting.
Most sites, including the Delfin Wreck, are boat-access only. Kanonierka offers both shore and boat entry options. Several local operators serve the area, including Lena Diving Baltic, Dive Land, and Baza Nurkowa Dive Land.
Wrecks are the dominant site type on the Hel Peninsula. Kanonierka is a well-documented shipwreck resting on its keel, and the Delfin Wreck is another key boat-access site. The wreck-focused character of the area makes it particularly suited to divers interested in underwater structures and the marine life that colonises them.
