Dive Site Overview
Storebælt og Halskov Rev's connection to the Great Belt Bridge defines its diving geography, presenting two distinct experiences. On the Korsør side, divers can approach the bridge piers or explore the bay, where strong currents are a notable feature.
Shore dives here typically reach a maximum depth of 7 meters (23 ft) if staying within 50 meters (164 ft) of the coast. For those seeking deeper exploration, a boat is required to venture further out where depths can extend down to 30 meters (100 ft). This deeper zone is characterized by powerful currents, demanding careful planning and execution.
Conversely, the old ferry harbor at Knudshoved near Nyborg presents a tranquil environment. This area provides a safe and calm diving experience, free from significant waves, currents, or boat traffic, making it suitable for all experience levels.
Here, divers can explore breakwaters, a vibrant seabed, and the intriguing wreck of a work vessel involved in the bridge's construction, reaching a maximum depth of 8 meters (26 ft). Both sites offer beach access, though conditions between them vary considerably.
Best Time to Dive
While diving is considered good year-round at Storebælt og Halskov Rev, specific conditions and comfort levels shift throughout the seasons. Particularly July and August, summer months present the warmest average air temperatures, reaching around 17-18°C (63-64°F), making surface intervals more comfortable. However, July also sees some of the highest average rainfall at 3.9mm, which might affect surface visibility or comfort. During the colder months from mid-September to April, average air temperatures can drop to 1-6°C (34-43°F), and while the dive score remains 'Good', divers should expect lower water temperatures, which are not consistently reported but generally align with cooler air. Wind speeds also tend to be higher in winter, potentially increasing wave action, though dive scores remain stable. Planning dives during periods of lower wind and less rainfall, particularly in late spring and early autumn, can enhance the overall experience.

Dive Experience & Conditions
Underwater conditions at Storebælt og Halskov Rev present a spectrum, from calm shore entries to dynamic drifts. At the Korsør side, divers often enter from the beach near Halskovodde. Here, currents can be pronounced, particularly on the west side, necessitating a strategy of swimming against the current at the start of the dive. This approach conserves energy and air for the return journey, allowing divers to drift back with the flow. Recreational depth limits for shore dives are around 7 meters (23 ft), but the site offers much deeper opportunities with boat support. Water temperatures vary depending on conditions, as specific data is limited, suggesting robust thermal protection is advisable. In the sheltered Nyborg ferry harbor, divers encounter consistently calm conditions, ideal for exploring the bottom or the work vessel wreck. Visibility varies depending on plankton blooms and recent weather patterns.
Dive Difficulty & Safety Guidelines
Navigating the varied currents at Storebælt og Halskov Rev requires careful attention to safety. Strong currents, particularly near the bridge on the Korsør side, demand that divers understand the flow and plan their dives accordingly, often by swimming against the current initially. Due to potential boat traffic in the Great Belt, carrying a surface marker buoy (SMB) is strongly recommended for all dives to ensure visibility to passing vessels. Divers should always establish a clear navigation plan, such as maintaining a course towards land or following specific patterns, and identify a clear start marker. If disorientation occurs, surfacing with an SMB can help re-establish bearings. From mid-September to April, carrying a primary dive light and a backup light is essential due to reduced ambient light. Always monitor weather conditions using apps like Fcoo or DMI before diving.
