Funen draws divers with a mix of wrecks and reefs across sheltered straits, all at relatively moderate depths. The scuttled ferry M/F Ærøsund and the motor torpedo boat MTB 1 give wreck enthusiasts compact, accessible targets, while Romsoe Rev and Svendborg Sundbroen suit those building experience on natural and artificial reef structure. Water stays cold for much of the year, rewarding those prepared for temperate conditions with prolific encounters: European Common Cuttlefish, Dogfish, Lumpfish, Cod, and Righteye Flounder are observed consistently across sites. Shore entry is possible at several sites, making independent diving straightforward.
Monthly water temperature across Funen's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperatures are at their lowest through winter and early spring, rising gradually from late spring into summer when conditions are most rewarding for diving. The warmest months run from July through September, coinciding with the best visibility and the highest activity among resident fish and cuttlefish. Sites in the straits can be subject to current, so timing dives around slack water is advisable at exposed spots such as Romsoe Rev.

Water temperature around Funen ranges from about 4°C in February to 16°C in August, based on satellite sea-temperature data for its dive sites.
In the warm season (about 16°C) a 7mm or semi-dry suit is comfortable in Funen; in the coldest months (about 4°C) step up to a drysuit.

Funen's sites consistently produce sightings of European Common Cuttlefish, Dogfish, Lumpfish, Cod, Needlefish, Righteye Flounder, Sand Eel, Sea Star, and Sea Anemone. European Green Crab and Hermit Crab are common on the seabed, and Pipefish and Conger Eel are observed at some sites. The European Common Cuttlefish is the region's signature species and is encountered across the full range of dive sites.
Several sites are rated for beginners, including the shore-accessible Svendborg Sundbroen and the shallow reef at Romsoe Rev. Both offer relatively modest depths and a mix of natural and artificial structure to explore. Intermediate divers are better placed for the wreck sites M/F Ærøsund and MTB 1, which involve boat access and benefit from some prior wreck experience.
Both options exist depending on the site. Svendborg Sundbroen offers shore entry, making it convenient for divers without access to a charter. Romsoe Rev can also be reached by either means. The wreck sites M/F Ærøsund and MTB 1 are boat-access only, so those sites require arranging watercraft independently as no operators are currently listed for the region.
Funen offers a combination of scuttled wrecks and reef diving, including both natural reefs and deliberately placed artificial reef structures. The ferry wreck M/F Ærøsund was purposefully sunk to serve as an artificial reef, while sites like Romsoe Rev provide shallower natural reef terrain. This variety means divers can move between wreck exploration and reef surveys within the same region.
