Set in the southwest of England, Cornwall offers a unique diving experience thanks to its location between the Celtic Sea and the English Channel. The northern coastline, lapped by the Celtic Sea, presents a more rugged and exposed environment, perfect for those seeking adventure among its stunning beaches. In contrast, the southern coast, often referred to as the “Cornish Riviera," boasts calmer waters, making it ideal for divers of all skill levels, including families. Here, dramatic granite cliffs and tranquil bays set the stage for a diverse range of underwater explorations.
Diving in Cornwall is an experience defined by its variety and richness. From shallow shore dives perfect for beginners to thrilling boat dives that explore local reefs and historic wrecks, there is something for everyone. Advanced divers can venture into deeper waters to discover fascinating wrecks, remnants of maritime history. With popular diving bases in coastal towns like Newquay, Falmouth, and Penzance, divers can easily access some of the region’s best sites. During the summer months, Cornwall's waters become a vibrant playground, teeming with marine life, including seals, basking sharks, and a myriad of fish species, offering unforgettable encounters beneath the waves.
For those planning a summer dive holiday in Cornwall, early accommodation bookings are recommended, as this seaside county is a favorite among families. Whether you're diving among the bustling marine life or exploring the eerie silence of a shipwreck, Cornwall promises an engaging and memorable diving adventure.
Cornwall offers a diverse range of dive sites, making it a haven for both beginner and experienced divers. Notable wreck dives include the "HMS Scylla," a sunken naval frigate, providing an artificial reef teeming with marine life. The "James Eagan Layne," another popular wreck, offers a fascinating structural exploration in relatively shallow waters, suitable for divers of varying skill levels.
For those who prefer shore diving, sites like "Porthkerris" offer easy access to abundant marine life, including colorful anemones and playful seals. Unique experiences such as night dives reveal nocturnal behaviors of fish and crustaceans, adding an adventurous element. While Cornwall's dive sites primarily support shore diving, liveaboard options are available for those seeking more remote and extended dive adventures along the scenic coastline.
Diving in Cornwall is possible year-round, but conditions vary across seasons. In summer, water temperatures range from 14°C–18°C/57°F–64°F, offering pleasant diving conditions. Winter waters can drop to 8°C/46°F, requiring appropriate thermal protection. Visibility is typically better in late spring and early autumn, often reaching 10 meters/33 feet.
Weather factors such as wind and currents significantly affect diving conditions. The southwest coast is more exposed to Atlantic swells, making it crucial to check forecasts. Summer sees calmer seas, while autumn and winter can bring stormier conditions, impacting dive plans. Despite these challenges, with proper planning, Cornwall offers rewarding diving experiences throughout the year.
