Key Dive Site Facts
Dive Site Overview
Carnoch Bay stands out as a highly versatile Scottish dive site, catering to a broad spectrum of diving proficiencies from beginner to technical levels. Its unique topography includes a sheltered inner bay, ideal for skill practice and initial open water dives at depths generally around 15 m / 50 ft, where the sandy bottom requires careful finning to maintain visibility.
Beyond this protected area, divers can explore more challenging outer sections where the seabed progressively drops, reaching well beyond 30 m / 100 ft and even up to 50 meters in certain areas. A prominent slate wall, often kept on the right shoulder during outward finning, forms a key navigational feature, offering a substantial guided dive that can extend for over two hours if exploring leisurely.
This diverse environment allows for various dive types, including reef, sea loch, and wall diving from either the stoney beach or a short walk to a point for deeper access. A large car park next to the entry point and nearby accommodation further enhances its appeal, making it an excellent location for club weekends or day trips, accommodating a higher number of divers without feeling crowded.
Its range of options truly makes it accessible to both new divers taking their first breaths and experienced enthusiasts seeking depth.
Best Time to Dive
For an optimal dive experience at Carnoch Bay, consider visiting during the spring through autumn months, specifically from March to September. This period consistently registers 'Good' dive scores in local assessments. Air temperatures during these months typically range from 6-15°C / 43-59°F, creating more comfortable surface conditions for dive preparations and post-dive activities. Rainfall tends to be lower in spring, particularly in May with an average of 3.7 mm, reducing the likelihood of surface runoff impacting underwater visibility. While diving is possible year-round, conditions in months like December and February show higher rainfall, averaging 11.4 mm and 7.5 mm respectively, and lower air temperatures. Generous parking and proximity to local amenities make it especially suitable for group outings or club weekends when surface logistics are a consideration.

Dive Experience & Conditions
Dive profiles at Carnoch Bay vary significantly, starting with a gentle slope from shore entry points, which can be around 7-8 meters deep depending on the tide. Within the bay itself, depths generally remain typically 12-15 meters, providing a controlled environment for training or shallower exploration. For those seeking greater depths, finning out from the bay or initiating the dive from a further point on the shore reveals a seabed that progressively drops beyond 30 meters, potentially reaching up to 50 meters. Following the prominent slate wall on your right shoulder is a common navigation method, leading divers along the reef structure. Bottom composition in shallower areas is often sandy, requiring careful buoyancy control to avoid reducing visibility. Water temperatures are typical for a Scottish sea loch, varying with the seasons.
Dive Difficulty & Safety Guidelines
Divers at Carnoch Bay should always prioritize safety by being mindful of potential boat traffic, especially when moving beyond the immediate bay area; deploying a Surface Marker Buoy (SMB) is strongly recommended. Given the site's varied depth profiles, from shallow training areas to technical depths of 50 m, maintaining excellent buoyancy control is crucial to prevent stirring up the sandy bottom and preserving visibility. For deeper or offshore exploration, utilizing a sounder to locate the main reef structure can be beneficial. While most mobile networks offer service here, always have a contingency plan for communication. Dive with appropriate gas mixtures, such as Nitrox, for extended bottom times or specific depth goals.
