Offshore Chennai reef with swim-throughs and current.
Offshore Chennai reef with swim-throughs and current.
Offshore dive that is best run through a local operator because timing and sea state matter.
Cozy Canyon is an offshore Chennai dive built around swim-throughs and compact reef structure, with enough fish life to keep the route busy rather than sprawling. It suits divers who are comfortable holding trim through tighter sections and adapting to changing water movement. Expect visibility and current to swing with sea state, so the best dives come when the water settles and the operator can time the window well.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.

Up to 17m
Depth Note
Rough max depth is about 17m; the shallow start is not consistently documented.

Winter, with strong windows in March-April and October-November.
Typical Conditions
Variable visibility and strong current are normal; calmer seas can improve the swim-through sections and overall comfort.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Be prepared for potentially strong currents and variable visibility. Swim-throughs may require good buoyancy control and awareness of overhead areas.
Community notes to help plan your visit.
Scuba Diving
Boat-based Chennai reef dive with swim-throughs, compact structure, and a need to stay comfortable in current and changing visibility.
Freediving
Not the best freedive target. The offshore setting, current, and swim-throughs make it a better fit for scuba than casual breath-hold sessions.
Snorkeling
Snorkeling is secondary at best; the site is more useful to divers who can handle current and tighter underwater sections.
