The Beagle Channel is a sub-Antarctic waterway accessed from Ushuaia, and its diving is defined by giant kelp forests, cold water, and rich benthic life. Sites range from shallow shore entries to boat-only locations such as Isla de los Lobos, sixty kilometres offshore. Water temperatures sit between roughly two and ten degrees Celsius, making a drysuit standard. Visibility can reach twenty metres at sites such as Sea Lions Island. Marine life includes South American sea lions, king crabs, sea urchins, sea stars, nudibranchs, squat lobsters, and East Pacific red octopus.
Monthly water temperature across Beagle Channel's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water is cold throughout the year, typically between two and ten degrees Celsius, so a drysuit is the practical minimum for all but the most brief dives. Visibility varies by site from around seven metres up to twenty metres, generally clearest at exposed offshore sites.
Water temperature around Beagle Channel ranges from about 4°C in June to 8°C in January, based on satellite sea-temperature data for its dive sites.
With water around 4–8°C, a drysuit works in Beagle Channel year-round.
