Diving in Los Lagos

Los Lagos covers a stretch of Pacific coast and estuarine channels in southern Chile, taking in fjord-adjacent waters that are cold and relatively unexplored by visiting divers. The four sites in the database include reef, wall, kelp forest, and drop-off terrain, with Cantil del Mareado dropping to sixty metres. Water temperatures peak in the mid-teens Celsius in summer and fall toward ten degrees in mid-winter, requiring drysuits or heavy wetsuits throughout much of the year. Species recorded across the sites include broadnose sevengill sharks, blue sharks, south American sea lions, king crabs, torpedo rays, and gorgonians, and seven operators work out of Puerto Montt.

Water temperature in Los Lagos

Monthly water temperature across Los Lagos's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.

Water cools to around ten degrees Celsius between July and September and climbs only to the mid-teens in the warmest months, so drysuits are the practical default for most divers. The deep wall at Cantil del Mareado reaches sixty metres and requires solid buoyancy control, while shallower reef sites at Isla Quenu and Caleta la Arena are accessible to open water divers. Diving infrastructure is modest, and the region is oriented towards those comfortable in cold, less-trafficked conditions.
