Can be encountered year-round in most locations, though seasonal variations exist. Breeding seasons (typically summer) may limit access to some colonies. In the Galapagos, visibility is often best June-November. In Southern Australia, winter months (May-October) typically offer clearer conditions.
Typically temperate waters ranging from 12-22°C (54-72°F), varies by species and location. Galapagos sea lions inhabit warmer waters than other species.
Best encounters occur near established colonies. Prime locations include: Galapagos Islands (year-round, very playful), Hopkins Island and Baird Bay (South Australia), Hornby Island (British Columbia), La Paz (Mexico, winter), Palomino Islands (Peru), and Cabo Pulmo (Mexico). They're typically encountered in shallow water, often while snorkeling rather than diving. Young sea lions are naturally curious and playful, often approaching divers. Maintain respectful distance from beaches/rocks during breeding season when males can be territorial. Never chase them; let them approach you.
