Porpoise Bay is one of the safer swimming beaches in the Catlins, offering a sheltered sandy bay with gentler conditions than nearby Curio Bay. However, water temperatures remain cold year-round (typically 10-15°C), so wetsuits are recommended. The beach is popular with surfers, particularly beginners, due to consistent but manageable waves. There are no lifeguards, so swim at your own risk and stay within your ability level. Be aware of rips and changing tides. The sheltered location makes it more family-friendly than exposed Catlins beaches.

Hector's dolphins, New Zealand's smallest and rarest dolphin species, are frequently spotted at Porpoise Bay year-round, though sightings cannot be guaranteed. Summer months (December-March) generally offer the best viewing opportunities with calmer seas and better visibility. Dolphins are often seen surfing in the waves close to shore, particularly during incoming tides. Early morning and late afternoon can be productive times. If dolphins are present, maintain a respectful distance and follow DOC guidelines—never swim directly toward them or attempt to touch them.
