Kaikoura Dusky Dolphin Swim

The encounter

Species / spectacle: Wild dusky dolphins in large super-pods sometimes numbering hundreds; the swim is with free-ranging animals that choose to interact. NZ fur seals and seabirds often seen.

How you see it: swim

Typical duration: Around three hours total including briefing, wetsuit fitting and boat time. (Confirm.)

When to go

Dolphins come closer inshore roughly October to May with summer November to March best. Present year-round but conditions harder and colder in winter.

Best time of day: Early morning trips typically have calmer water and more interactive dolphins. (Confirm.)

Peak summer super-pods and calmer seas; occasional other cetaceans and abundant fur seals in warmer months.

Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.
