Tikehau is defined by its shark encounters and large pelagics. The Whitetip Reef Shark, Grey Reef Shark, and Reef Manta Ray are observed across nearly every site, while the Napoleon Wrasse is a constant presence. Te Ava Drift brings wall, canyon, and drift diving in a single drop, whereas shallower sites like Blue Lagoon and Rangiroa Blue Lagoon keep things accessible for beginners. Visibility varies considerably, and the cooler months tend to produce the clearest water.

Water stays warm year-round, peaking in the early months of the year and dipping slightly through the cooler mid-year period. The best-months data points to a pronounced peak from August through October, when visibility tends to improve and pelagic activity is strong. Drift diving at sites like Te Ava Drift benefits from tidal flow through the atoll passes, so conditions shift with the tide rather than the season.
