Yes: Taha'a's coral garden is a shallow drift snorkel between two motu and Paipai Pass is a 25–30 m drop-off for trained divers, according to Tahiti Tourisme, but anchoring is restricted in parts of Moorea and we could not verify the current zones. The sea averages between 26.7 °C (August) and 29.0 °C (March) by NOAA's 1991–2020 means at our reference point, so it stays at 24 °C or more all year and by our rule of thumb a rash vest or 1–2 mm shorty is enough even in the coolest month.

Snorkel and dive sites you can reach by charter boat in French Polynesia
| Site | Type | Where | What the source says |
|---|---|---|---|
| Taha'a coral garden (Jardin de Corail) | coral garden | West side of Taha'a, between two motu | Tahiti Tourisme describes crystal-clear shallow water between two motu on the west side of the island, where you drift with the current over the coral. (Tahiti Tourisme) |
| Paipai Pass | reef and pass | Taha'a | Tahiti Tourisme describes a drop-off at 25–30 m for trained divers, with white-tip reef sharks; Taha'a has one dive centre and centres on Raiatea also dive there. (Tahiti Tourisme) |
These are the sites we could document from official or labelled sources, not a full list. Fishing is a separate question: fishing rules in French Polynesia.

Underwater visibility
Tahiti Tourisme says visibility reaches up to 40 m at Taha'a's outer-reef sites (Ruutai, Tau Tau, Taputapu). This is the tourism board's description, not a measured average. (Tahiti Tourisme)
What wetsuit do I need in French Polynesia?
From March's 29.0 °C our rule of thumb gives a swimsuit or rash vest; in August (26.7 °C) a rash vest or 1–2 mm shorty. The month-by-month column is in the table above.
Our rule of thumb for snorkelling, applied to the monthly mean: 28 °C or more: swimsuit or rash vest; 26–28 °C: rash vest or 1–2 mm shorty; 24–26 °C: 3 mm shorty; 21–24 °C: 3 mm full wetsuit; 18–21 °C: 5 mm full wetsuit; below 18 °C: 7 mm wetsuit, or a drysuit for diving. Divers lose heat faster and meet cooler water at depth: go one band thicker. People feel cold differently; this is a guide, not a source's advice.
| Mean sea temperature | Our rule of thumb for snorkelling |
|---|---|
| 28 °C or more | swimsuit or rash vest |
| 26–28 °C | rash vest or 1–2 mm shorty |
| 24–26 °C | 3 mm shorty |
| 21–24 °C | 3 mm full wetsuit |
| 18–21 °C | 5 mm full wetsuit |
| Below 18 °C | 7 mm wetsuit, or a drysuit for diving |

Frequently asked questions
Can you snorkel and dive from a charter boat in French Polynesia?
Yes: Taha'a's coral garden is a shallow drift snorkel between two motu and Paipai Pass is a 25–30 m drop-off for trained divers, according to Tahiti Tourisme, but anchoring is restricted in parts of Moorea and we could not verify the current zones. The sea averages between 26.7 °C (August) and 29.0 °C (March) by NOAA's 1991–2020 means at our reference point, so it stays at 24 °C or more all year and by our rule of thumb a rash vest or 1–2 mm shorty is enough even in the coolest month.
