Always true for this destination
- Alofi, the southwest coast and northwest tracks all experience ocean swell, but the exposed east side is less useful as an alternative snorkel shore.
Seasonal cautions
- Apr, Nov: Transitions between tropical wet and drier periods; sudden swell and rain still possible, especially in November.
- Dec to Mar: Warmer and more humid wet and cyclone season; official 2026-2027 outlook warns of elevated cyclone risk.
