Nai Harn

Nai Harn, Phuket, Thailand7.776° 98.306°
Levels 3-6

The southern tip of the island, and the punchiest of the three. The north head throws a crumbly right-hander; the south end in front of the lagoon gets fast and hollow and will barrel on the biggest days of the monsoon.

Times on this card are local to Nai Harn. The star call is our own estimate, calculated from the forecast height, period and wind speed — not measured, and not a suitability or safety assessment.

Calculated by us from the height and period above, not measured — and it describes the swell offshore, not the wave at the break.
