## Conditions at Hin Wong Pinnacle

Hin Wong Pinnacle is open to the sea from the **NW–SSE**, so waves build there when the wind blows from those directions.

Over the next 7 days it's good or better every day. Thu and Fri are only a trend so far.

When it's rough here, try [Mae Haad](https://scubaforecast.com/scuba-diving-weather/thailand/surat-thani/koh-tao/mae-haad) (4.6 km, sheltered from the N–SSE).

The water stays warm past 34 m.
