## Conditions at Racha Noi South Tip

Racha Noi South Tip is open to the sea from the **NE–N**, 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 [Siam Bay](https://scubaforecast.com/scuba-diving-weather/thailand/phuket/racha-islands/siam-bay) (19 km, sheltered from the ENE–WNW).

The water is warm to about 31 m.
