## Conditions at Castle Rock

Castle Rock is open to the sea from the **WNW–E**, so waves build there when the wind blows from those directions. Land shelters it from the SE–SSE.

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 [Siaba Besar](https://scubaforecast.com/scuba-diving-weather/indonesia/east-nusa-tenggara/komodo/siaba-besar) (16 km, sheltered from the N–E).

The water is warm to about 10 m.
