## Conditions at Gamat Bay

Gamat Bay is open to the sea from the **NNE, SW**, 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 [Mangrove](https://scubaforecast.com/scuba-diving-weather/indonesia/bali/nusa-penida/mangrove) (4.3 km, sheltered from the SW).

The water is warm to about 10 m.
