## Conditions at Manta Bay

Manta Bay is open to the sea from the **S–WNW**, so waves build there when the wind blows from those directions.

Over the next 7 days no day looks good: Sun and Mon are a no-go (surge). Thu and Fri are only a trend so far.

When it's rough here, try [Batu Mulapan](https://scubaforecast.com/scuba-diving-weather/indonesia/bali/nusa-penida/batu-mulapan) (15 km, sheltered from the S–WNW).

The water is warm to about 10 m.
