## Conditions at Underground

Underground is open to the sea from the **WSW–ENE**, so waves build there when the wind blows from those directions. Land shelters it from the E–SSW.

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

When it's rough here, try [Mary’s Place](https://scubaforecast.com/scuba-diving-weather/honduras/bay-islands/roatan/marys-place) (9.6 km, sheltered from the WSW–NE).

The water is warm to about 51 m.
