## Conditions at Gina

Gina is open to the sea from the **WSW, NW–N**, so waves build there when the wind blows from those directions. Land shelters it from the NNE–SSW, WNW.

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

When it's rough here, try [Amuro Gyosho](https://scubaforecast.com/scuba-diving-weather/japan/okinawa-prefecture/zamami/amuro-gyosho) (3.0 km, sheltered from the WSW, NW–N).

The water stays warm past 56 m.
