## Conditions at Aragusuku Ryugu no Ne

Aragusuku Ryugu no Ne is open to the sea from the **NE, SE, SSW–W**, so waves build there when the wind blows from those directions. Land shelters it from the ENE–ESE, SSE–S.

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 [Kohama West Suzumedai House](https://scubaforecast.com/scuba-diving-weather/japan/okinawa-prefecture/ishigaki/kohama-west-suzumedai-house) (14 km, sheltered from the SE, WSW–W).

The water stays warm past 29 m.
