## Conditions at Kuroshima V-ji II

Kuroshima V-ji II is open to the sea from the **E–WSW**, so waves build there when the wind blows from those directions. Land shelters it from the NNE–ENE.

Over the next 7 days it's good or better on Mon, Tue and Wed. 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) (15 km, sheltered from the E–SSE, WSW).

The water stays warm past 56 m.
