## Conditions at Kohama North Oranda

Kohama North Oranda is open to the sea from the **SE, WNW–NE**, so waves build there when the wind blows from those directions. Land shelters it from the 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 [Nagura Akakukuri no Ne](https://scubaforecast.com/scuba-diving-weather/japan/okinawa-prefecture/ishigaki/nagura-akakukuri-no-ne) (15 km, sheltered from the WNW–NE).

The water stays warm past 56 m.
