## Conditions at Toilet Bowl

Toilet Bowl is open to the sea from the **WSW–N**, so waves build there when the wind blows from those directions. Land shelters it from the ENE–SW.

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 [Blue Cave](https://scubaforecast.com/scuba-diving-weather/japan/okinawa-prefecture/okinawa-island/blue-cave-okinawa-island) (9.9 km, sheltered from the WSW–WNW).

The water stays warm past 29 m.
