## Conditions at Ozone wreck

Ozone wreck is open to the sea from the **NNE–SE**, so waves build there when the wind blows from those directions. Land shelters it from the SSE–NW.

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

The water stays warm past 13 m.
