## Conditions at Tuna Wreck

Tuna Wreck is open to the sea from the **NNE–SSE, SSW–SW, NW**, so waves build there when the wind blows from those directions. Land shelters it from the WSW–WNW, NNW.

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

The water is warm to about 35 m.
