## Conditions at Shark’s Mouth

Shark’s Mouth is open to the sea from the **SSW–NNW**, so waves build there when the wind blows from those directions. Land shelters it from the N–SE.

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

The water is warm to about 50 m.
