## Conditions at HMNZS Canterbury

HMNZS Canterbury is open to the sea from the **W–NNW**, so waves build there when the wind blows from those directions. Land shelters it from the N–S.

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

The water is warm to about 6 m.
