## Conditions at Portsea Pier

Portsea Pier is open to the sea from the **NNE, ENE–E**, so waves build there when the wind blows from those directions. Land shelters it from the ESE–WNW.

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 6 m.
