Swell Summary
Surf along south facing shores will trend up today as a long period southwest swell energy from the Tasman Sea arrives and begins to move through the area. This southwest swell should peak around Tuesday and will be followed by a small reinforcing south-southwest swell by Wednesday. The combination of these swells should produce small surf along south facing shores through the week.
Surf along east facing shores will remain rough and choppy each day due to the persistent fresh onshore breezes.
