The high pressure belt is weak and moving at a more N’ly latitude than we’ve seen this summer, with a troughy pattern in the Tasman and some frontal activity under the SE of the continent continuing. A much stronger front and parent low tracks NE into the lower Tasman late this week with a broad band of gales to strong gales expected to generate some strong S swell over the weekend.

The coming period is very dynamic and complex but in short there's a ton of swell inbound with good wind windows.

There's a ton of swell due this period, it's just working the winds in between fronts.

Fri should be a different story. Strong S swell expected to build Fri and extend into Sat as a front with gales to strong gales tied to a complex parent low drifts slowly through the far Southern Tasman.
