We’ll see the wind flow strengthen on Sat as a large high slips in under Tasmania and multiple troughs and a cut-off low forming over the interior tighten the pressure gradient proximate to Eastern Tasmania.

E’ly winds feeding into the cut-off low are aimed directly at NETas and will produce sizier swells into Fri.

There is quite a strong front tracking across the lower Tasman in advance of this high cell, along with a polar low,  which will send some useful S swells our way before the high sets up a blocking pattern, which is expected to be reinforced by another large high next week.

Winds shift more N’ly through Sun, then NW-W/NW and we’ll see some real size as the fetch reaches peak strength through the morning.
