That marks the emergence of another major system, as the remnants of the trough/low get re-energised by another upper disturbance being pushed Eastwards by a high in he bight. More on this later it’ll generate hepas of swell next week once it spins up.

This is maintaining a deep E’ly flow, with coastal troughs and a surface low off the NSW North Coast, now moving South.
Lots of action next week. We’ve got a stack of strong E to E/NE swell incoming- with some model variability suggesting we’ll need some further fine tuning next week.
This will be generated by the increasing E to E/NE winds in the deep E’ly wind field retrograding S and W towards NSW as a large area of tropical low pressure off the QLD coast starts to deepen and move S.
The latter part of the week will see a NE flow develop, with periods of light NW breezes inshore. Trade flows across the South Coral and Northern Tasman Sea won’t be particularly strong this week but the broad scale coverage of winds will be enough to see a modest building trend into Thurs and Fri.
The southerly change pushing up Southern NSW this afternoon doesn’t have a lot of strength nor longevity in its fetch, but we do have some swell potential for the weekend.
The swell window’s a little quiet at the moment, so we’re not expecting much surf for the rest of the week.
We’re looking at a steep easing trend and a week of small surf as high pressure moves a little more northwards than it has so far this La Niña Summer. Under the influence of the high pressure belt it’ll be a week of N to NE’ly winds and a small blend of E’ly swell trains.
Models now show the remnants of the cyclone undergoing extra-tropical transition as it slides towards New Zealand with areas of severe SE gales developing on the south-western quadrant.
Another strong ridge is expected to establish Fri with (another!) tropical low drifting south from the South Pacific later this week and over the weekend down the Tasman Sea pipe.
