Not a great change through the rest of the week with the trough devolving into a trough line and sitting on the coast and a new trough of low pressure forming on the weekend. We’ll see some new short range S swell from that source, improving in quality as the trough forms a low and moves away from the coast.

We’ve got a more subdued synoptic outlook this week with weak high pressure currently in the Tasman and a complex troughy area of low pressure situated off the Southern NSW/Gippsland coast. That trough moves NE, backed by a large high pressure centre currently in the Bight. We’ll see the trough bring onshore winds and swell as it moves up the NSW Coast through the first half of this week.

The large mid-latitude low in the central Tasman Sea - responsible for today’s very large surf - is slowly rotating clockwise, and by this evening won’t actually have a fetch aimed within our swell window.

A tropical depression between Vanuatu and New Caledonia has formed a tropical cyclone (TC Tam) and is racing south-eastwards at 23kts, where it is expected to merge with another tropical low SW of New Caledonia. After a binary interaction between the two systems, the merged low transitions into a storm force sub-tropical low which tracks SW into the Northern Tasman.

Certainly by Thurs the synoptic chart should look insane with a deep low (970-980hPa) retrograding into the Tasman, positioned inside the North island with plenty of space for severe gale to low end storm force winds to be aimed up at the east coast.

It's a bit of a tricky weekend of waves, but the short version is there should be something fun and it’ll be clean on top.

High pressure is moving into the Tasman, strengthening as it drifts towards New Zealand, where it is expected to become a dominant “flat topped” feature, reinforced by subsequent high pressure moving into the Tasman. We’ll see a long E’ly fetch develop through the South Pacific slot through the end of this week, enhanced by a trough of low pressure near New Caledonia which is attached to a still active monsoon trough.

A front passes into the Tasman overnight and robust fetch of SW gales is trailing behind, currently sweeping NE past the SE coast of Tasmania.

Monday and Tuesday will almost mirror the weekend’s swell pattern, with generally light winds and sea breezes expected both days - so better conditions on the balance.

We’ll see the low meander towards the South Island for the remainder of the week, with large swells on the ease across Southern/Central NSW, much less size into the sub-tropics.
