The high initially weakens with a lighter onshore flow before re-strengthening as it approaches New Zealand and has the pressure gradient tightened on the western flank by the complex trough systems. That will produce a N’ly flow, expected to increase as the week goes on with increasing NE windswell late in the week and early weekend.

That NE windswell looks to be persistent under the slow moving pattern with high pressure drifting towards New Zealand. We should see an uptick in size through the second half of next week.

The deep Tasman low near the North Island has now dissipated and left the building with a small low in the Central/Southern Tasman supplying some S swell and an even smaller trough of low pressure off the Far North Coast. This pattern remains slow moving as large high slowly approaches from South of the Bight and multiple inland troughs supply unstable weather.

The Tasman low of sub-tropical origins which has sprayed the East Coast with swell is now just north of the North Island, with some swell generating winds still active to the west of the North Island, although quite limited in length. It’s deepened and is hammering the North Island.

We’ve still got the building blocks in place for large swells across most of the Eastern Seaboard, with a large high , powerful frontal system, and deepening trough (still expected to form a surface low) in the Northern Tasman currently in play.

Spectacular charts more characteristic of late Summer/Autumn with a Cat 5 TC in the South Pacific bearing down on Vanuatu, and a powerful frontal intrusion poised to enter the Tasman Sea backed by a monster high in the Bight.

Late in the week, a combination of inland upper trough and a long angled trough extending from TC Lola remnants is expected to form a powerful surface low off the sub-tropical NSW Coast (likely between Lord Howe and Norfolk Is). As modelled, gales will produce a large E’ly quadrant swell event, with maximum size in Northern NSW, grading smaller into temperate NSW. A secondary October surprise that looks to be a major swell producer

No great change to the weekend f/cast. An approaching complex trough, front and low complex will see freshening N/NE-NE winds through Sat with only a brief period of light NW winds inshore early.

The synoptic set-up looks quite unseasonal at the moment with a 1031 hPa high drifting over NSW and a 1007 hPa low slow moving in the Tasman west of the North Island. Current ASCAT (satellite windspeed) passes show broad fetch of mostly strong S-S/SE winds with some embedded low end gales reasonably well aimed for East coast swell production.

A strong front and embedded trough of low pressure are currently located just off the Gippsland Coast, expected too move NE into the Tasman and driving a strong/ near gale force S’ly flow up the NSW Coast today, reaching the QLD in the wee hours of Tuesday. There’ll be an initial burst of S swell associated with the proximate fetch, with some better quality SE-E/SE swell from a secondary intensification of the low as it becomes slow moving near New Zealand.
