Models are holding steady on a winter calibre low tracking well to the south- south-east of Tasmania during Sun and traversing the far Southern Tasman through Mon.

Some quiet days then follow before a much more robust front and low enter the lower Tasman late in the weekend driving some sizey S swell up the coast early next week.
We’ve got a weak, troughy pattern in the Tasman Sea, with a minor cold front passing to the SE of Tasmania and a new high pressure cell poised to enter the Tasman in it’s wake. The high cell is weak so we’re looking at a fairly uninspiring end to Summer, with some mid week NE windswell for Southern NSW and small background E swells for the sub-tropics.
High pressure in the Bight with a trough moving up the coast and robust low (974hPa) moving under Tasmania sets the scene for the weekend.
The rest of the week looks pretty fun.
Lots of fun beachbreak surf on tap for this week.
High pressure belt remains strong with cells lined up to enter the Tasman. A monsoonal low in the Gulf of Carpenteria is generating a long cloud band down the east coast. A long, broad E’ly tradewind fetch extends from the Coral Sea into the South Pacific with the tail of the fetch in Tahitian longitudes.
Our current pattern of slow moving high pressure near New Zealand is still well entrenched with a modest cold front sweeping into the Tasman and bringing a S’ly change to temperate NSW. Multiple cells of reinforcing high pressure then one by one move into the Tasman, maintaining a weak ridge up the NSW Coast and a deep E’ly flow through the South Pacific and Eastern Coral Sea, with resulting E’ly swells favouring the sub-tropics for size.
Large high in the Tasman directing plenty of E’ly-SE’ly tradewinds through the Coral Sea and South Pacific slot. Typical summer wind pattern with NE winds developing across temperate NSW, tending more E-E/SE in the sub-tropics.
We’ve got a very strong high pressure belt at the moment with a cell in the Tasman (twin cells actually, straddling New Zealand) and monster high moving in from the Bight. A trough off the NSW coast is focusing SE winds along the Eastern Seaboard, with a strong front/low traversing the Lower Tasman.
