Once the new high sets up shop in the Tasman we’ll see a weak E’ly flow set up in the Coral Sea which will generate a tiny, just rideable surf into the weekend.

High pressure is moving eastwards, dragging the trade fetch with it. Weak high pressure moves into the Tasman later this week. No major swells this week, so we’ll be relying on our persistent trade-swell, which looks to ease back to tiny/flat mid-week as the fetch retreats eastwards.
A high pressure belt in the sub-tropics maintains a long Easterly fetch with tradewinds chugging away supplying fun surf over the weekend.
A tradewind flow focussed around the New Caledonia area and out into the South Pacific slot will maintain fun E’ly tradewind surf in the sub-tropics.
High pressure remains a constant in the Tasman, with a reinforcing cell ready to slide under Tasmania late week. A heat low over NW Australia and trough are linked to a cut-off low in the Bight which gets squeezed out by high pressure. As a result workable trade swells for the sub-tropics continue through this week.
A broad but weak E'ly tradewind fetch occupies the Coral Sea, producing some workable E'ly swell.
That will be the dominant feature of our synoptic set-up for some time, which sees high pressure in the Tasman and a firm ridge up the sub-tropical coast and broad fetch of E-E/SE winds in the Coral Sea.
We’ll see a strong high edge in from the Bight early this week and take up residence in the Tasman Sea, with a broad and persistent Tradewinds fetch developing in the Coral Sea. We should see just rideable surf through Tues and Wed ramp up on Thurs as windspeeds increase in the Coral Sea.
Better signs ahead as a stronger high approaches Tasmania later next week, building a stronger ridge and a better tradewind coverage in the Coral Sea from Wed.
We’ll see a new high move into the Tasman over the weekend with a SE surge developing up the Tasman and into the Coral Sea. That should see some rideable surf develop under SE-E winds through Sun into Mon and extending into Tues before easing.
