The high sets up a large E’ly fetch according to most recent model runs with a round of tradewind swell in the sub-tropics.

Not much in the way of swell generating wind in the Coral Sea short term so expect tiny/flat conditions for most of the week. Eventually the high pressure cell builds a tradewind fetch in the Coral Sea, likely by Fri, with surf building to rideable levels on Sat and likely extending into Sun.
This storm force low has a broad fetch aimed directly at the East Coast, but will be positioned too far south to generate much in the way of swell for CQ.
There’ll be plenty of swell from the lead-up work as well with an anchored trade fetch through the Coral Sea doing plenty of heavy lifting into Easter.
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 into the Coral Sea, enhanced by a trough of low pressure near New Caledonia which is attached to a still active monsoon trough.
High pressure is moving into the Tasman tomorrow in the wake of a front with a weak tradewind fetch and SE surge developing.
Nothing of any interest this week with weak pressure gradients in the Coral Sea and tiny/flat surf.
Mon Update- no change to outlook, tiny/flat this week as Tasman low dominates the space.
We’ll see a couple of fun days of surf from the initial tradewind fetch feeding into the trough for CQ.
High pressure will be in the Tasman next week with ridge along the sub-tropics and a tradewind fetch enhanced by a long monsoon trough extending from the Indian Ocean across the north of the continent out to the South Pacific Island chains.
