Late Wed will see the next increase in swell and the system responsible, a polar low which intensifies as it passes Heard Island Sun, now looks stronger and less zonal, with a swathe of 30ft seas sending groundswell to WA.
It's a tricky weekend of waves ahead. But there are items worth monitoring.
Dynamic weekend f/cast ahead as a strong NE fetch builds a chunky windswell and a trough then brings an extended period of elevated wave heights from the SE to E.
Very dynamic weekend forecast ahead as a low pressure trough forms off the CQ coast today and forms a small surface low which drifts south to hug the coast over the weekend, accelerating away to the south through early next week.
A trough of low pressure off the QLD Coast forms a small surface low over the weekend and this moves south Mon, interacting with a strong high moving south of Tasmania and another interior low forming in a trough line late in the weekend. This potent brew intensifies the NE-E/NE fetch forming in the Coral Sea and drags it south, where it more directly impacts temperate NSW.
We’ve got a couple of small swells inbound over the next few days, but Sunday has the most potential.
We’ve got a couple of small swells inbound over the next few days; a minor bump in size for Thursday and a slightly bigger pulse Friday.
A long, zonal fetch of gales reaches peak strength as it passes Heard Island Sun/Mon and this should generate a mid-sized, mid period SW swell building in Thurs into the 4-5ft range in the Margarets region, smaller 2-3ft in Mandurah, 2ft in Perth, and easing through Fri.
The onshore flow is enhanced into a deeper tradewind flow up in the Coral Sea, which gets a boost from a trough of low pressure expected to form off the Central QLD Coast this weekend before drifting south as a surface low, bringing sizey swell from the East and dynamic weather. The trough of low-pressure from inland Victoria is expected to drift SE of Tasmania over the weekend with plenty of swell expected.
