These lows will coalesce to form a large primary system by Sunday, but the resulting swell will still be too westerly for the South Arm on Monday.
There’s a whole stack of swell on the way too, though initially it’ll be very westerly in direction, originating from a powerful low spinning up immediately south of West Oz that’ll drive a strong front through the Bight.
TThe associated fetch is lining up in the best part of the Vicco swell window (relative to surf size and consistency), and will remain slow moving as it reaches maturity, drawn out over an impressive 30-odd hours or so, which helps to exaggerate eventual surf size above the usual model expectations. It's not a common event.
Into next week and a compact but powerful cut-off low approaches the state early next week. Early incarnations of the low aim up severe gales generating a strong W/SW pulse Tues.
Further south the NE swell is now on the wane, with some surfable leftovers on offer over the weekend.
Pumping surf across the region since the last f/cast with more to come over the weekend.
The fetch of deep E to E/NE winds in the Coral and Northern Tasman Sea is contracting northwards around a surface low off the CQ/Fraser coast, and expected to fizzle out over the weekend. At present gales are retrograding towards the QLD, generating large swells.
No great change to the weekend f/cast. The fetch of deep E to E/NE winds in the Coral and Northern Tasman Sea is contracting northwards around a surface low off the CQ/Fraser coast, and expected to fizzle out over the weekend.
A deep polar low is tracking NE from E of Heard Island today, with a long trailing fetch of SW gales and seas in excess of 20ft in a wide swathe. Iterations of this storm system will bring strong pulses of SW swell over the next few days and into the weekend, with onshore winds a problem.
The models have slowed Friday’s frontal passage, which has delayed the weekends inbound westerly swell.
