Models are now firming on a trough of low pressure forming near the North Island early next week and retrograding in a SW direction back towards the Eastern seaboard.

Pressure gradients will now slowly ease as the low starts to dissipate and the strong high weakens as it moves South of Tasmania through tomorrow. As this swell generating pattern breaks down we’ll be left with a weak, troughy pattern coming into the Xmas weekend with no major swell sources on hand, so you’ll need to get your grovel boards ready for Santa.
A reintensification of the Tasman Low on Saturday and Sunday - further east, near New Zealand - will generate a renewal of strong S/SE thru SE swell for Monday.
That's right, we're looking at a week of waves from a single swell source.
The next round of swell will be acute from the south, sourced from W/SW gales exiting eastern Bass Strait from this evening onwards, in associated with the same change that rocketed across the coast this afternoon.
The real juice is lining up from the E/NE later next week.
No major changes to the forecast for the rest of the week, if anything an upgrade in size for the next south swell.
This change will be linked in with a low off the eastern Tasmanian coast, and gale force S/SW winds will develop through the swell window, generating a decent southerly swell for Wednesday
A slow moving low pressure system is currently off the QLD coast generating plenty of size for the subtropics. Windspeeds along the southern flank are just a notch higher than modelled on Wed so we’ll see a corresponding uptick in size across the f/cast region as swell radiates away from the source fetch.
Small swells and onshore winds into the weekend with some potential for juicier surf later next week
We are seeing the “schizoid” pattern now develop whereby a monsoonal trough is splitting off a low pressure trough along the CQ coast, supported by a high pressure belt from the Bight to the Tasman Sea, while fronts and a parent low are entering the lower Tasman. That is seeing a regime where both S swells and a developing E’ly swell event are both in play across most of the Eastern Seaboard.
