There is quite a strong front tracking across the lower Tasman in advance of this high cell, along with a polar low, which will send some useful S swells our way before the high sets up a blocking pattern, which is expected to be reinforced by another large high next week.
Primary tabs
We’ll see some small S pulses and NE windswell on the menu this week.
Winds shift more N’ly through Sun, then NW-W/NW and we’ll see some real size as the fetch reaches peak strength through the morning.
Sunday is looking very sizey indeed as the fetch ramps up with low end gales off the coast of Tasmania extending up towards Bass Strait and the Gippsland coast.
Another unstable, troughy week ahead with humid, unstable air over the continent creating a series of troughs, one of which forms a slow moving trough of low pressure off the Mid North Coast which interacts with a weak high pressure cell drifting in the Tasman. That will supply some workable E/NE quadrant swell along with more local E swell.
S’ly groundswell is currently being generated by a slow moving polar low on the far edge of the swell window well to the SW of Tasmania. Most of this swell is better aimed at the southern states and South Pacific targets but we will see some refraction into the East Coast of Tasmania
A powerful low below the continent this weekend promises a flukey south groundswell while we should see a notch more short period E/NE swell next week from a slow moving trough/low in the Tasman.
We’ll be relying on some small NE windswell episodes and great circle paths under the continent to deliver some flukey S groundswell short and medium term.
The freshening N-NE flow along the NSW temperate coast should generate some NE windswell through Wed PM, peaking Thurs
Some modest frontal activity pushes through late in the week with a developing N’ly flow on Sun set to provide some NE windswell.
