Some decaying and fast moving frontal activity in the lower Tasman is currently scooting across that sea. Once the new high sets up shop in the Tasman we’ll see the N-NE flow which has been a constant for a month reset until another S’ly change arrives on the weekend. No major swells ahead as the pattern of weak, mobile high pressure continues but there’ll be some windows of opportunity with small NE windswell and minor flushes of S swell.

No change to the weekend f/cast. We’ll see the N-NE flow re-strengthen on Sat as a large high slips in under Tasmania and multiple troughs and a cut-off low forming over the interior tighten the pressure gradient along the coast.

As a result, we’re looking at small NE windswells for temperate NSW, with trade swells for the sub-tropics and a marginal amount of that swell filtering down to temperate regions.

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.
