High pressure is in the Tasman with three tropical cyclones currently on the map. NETas will see some smaller surf from these systems as well as NE windswell.

The trade-wind fetch is relatively robust and will be a long-lasting swell producer for the east coast, favouring sub-tropical areas for size with some small swell filtering down to NETas through the week.
High pressure has moved into the Tasman and sits there over the weekend. It’s quite a strong high (expected to strengthen from 1025 to 1030 hPa) with a typical wind signature for this time of year- mod/fresh SE winds in the sub-tropics, tending to NE winds in temperate NSW and extending down to Tasmania.
Following that, high pressure moving into the Tasman will supply another round of NE windswell over the weekend.
There's still a fun though inconsistent E/NE swell inbound ahead of small south swells, and a stronger N/NE windswell on the weekend.
We've got a mix of easing E/NE energy and building S/SE swell with decent winds.
An active monsoon pattern is seeing a tropical low drifting in the Coral Sea with a supporting high approaching New Zealand and a slow moving trough line just off the NSW Coast, directing strong N’ly winds down into Bass Strait and adjacent to Tasmania.
Thursday sees a solid spike in NE windswell as N’ly winds ramp up from the South Coast across Bass Strait and adjacent to NETas.
Surf builds into the new week as high pressure drifts SE of the Island and the trough stalls off the Southern NSW coast, directing SE-E winds at Tas and generating some chunky E/SE-E swell.
The next S’ly change pushes into Tas Fri before stalling, with a useful fetch of SE-E winds aimed up at East Coast Tas.
