We’ll see the NE’ly flow continue to develop in the Northern Tasman and Coral Seas through this week, with swells from that E-NE quadrant building through this short term period under an onshore flow.

The dominant player is a massive high moving through the Bight and expected to drift over and eastwards of Tasmania tomorrow to occupy the Tasman for most of the week.
We may see a deepening trough and E/NE-NE infeed dip south later next week bringing some sizey E/NE-NE swell to Tas next weekend.
SE-E/SE swell is the main swell next week as the low remains slow moving in the eastern Tasman.
The weekend’s fronts and lows sweeping up from the south look to consolidate early next week into a much stronger system, backed by a strong high in the Bight.
The great run of east swell finally comes to a close over the weekend.
We should see some better quality, albeit small E/NE swell later next week from a new sub-tropical low which forms this weekend and then drifts out towards the North Island.
This slow moving fetch will maintain elevated E/NE’ly swells for the majority of this week with embedded pulses and only a very slow easing trend through the week.
O’night Sat into Sun the Coral Sea low will merge with the NSW low forming a deep and powerful low pressure system in the Northern Tasman.
A deep, complex low pressure system (see Beast from the East) then forms in the Tasman and slowly migrates towards the North Island with large E’ly swell pulses generated over a prolonged period.
