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.
That low looks to be a monster of a system. As the deep low moves eastwards towards the North Island it aims up gales to severe gales back towards the east coast and we’re on track to receive some powerful swell from the E/NE through next week.
High pressure has drifted up over NENSW and into the Tasman and an approaching trough and cut-off low really ramps up the pressure gradient short term, leading to fresh/strong N/NE-N’ly winds off the coast.
We’ll see the current pattern repeat as a pre-frontal N’ly flow ramps over the weekend before a front and low bring a stiff W’ly change.
We’ll see N’ly winds increase short term and then as we head into the weekend in response to an approaching cut-off low in the Bight, with sizey pulses of NE windswell on the radar for these periods.
