Building swell energy with generally favourable and workable winds each morning over the coming days.

There's a window of cleaner conditions and fun swell for early next week before we settle back into an unfavourable pattern.

The pattern change we spoke about on Fri then kicks right in, with blocking high pressure in the North Pacific shunting storms northwards towards the Aleutian Islands.

New high pressure slips into the Tasman Thursday and immediately has the pressure gradient on the western flank tightened by an interior trough system. That sees a fast developing N to NE fetch off the Far South Coast and Gippsland build NE windswell off the NE Coast of Tasmania during Thurs.
