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.
Fairly favourable winds with easing surf from today, increasing again from late week.
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.
The tradewind flow through the Central/Southern Coral Sea gets a boost later this week and into the weekend as a tropical low forms between Vanuatu and New Caledonia.
A trough of low pressure has drifted south-westwards from the South Pacific into the area west of the North Island and looks a touch healthier than it did during Friday.
A slow moving trough with two embedded lows will move in from the west along with no decent swell. There's a bit more action into the weekend but with less than ideal winds.
The charts will be looking good as low pressure steams around the corner from New Caledonia and drops into the slot but we won’t see swell from that until the following week.
There's no major surf or swell due this week but we'll see a bit more action from Sunday into next week.
A major pattern change occurs next week with the intense storm track of the last month which has seen two huge cyclone gyres forming, and relentless storms charging at Hawaii, breaking down.
The blocking pattern remains in place for most of next week. First, the initial high maintains position just East of Tasmania with weak pressure gradients and only light N to NE winds in the swell window- not enough to generate any more than a foot or so of weak windswell.
