A low in the Tasman is moving north with a slingshot fetch of S-SE winds expected to rebuild wave heights from the S-SE later today and into tomorrow while a trough of low pressure in the Coral Sea is sending more E’ly angled swell into the sub-tropical Points. The combination of low and high pressure is maintain a firm ridge along the eastern seaboard with plenty of S-SE wind. 

 Late afternoon is on target for a sneaky long range/long period pulse of southerly groundswell, sourced from a tight but intense polar low skirting the ice shelf this weekend.

The Tasman Sea, by contrast, is looking very mellow with a weak high pressure cell over NSW and a few decaying remnants of the long lasting Tasman Low sitting near New Zealand. Those weak pressure gradients across our main S-SE swell window will lead to a very quiet week swell wise, with mostly offshore winds.

995 hPa low still sitting in the Central Tasman, but the supporting high pressure cell has slipped in underneath the low and as a result we’re seeing a slowly diminishing fetch and easing pressure gradients both in the Tasman and along the coastal fringe.
