Current ASCAT (satellite wind speed) pass shows a low in the Northern Tasman with SE gales proximate to the NSW Coast and a long, broad fetch of E’ly gales extending from the Tasman out to a position north of the North Island.
A large W/SW groundswell is due tomorrow but with onshore winds across the Mid Coast. Improving winds and another large SW groundswell is due later week.
A strong increase in groundswell due later week will be met by onshore winds, improving slowly on the weekend while easing in size.
A new S/SW groundswell is due later tomorrow, easing rapidly Sunday under northerly winds.
Late this week we may see another strong high move into the Tasman with a SE surge building up the coast and building swells Fri into the weekend, possibily getting sizey if a low pressure trough forms off the CQ coast.
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.
If anything that eastwards movement looks slower than modelled on Wed so large surf will persist at elevated levels for longer.
The weekend is a write-off with improving surf across metro locations early week, better across the South West from Wednesday onwards.
If anything that eastwards movement looks slower than modelled on Wed so large surf will persist at elevated levels for longer.
