The sheer longevity of the wind field maintain a rideable signal of surf for most days this week.

A stronger high at at even more Southerly latitude is South-west of Tasmania and tracking into the lower Tasman to replace the current high cell. This will reinforce the SE’ly fetch and maintain a weak onshore flow on the coast.

The current high cell in the Tasman has a trough of low pressure perched atop it, maintaining an E’ly fetch at a southerly latitude- roughly due East of Sydney.

Into the middle of next week and a robust fetch of E’ly winds extending out from Tasmania into the Tasman Sea, generated by the large high will maintain a solid level of E’ly swell.
