Strong fronts have already transited the Tasman Sea with some long period S-SSE swell pulses incoming. Those pulses will be concurrent in a more dominant building E/NE-NE windswell episode, through the rest of the week and into the weekend. Lots of action next week as both our Eastern and near Southern swell windows fire up.

Plenty of size for the Mid Coast on the weekend with workable conditions Saturday, options on the South Coast over the period.

A much stronger high is moving into the classic La Niña slot- SE of Tasmania- where it will start to be squeezed by another approaching inland trough and complex low pressure system. That will see increasing NE winds come into play from mid-week with increasing levels of NE windswell.

Make the most of today across Margs before onshore winds kick in tomorrow afternoon and write-off the surf until later week.
