A strong node of the Long Wave Trough is steering fronts into the Tasman Sea while a negative phase of the SAM (Southern Annular Mode) is bringing the southern Ocean storm track into a more northerly latitude, closer to the Australian continent and Tasman Sea. Both those factors will drive a series of strong cold fronts this week, with a step-ladder effect likely on swell pulses as each subsequent front works on an already charged sea state. 

Using today's results in Southern NSW as a proxy, we should see some solid south swell across Northern NSW on Saturday.

Fading energy into the weekend ahead of building levels of S'ly swell in size and period later next week and weekend.

Building surf with improving and strengthening offshore winds, tricky mid-late next week.
