Welcome to Winter Part 2: Step-ladder S swells expected from mid-week, becoming very sizeable later in the weekend
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.
