A front and small low are now racing across the Tasman with a high over NSW moving into the Tasman and directing a freshening N’ly flow across most of the Eastern Seaboard. So far, so spring. A complex low, front and trough then approaches from the W, bringing a flush of W’ly winds and a S swell.

A rapidly deepening low will move in from the west late week, bringing a solid spike in swell but with strong onshore winds, improving Saturday as it eases steadily.

A small W/SW swell will peak with sea breezes tomorrow, with a stormy S'ly swell for the weekend.

All the current swell will go to waste, not cleaning up until very late Wednesday but more so Thursday while easing.
