A couple of clean mornings but small surf, onshore through the end of the week before improving slowly on the weekend.

Through the early part of this week the low slips SE of Tas and a complex, troughy pattern with multiple low centres sits in the Tasman. This complex low pressure area eventually gets squeezed by an oncoming high generating fresh S’lies and which overlap with deeper S’ly fetches to create a series of S swells later this week.

The surf will continue to build in size tomorrow but with generally poor conditions, only improving from Friday but best Saturday.

By Sunday an approaching cut-off low and high in the Tasman drive a straight onshore E to NE flow onto the East Coast.
