Typical Spring pattern with a slight La Niña/IOD twist unfolding at present. A large high is now moving into the Tasman, directing a N’ly flow along most of the Eastern seaboard. That flow intensifies in response to an approaching series of troughs and a complex low in the Bight.

Make the most of today on the beaches ahead of some small, inconsistent westerly swell into Friday afternoon, better Saturday.

We've got large but steadily easing surf tomorrow with no decent swell to follow up until next week.

A strong, but decaying cold front tied to a mid-latitude low is pushing gales through a wide swathe of the lower Tasman, with a handy S swell now being generated for the region. A relatively weak high (1025hPa) is pushing though the Bight with a transitory ridge, quickly breaking down and tending N’ly mid week , before another mid-latitude low pushes through and brings a NW to W’ly flow across the weekend.
