Weak high pressure in the Tasman and a trough is creating a “doldrums” type pattern of slack pressure gradients and small swells this week, with a few wind changes to negotiate. No major swells expected this week. The headline feature is a potential major tropical cyclone drifting into the Coral Sea with a poleward (southwards) track late this week, over the weekend and into next week.

Low pressure has moved off the coast and is slow moving, with a broad fetch of strong E’ly winds on the southern flank of the low supplying plenty of E-E/SE swell to Southern NSW (and Tasmania).

A dynamic weather event is underway as a complex inland low approaches the Far South Coast of NSW, expected to enter the Tasman Sea tomorrow. A moist NE-E/NE infeed into the low is generating plenty of rain (heaviest falls on the South Coast) and building swells from the same direction.

Another dynamic week ahead with a complex trough expected to form a surface low off the NSW South Coast mid week, details below.

Not a great deal of action likely this weekend. High pressure is straddling Tasmania with the remnants of a front lingering near New Zealand with an off-axis fetch. A coastal trough and an inland trough maintain unstable conditions with a developing N-NE flow over the weekend.

It’s a weak synoptic pattern with no major swell sources- a passing front weakens as it traverses the Tasman, leaving an off-axis fetch parallel with New Zealand. There should be enough minor swell sources of no real quality to stay wet through the short term.

The troughy pattern remains installed into the medium term so we’re still keeping an eye out for short range features which could supply local swell sources.

Strong, long period S’ly groundswell should be peaking Mon morning, before an easing trend through the day.

Another powerful low tracking into the Far Southern Tasman- this time at potential storm force- sends more uncommonly long period S swell up the NSW Coast (although better aimed up the Tasman Sea pipe towards Fiji). With swell periods potentially in the 19-20 second band there’ll be some real juice in the swell.
