The long, elongated trough line extending off the NSW Coast and angling in a NW/SE orientation towards New Zealand is now located a bit further north than modelled on Wed.

Wednesday, 24 November 2021

Lots of S quarter swell and wind from the same direction this weekend. With the trough extending out from the NSW South Coast towards the South Island, and a long fetch of S/SSE gales developing through the lower Tasman,  there’ll be no shortage of size.

Monday, 22 November 2021

Our current unstable, stormy pattern is being driven by a peanut-shaped high straddling Tasmania, and multiple troughs of low pressure, stretching from the interior of NSW, out to the Mid North Coast and South Pacific near New Zealand’s North Island.

Friday, 19 November 2021

The pattern as we described it on Wed remains fundamentally the same, but the position of the moving parts has shifted so there’s some significant changes to the weekend f/cast.

Wednesday, 17 November 2021

Weak fronts are below the country and an inland low is tracking across from WA, tied to the continuing pattern of interior troughiness which is associated with a developing La Nina pattern. This pattern, which has been with us for most of the last few weeks, is expected to see continuing small, flukey swells into the medium term.

Monday, 15 November 2021

A deep mid-latitude low with high pressure support in the Bight and multiple cold fronts has now moved E of Tasmania with W to SW gales pushing out of Bass Strait and a deeper SSW fetch pushing up from the Southern Ocean into the Tasman Sea. It’s a wintry looking system and it has a nice sting in the tail as a small troughy intensification slingshots up into the Tasman Sea through tomorrow, giving another longer period pulse S swell to add onto the main body of the swell.

Sunday gets a little upgrade, in energy at least. A coast hugging fetch of gales whips past the NSW South Coast overnight Sat, into the early hours of Sun, before the low moves away rapidly during the day.

Wednesday, 10 November 2021

The troughy pattern will see multiple wind changes through to the end of the week with some flukey swells on offer before the inland low enters the Tasman this weekend and supplies a slightly larger S swell.

Monday, 8 November 2021

Pressure gradients are weak across our main swell windows and through the region as an interior trough drifts NE and a weak, troughy area extends out into the Tasman sea, without creating much of a squeeze on a weak high pressure centre over New Zealand.

Friday, 5 November 2021

The fetch out of Cook Strait, extending up past Taranaki Peninsula and into the Tasman sea looked good on ASCAT (satellite windspeed) passes through Wed/Thurs, with areas of storm force winds embedded in a long fetch of severe gales to low end gales. With the buoys and observations already confirming the swell it’s only local winds we’ll be concerned with this weekend.
