With no new swell sources on the cards, we’ll have to make the most of what’s on offer early Saturday morning.
So moving on to the specifics: today’s south swell is expected to throttle down as we move through Thursday.
We’ve got a windy period ahead for the entire SE region of Australia in conjunction with a major cold outbreak. In fact, apart from a temporary easing trend later this week (sometime around Thurs), a renewal of strong fronts will bring about further windy conditions from Friday right thru’ the weekend.
During Saturday afternoon, a new pulse of small, long period S/SE groundswell is expected to reach the South Coast, generated by a small polar low that developed right on the tail end of the frontal passage that is responsible for the current south swell.
A series of strong fronts have been powering through the lower Tasman Sea over the last day or two and although not very well aligned for the East Coast, are generating a series of southerly groundswells that’ll impact the region for the short term.
So, the synoptic situation is as such: the Tasman Low responsible for our current swell is tracking towards New Zealand post-haste, and its swell source has long been shut off inside our swell window. So a rapid easing trend is expected into tomorrow.
The new E/SE swell currently building across the region will peak overnight and trend downwards steadily through Saturday.
Looking like a good finish to the week.
A complex, deep trough currently lies off the west coast of New Zealand, and it's expected to be an active source of swell for the entire NSW coastline for the rest of the forecast period.
The current building short range south swell should hang around into Saturday morning, before easing a little throughout the day. Of more interest is the likelihood that local winds will throttle back after lunch, and possibly swing to the SW during the afternoon, courtesy of a small low forming east of Bass Strait, deep within a broad trough stretching right along the East Coast.
