High pressure over the continent its still ridging along it’s Southern flank with a westerly belt creating flat, groomed conditions. A deep, compact  low is well SW of Tasmania, weakening as it enters the lower Tasman. A decaying front linked to the low spawns a broad area of low pressure in the Tasman tomorrow and then lingers in the Tasman for most of the week.

OK, the continent is covered in high pressure, now drifting out over NSW into the Tasman and right across our wide swell window we’ve got very placid sea states leading to a continuation of small, weak surf.

We’re midway through a pretty sleepy week, swell-wise. A high pressure cell is drifting across the interior of the continent with a trough/front connected to a high riding low pushing East of Tasmania through today. Thats’ driving a mod/fresh synoptic W’ly flow across most of NSW and extending up into the sub-tropics.

The coming week is slow with nothing of note. Later next week holds better potential.

That will supply groomed conditions for a small but fun E/SE swell signal coming off the top of the North Island ( better aimed at targets to the North)

Wednesday, 7 June 2023

The evolution of the current pattern has sped up compared to Monday’s notes with high pressure drifting towards the South Island and weakening and a low centred around the North Island moving NE. A fetch off the top of the North Island is just scraping the edge of our swell window (better aimed at the sub-tropics).

After a much more settled, stable May the first week of June is looking like a temporary back-slide into a more La Niña-esque pattern. A huge (1035hPa) high is sitting E of Tasmania with a low pressure system straddling New Zealand. The high is directing moist onshore winds right up the Eastern Seaboard, while the low has several swell producing fetches associated with it, albeit nothing too major.

Friday, 2 June 2023

A front pushing aggressively NE into the lower Tasman on the weekend forms a low pressure centre which becomes slow moving near New Zealand early next week and this will be a co-main swell source for the week. The other source will be short range, peaky E’ly swell from a tradewind style fetch in the Southern Coral Sea.

Wednesday, 31 May 2023

No great change to the current pattern with a large high sitting very far up (right up on the QLD/NSW border!) allowing free passage for cold fronts into the lower Tasman and a generally synoptic W’ly flow to continue across the region. Mostly long period S swell trains will continue to the be the dominant swell source until next week when a much more S’ly located high brings an onshore flow to most of the Eastern Seaboard. A trough of low pressure looks to briefly form off the Mid North Coast early next week before moving away quickly.

Very wintry looking synoptic chart as we exit Autumn with a large high moving in over the continent with active cold fronts tied to low pressure systems tracking into the Tasman Sea. That pattern will extend through most of the week before a high cell drops into the Tasman Friday, with stronger frontal activity expected over the weekend and into next week
