We’ll see this pattern disrupted mid-week by an aggressive trough which brings S winds and swell before the next high slowly resets the trade pattern, this time further north in the Coral Sea.

Friday, 15 March 2024

Today’s onshore pattern will contract to the North Coast on Saturday, and Sunday looks very interesting with a new long period S/SE groundswell.

Wednesday, 13 March 2024

We’ve still got a broad trade wind flow in the Coral Sea, extending out into the South Pacific and anchored head and tail by low pressure along the monsoon trough. That’s producing heavy swells in the sub-tropics (full blown Point surf equivalent to cyclone swells) with a fair amount filtering down to temperate NSW. 

Monday, 11 March 2024

Lots of swell to look forward to this week, and winds should remain light under a weak local synoptic pattern.

Friday, 8 March 2024

There was a nice, lingering tail to the S swell event but we’re now entrenched in a classic late Summer pattern with strong high pressure moving into the Tasman, setting up a downstream blocking pattern and very healthy tradewind fetch through the Coral Sea, extending E into the South Pacific and south into the Northern Tasman.

Wednesday, 6 March 2024

Classic late Summer pattern next week with high pressure straddling New Zealand, a monsoon trough strung across Northern Australia extending into the South Pacific and a long, broad tradewind fetch between the two broadscale atmospheric features. The fetch is so broad and long that we’ll see quite an energetic E/NE swell propagate down the NSW Coast. 

Monday, 4 March 2024

We currently have a deep, winter-calibre double-headed low traversing the lower Tasman. Current ASCAT (satellite windspeed) passes show a long fetch of severe gales in the southern swell window and wave buoys are all in an aggressive upwards curve as strong S swells build along the Southern NSW Coastline.

Friday, 1 March 2024

Models are holding steady on a winter calibre low tracking well to the south- south-east of Tasmania during Sun and traversing the far Southern Tasman through Mon.

Wednesday, 28 February 2024

Some quiet days then follow before a much more robust front and low enter the lower Tasman late in the weekend driving some sizey S swell up the coast early next week.

Monday, 26 February 2024

We’ve got a weak, troughy pattern in the Tasman Sea, with a minor cold front passing to the SE of Tasmania and a new high pressure cell poised to enter the Tasman in it’s wake. The high cell is weak so we’re looking at a fairly uninspiring end to Summer, with some mid week NE windswell for Southern NSW and small background E swells for the sub-tropics.
