Following that we’ve got a spring like week ahead with only some minor NE windswell to offer up some rideable waves.

Friday, 19 July 2024

Much stronger S swell signal for Sunday. A trough of low pressure and front rapidly push into the Tasman. Gales will be short-lived but sufficient to whip up a spike in S swell.

Wednesday, 17 July 2024

This is driving stiff W’ly tending SW’ly winds all the way up to the tropics - even New Caledonia is seeing this stiff SW flow! The current northwards moving low and proximate fetch will generate a quick spike in S swell before it quickly moves away with following fronts now looking more zonal and not as favourable for swell production. 

Monday, 15 July 2024

We have a deep low (985hPa) adjacent to Tasmania and another attached low centre further E in the Tasman with the long E/NE infeed into this complex low gyre focussed near the west coast of the North Island and slowly sliding out of the swell window.

Friday, 12 July 2024

The circulation in the trough line has increased wind speeds in the fetch as the air mass moves from high to low pressure. As a result we’ll see an increase in wave heights and period through tomorrow.

Wednesday, 10 July 2024

A trough is currently clearing the coast, expected to anchor a broad E’ly fetch generated by a monster high straddling New Zealand. This anchored trough fetch, or trough block pattern is favourable for swell production for almost the entire Eastern Seaboard and will come with mostly offshore winds until the weekend brings a more S’ly biased flow to temperate NSW.

Monday, 8 July 2024

An inland trough eventually clears the coast later Tues or Wed and the broad E’ly infeed into the trough transforms a typical but out of season tradewind fetch into a more broadscale “trough block” feature which will send swell to most of the Eastern Seaboard.

Friday, 5 July 2024

The “trough block” pattern mentioned on Wed looks to set-up as the clearing trough Mon sets up a long N-S oriented line in the Tasman to Coral Seas and focusses a long E’ly fetch through this vast area. Windspeeds are the limiting factor but we should see a steady increase in E-E/NE swell from Thurs into next weekend.

Wednesday, 3 July 2024

A low in the Tasman is moving north with a slingshot fetch of S-SE winds expected to rebuild wave heights from the S-SE later today and into tomorrow while a trough of low pressure in the Coral Sea is sending more E’ly angled swell into the sub-tropical Points. The combination of low and high pressure is maintain a firm ridge along the eastern seaboard with plenty of S-SE wind. 

Monday, 1 July 2024

Although the constant S-SE winds will be problematic there’ll be heaps of swell as low pressure remains in the Tasman, with a slingshot fetch expected as the low moves N during the week.
