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. 

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.

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.

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.
