This weekend and next week (Oct 13 – 19)

This afternoon's late kick in S'ly groundswell should peak overnight, but ease back from a good 3ft to possibly 4ft at south swell magnets at dawn tomorrow, smaller into the afternoon with a N/NW tending fresh NE breeze.

A small new S'ly groundswell should also be in the mix to 2ft on Sunday, generated by a polar front that's developed in our swell window today.

We then look at our prolonged NE swell event from Sunday through most of next week, owing to a strong and slow moving high in the Tasman Sea, squeezed by a slow moving mid-latitude low forming in the Bight and pushing east most of next week.

This will project a persistent fetch of strong and broad NE winds through our swell window from Sunday through Thursday, but strongest Monday and Tuesday when the mid-latitude low is strongest.

We'll see building levels of NE windswell through Sunday, becoming stronger mid-period energy on Monday with sets pushing towards 4-5ft at north-east facing beaches, with a peak likely Tuesday morning to 4-6ft.

The fetch will only slowly weaken through the end of the week, and as a result so will the swell ahead of a NW change on Friday.

Winds through this period will generally be onshore and out of the N/NE, possibly more N'ly early Tuesday and W/NW Thursday morning if we're lucky. Check back here on Monday though for the timing of the peak in swell and local winds.

Have a great weekend!
