• Moderate sized E/SE groundswell building later Fri, peaking Sat with W tending weak sea breezy winds

Recap

Saturday started small to tiny with yesterday seeing building levels of NE windswell but with unfavourable winds.

Today has come in cleaner but smaller and slower with stronger E/NE energy arriving from a strong low in the Tasman Sea.

This week and weekend (Oct 1 - 6)

The low in the Tasman has weakened but we’re still seeing a healthy fetch of strong E/NE winds being aimed towards us and this should produce an inconsistent but fun 2ft of E/NE swell through tomorrow and Wednesday, easing Thursday.

A gusty NW wind will give into a shallow S/SE change on Tuesday with SW tending NE winds on Wednesday.

As the E/NE swell fades, some new small S’ly swell is due to replace it, generated by a healthy frontal system moving up past us tomorrow evening.

No major size is due but we should see a small 2ft wave on the south magnets Wednesday, easing Thursday.

The front is due to spawn a low off New Zealand mid-late week and with this, a fetch of S/SE gales are expected to be aimed through our eastern swell window Thursday, easing slowly Friday.

We should see a great, moderate sized E/SE groundswell from this source, building Friday afternoon but peaking Saturday to a good 4ft+ or so along with a small to tiny N/NE windswell signal.

Winds are due to shift W’ly on Saturday morning ahead of weak sea breezes, with the swell easing Sunday from 3ft or so under strengthening NW winds.

Following this nothing too major is due besides some new S’ly swell mid-next week. More on this Wednesday.
