This week and weekend (May 24 – 27)

Today's S'ly groundswell should of eased into this afternoon and will hit a low point tomorrow morning ahead of a secondary large long-period S'ly groundswell into the afternoon and Friday.

Currently a vigorous polar low is south-west of us, generating a fetch of severe-gale to storm-force W/SW winds just out of our swell window.

We'll see this system move east and into our swell window this afternoon and evening, projecting a fetch of storm-force SW winds up and into the Tasman Sea, with a trailing S/SE fetch of gales on its tail tomorrow afternoon.

This will generate one the of the largest swells in recent history for Fiji this coming Sunday/Monday, but we'll see large long-period S'ly groundswell spreading radially into us from tomorrow afternoon, kicking to an easy 6ft across south magnets, with Friday morning likely easing from 6ft to possibly 8ft.

The S/SE fetch should then generate some reinforcing S/SE swell as the S'ly energy fades Friday afternoon, with Saturday morning dropping from 4-5ft.

Now winds tomorrow look less than ideal with a W/SW tending SW-S/SW breeze, much better Friday for south magnets with a W/NW tending NW breeze. Saturday also looks great with a NW tending N/NE breeze.

Into Sunday the SE swell will be smaller and easing from 2ft to maybe 3ft, with offshore N/NW winds.

Longer term there's nothing too significant on the cards at this stage besides a small NE windswell. More on this Friday.
