Recap

A drop in localised windswell yesterday with cross-offshore winds, smaller today and effectively bottoming out with slightly better conditions.

This week and weekend (Feb 9 - 12)

We should see a small, inconsistent lift in mid-period SW swell through tomorrow, but not topping 3ft across the South West into the afternoon and with tiny waves to the north.

Early winds looks moderate to fresh out of the S/SE-SE, deteriorating and strengthening from the S/SW as the swell builds into the afternoon.

Unfortunately S/SE winds will meet the swell into Friday, with it coming in at a similar size to tomorrow afternoon, if not for the odd bigger one.

All in all it's not worth worrying about and that also applies to Saturday when the swell is expected to bottom out under fresh S/SE-SE morning winds. Also Tropical Cyclone Freddie isn't expected to generate any significant swell for us, with it being too tight in nature and moving away to the west.

We've got a couple of better swell producers on the cards from Sunday through next week as back to back polar lows fire up in the Heard Island region. The first developed yesterday and is now generating a weakening fetch of strong W/SW winds, and will project north-east towards us into the end of the week.

A fun mid-period SW swell is due from this source on Sunday, building to 4-6ft across the South West 2ft in Mandurah and 1-2ft across Perth before easing Monday.

Behind this low, a stronger system is forecast to fire up tomorrow morning, generating a better fetch of severe-gale W/SW winds, though weakening once east of a position drawn north-south of Heard Island.

This will result in a loss in size and consistency but we should still see good sized sets across the South West when the swell fills in Tuesday, building to a peak into the afternoon. Sets to 6ft to possibly 8ft are due into the afternoon with Mandurah building to 2ft+ and 2ft in Perth.

Lets, look at the local winds though, and the remnants of each low will bring average, dicey winds with Sunday performing best. An E/SE offshore is due through the morning ahead of strong S/SW sea breezes, gusty from the S/SE tending S/SW on Monday.

Tuesday unfortunately looks poor with winds due to strengthen from the W/SW as a small low pushes up and into us. This will bring some windswell contamination to the groundswell and winds look to linger out of the SW Wednesday, shifting W through the day.

The W'ly winds unfortunately don't look to let up at all through next week and weekend as we see strengthening mid-latitude fronts pushing up and clipping us.

This will bring plenty more swell from next weekend but with average conditions. More on this Friday.
