Recap

Windy conditions across the South West with surf to 4ft, increasing a little today with better though still strong SE winds. Sets to 4-5ft are breaking across exposed breaks and Mandurah has seen 1-2ft sets with tiny surf across Perth. The swell has kicked a bit more in size this morning in the South West with sets to 6ft across exposed breaks.

Better size sets late this AM

This week and weekend (Feb 1 - 5)

Today's new mid-period SW swell is due to peak this afternoon and ease over the coming days as winds improve and swing more east as a high slides in and under us.

Easing 4-5ft sets are due in the South West tomorrow morning, 1-2ft across Mandurah and 1-1.5ft in Perth along with strong E/SE-SE winds in the South West, easing a touch before shifting S/SE.

Friday will see gusty E/SE winds along with a new S/SW groundswell, generated by a strong polar low that's formed to our south. While late in formation, wind speeds around the low are gale to severe-gale (confirmed by satellite left) and this should produce an acute S/SW groundswell for Friday, peaking through the day to 4-5ft on selected south magnets, much smaller in protected spots.

Perth and Mandurah won't see any size at all.

This swell will fade into Saturday morning from 2-3ft as winds shift around to the E/NE, but another pulse of groundswell is due through the day (peaking afternoon), generated by a deepening extra-tropical low dropping south-east towards polar latitudes.

While not ideally aimed, a great fetch of severe-gale W/NW winds will generate a good pulse of reinforcing groundswell, kicking to 4-6ft on the south magnets through the afternoon as winds go sea breezey. Mandurah and Perth will again unfortunately miss out on any size.

A trough pushing in Sunday will come a day early, killing off options in the South West as the S/SW groundswell eases thanks to strong S/SE winds.

Easing surf with S/SE winds will create average to poor surf early next week with nothing really of note on the cards longer term. More on this Friday.
