This week and weekend (Dec 9 - 15)

There isn't expected to be much left in the bank swell wise tomorrow morning.

Hit the magnets across the South West for a clean small and inconsistent wave. Conditions will be great with an E'ly offshore wind, tending variable ahead of late sea breezes.

Into the late afternoon and evening we should see a new long-range SW groundswell filling in, generated by a strong but distant polar low west of Heard Island earlier this week.

Sets should reach 3-5ft across magnets in the South West by dark with a peak Sunday morning to 4-5ft+. There'll be very long wait for the biggest and best sets though.

Perth and Mandurah aren't due to offer much over 1ft+ unfortunately.

Sunday's winds aren't great but OK with a morning SE offshore ahead of sea breezes.

The swell will fade through Sunday afternoon, back from a smaller 3ft max Monday morning with average S/SE winds.

The surf will hit a low point Tuesday with average S/SW winds, but a fun new mid-period W/SW swell is due Wednesday ahead of a stronger SW groundswell Thursday.

The mid-period swell will be produced by a weak mid-latitude front pushing north of Heard Island towards us, with fun 4-5ft sets due to develop across the South West, with building 1-1.5ft waves across Perth and Mandurah. Unfortunately winds look to remain average and from the S/SW tending SW as the front responsible for Thursday's swell pushes up from the south-west.

This front will be a touch broader and stronger while also projecting closer to us, generate a moderate sized SW groundswell for Thursday, coming in at 5-6ft across the South West and 1-2ft in Mandurah, 1-1.5ft Perth.

Better SE winds are also likely Thursday morning, but we'll have to review this again Monday. Have a great weekend!
