The Indian Ocean remains in a progressive pattern with a large high pressure belt and zonal disturbances in the Roaring 40’s supplying moderate overlapping SW pulses on a 24-36hr basis. Basically, overlapping swell pulses from these zonal storms will hold moderate surf all week, with subtle ups and downs.
Primary tabs
Into next week and offshore winds freshen into Mon as a new trough forms offshore from the Gascoyne and moves southwards.
Surf-wise a storm force system under Africa sends long period forerunners arriving Mon in the 19-20 second band before the bulk of the swell energy in the 16-17 second band fills in later Mon and Tues.
Into the weekend and a fetch tracking NE towards WA related to the decaying front brings a nice pulse of S/SW swell for the weekend.
Next week is looking subdued but with periods of mostly favourable winds. The gist of it is a band of blocking high pressure and a suppressed zonal storm track.

No great change to the short term outlook- a strong polar low flared up as it passes under WA and today with gales to severe gales well aimed at SW and southern WA.
A polar low flares up as it approaches a more southern point of the WA swell window Wed, with gales to severe gales expected.
Next week still looks iffy for winds as a node of the long wave trough steers fronts into the SW while slow moving high pressure sits in the Central Indian Ocean. Those fronts will maintain a moderate sized series of SW pulses from Tues.
Next week looks little more active now as a fetch of SW gales over the weekend between 70-100E builds seas to 20ft.
