Recap

No decent swell and onshore winds on the weekend, continuing into today.

This week and weekend (Sep 29 – Oct 4)

The coming period still looks poor for the South West up until the weekend at the earliest, with a few better windows to the north opening up before hand.

A flurry of not overly strong but persistent mid-latitude fronts are moving in from the west with fetches of strong W/SW-W/NW winds.

One of these systems started south-east of Madagascar on the weekend and this will bring the first pulse of mid-period W/SW swell for Wednesday across the state. Size wise there's no change to the outlook on Friday with sets to 6-8ft due across the South West, 2-3ft in Mandurah and 2ft+ across Perth.

Winds will be poor and strong from the W/NW tomorrow, weaker on Wednesday and tending more variable around Perth out of the E/NE.

It'll be lumpy but OK for the keen.

Into Thursday all locations will see winds swing back to the W/NW and strengthen as another mid-latitude clips the south of the state, bringing a small reinforcing SW swell for the afternoon and Friday morning.

Size wise it'll be below Wednesday's swell and conditions will be poor across all locations with strong S/SW winds as a high pressure ridge finally starts to move in behind the frontal activity.

The weekend looks much better for swell activity with a fun, mid-period S/SW swell on the cards for Saturday, generated by a more southerly located front at the base of the mid-latitude activity mid-late week.

A slow moving fetch of strong to gale-force SW-S/SW winds should produce a kick in size Saturday to 6-8ft across the South West, 2-3ft in Mandurah and a slower 2ft in Perth with the southerly swell direction.

Winds will take their time to improve though, with fresh to strong S'ly breezes across the South West, possibly tending S/SE at times, and better SE winds to the north.

Sunday is better as winds shift SE across a wider variety of locations and even possibly E/SE across the South West, but we'll go over this again on Wednesday. The swell will be on the ease though.

Into early next week we should see hopefully another pulse of fun S/SW groundswell across the South West and with more favourable winds. This swell doesn't look to be as big as Saturday's, but we'll have a closer look at this on Wednesday.
