The current winter-calibre storm exits to the SE over the next 24 hrs with a high pressure to the north maintaining a ridge with the W’ly flow which continues across the SW of the state. An elevated high pressure belt over the state and high in Madagascan longitudes maintains a NE track of storms from Heard Island to WA longitudes.

What follows will be an extended period of onshore winds and large surf, with embedded pulses in the 8-10ft range as the storm track is elevated and the SW of the state is in the W’ly flow.
Into next week and very active Indian Ocean storm track spawns a slow moving massive gyre with multiple (at least 3) back to back to back severe gale fetches which will generate L to XL surf, primarily benefitting the NW and Indonesia. SW WA will be mostly in the storm track and thus subject to a mostly stormy, onshore flow, with the breaks between onshore episodes unlikely to be sufficient for surf to clean up away from a few select winter spots.
Easing surf but with clean conditions across the South West tomorrow ahead of an extended run of XL onshore surf later next week.
All the current swell will go to waste, not cleaning up until very late Wednesday but more so Thursday while easing.
The weekend will be poor with an oversized, building swell, holding Monday morning but only going offshore mid-next week across Perth and Mandurah.
Clean conditions and fun sized surf are worth capitalising on in the South West ahead of a return to large, onshore swells.
A fun swell with cleaner conditions is due tomorrow, with a decent window of building swell and clean conditions Thursday. The weekend looks large and stormy.
We've got more favourable winds but weaker, smaller swells on the cards.
Tomorrow remains dicey for the South West, with clean but small waves into Friday/Saturday. A fun new swell is due Monday but that's it for the week.
