Recap

Good fun waves across the South West and Mandurah yesterday morning with clean conditions and smaller surf, while today it's really backed off leaving small to tiny waves across the coast.

This weekend and next week (Oct 27 – Nov 2)

There's been no real change to the weekend's forecast, but the one thing worth pointing out, is that the jump in size shown through the morning is incorrect, with it combining some small long-period energy with the existing swell.

Size wise I'm only expecting a small 3ft to maybe 4ft wave on the magnets across the South West, tiny to the north, with a moderate to fresh S/SE wind, possibly tending SE for a period through the morning.

Into the afternoon and more so Sunday the most size should be seen, generated by a very slow moving polar low the last few days, generating a fetch of strong to gale-force W'ly winds.

The mid-period swell should provide good 4-6ft sets across the South West swell magnets, 1-2ft in Mandurah and 1-1.5ft Perth Sunday morning. Conditions look great with E/SE offshores expected across all locations before sea breezes kick in.

Later in the day Sunday and more so Monday morning a reinforcing SW groundswell is due from a pre and post-frontal fetch of W/NW and W/SW gales.

We should see a continuation of 4-6ft waves across the South West, 1-2ft in Mandurah and 1-1.5ft in Perth but a front clipping the state will bring onshore SW-W/SW winds to the South West, S-S/SE further north.

The front is expected to bring some new mid-period W/SW swell for Tuesday, swinging more SW in direction Wednesday and maintaining size.

This will be a result of a broad and elongated fetch of strong W/SW winds moving through our western and south-western swell window.

Size wise, the Margs region is only due to come in around 4-5ft+ again Tuesday, with 2ft sets in Mandurah through the afternoon (1-2ft Perth), easing from a similar size Wednesday.

Winds should improve on Tuesday, swinging SE, with great conditions Wednesday with a straight E'ly offshore.

Longer term there's a bit of action pegged for next weekend, but we'll have a closer look at this Monday. Have a great weekend!
