Recap

The large, pumping surf seen into the end of last week eased through the weekend and Saturday was cleanest and best before S'ly winds got into a new pulse of SW energy yesterday.

Today a new moderate-large SW swell has filled in but S'ly winds are only favouring protected spots.

This week and weekend (Nov 1 - 6)

Today's good pulse of new swell will peak this afternoon and ease back through the coming days as a high edges in from the west, swinging winds slowly more offshore.

Tomorrow morning will see S/SE winds across the South West, SE further north and with easing, fun sets from the 5-6ft range across the South West, 2ft in Mandurah and a less consistent 2ft in Perth

Wednesday looks smaller again but with more favourable E/SE winds across all locations before sea breezes kick in.

Later in the day Wednesday but more so Thursday morning a new pulse of SW groundswell is expected, generated by a strong but short-lived polar low firing up around the Heard Island region yesterday.

A fetch of severe-gale to storm-force W'ly winds were generated and behind this we'll see an additional fetch of NW gales tracking south-east, generating a secondary pulse of SW groundswell for Friday afternoon.

The first swell should peak around 6-8ft in the South West with 2ft+ waves in Mandurah and 2ft sets across Perth, with it arriving late Wednesday but peaking Thursday morning.

The swell will ease during the day and conditions look good with a gusty E/NE tending weaker NE breeze, light NW into the afternoon.

Friday will unfortunately see a trough move through, bringing SW winds to all locations, though it should clear quickly into the weekend, allowing winds to swing back to the SE-E/SE in the morning Saturday.

The secondary SW groundswell for Friday afternoon looks a little smaller than the first, coming in around 6ft in the South West, easing Saturday from a similar size, 2ft in Mandurah and 1-2ft across Perth.

As the swell continues to ease Sunday, conditions look less favourable in the morning with a S/SE breeze, with offshore winds due to kick back in Monday ahead of a trough and S/SW winds from Tuesday. Fun pulses of mid-period SW swell are due into next week, but we'll review this Wednesday.
