Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 22nd November)

Best Days: South West swell magnets Thursday, Sunday morning, Monday morning

Recap

Average conditions across the South West yesterday with a strong S-S/SW wind and building SW groundswell that reached 6-8ft through the day at exposed breaks. Mandurah saw 2-3ft sets, while Perth was 1-1.5ft early, building to a messy 2ft into the afternoon.

This morning was much better with straight offshore winds across all locations and great easing surf from 4-6ft in the South West, 2ft in Mandurah and 1-2ft in Perth.

This week and weekend (Nov 23 - 26)

Make the most of the current surf, as from here it's down, down, down.

Perth will become tiny tomorrow, while Mandurah may offer the odd small set, while Margs should be best with easing 3-4ft sets across magnets, smaller Friday and down to 2ft to maybe 3ft.

Conditions will be great again tomorrow and offshore with gusty E'ly winds, tending variable into the afternoon ahead of late sea breezes.

Friday is a little less favourable with S/SE winds across the South West, not ideal for magnets, while Perth and Mandurah will be cleaner but tiny.

The swell is expected to bottom out Saturday morning as fresh S/SE winds develop across all locations.

Our new SW groundswell for Sunday is still on track, with a strong polar frontal progression expected to form south-west of us tomorrow.

We should see a good fetch of W/SW tending SW gales projected through our south-west-southern swell window, followed by a secondary stronger front and fetch of W/SW gales in our southern swell window.

A moderate to large SW groundswell is due Sunday from the initial storm, with a reinforcing S/SW groundswell late Monday/Tuesday morning from the secondary front.

Then first swell for Sunday should build to a good 5-6ft+ across the South West through Sunday, with 2ft sets in Mandurah and 1-2ft waves in Perth.

The swell should then ease back slightly to 4-6ft, 1-1.5ft and 1ft+ respectively Monday, smaller Tuesday.

Winds on Sunday should improve, swinging more SE, and even E/SE across most locations, while Monday is a little unsure.

Longer term there's nothing significant on the cards, but more on this Friday.
