Western Australia Surf Forecast by Craig Brokensha (issued Friday 2nd November)

Best Days: Protected spots tomorrow morning, protected spots Tuesday morning, Wednesday

Recap

Onshore small surf yesterday across the South West with average conditions around Perth and surfable waves in Mandurah.

Today our large new SW groundswell has started filling in but with onshore winds across the South West, cleaner and 2-3ft up in Mandurah and 2ft around Perth.

We should see the swell reaching 6-8ft across the South West this afternoon but winds will remain average and onshore.

This weekend and next week (Nov 3 - 9)

The strong frontal system linked to todays large building SW groundswell is now moving off slowly through the Bight, out of our swell window and with this we'll see the swell dropping back through tomorrow.

Winds now look to take a little longer to swing offshore owing to the slow moving nature of the storm through the Bight and with this we'll see a less favourable S/SE wind across all locations tomorrow morning, possibly tending SE at times, and then back onshore S/SW from late morning.

Margs should ease back from 6ft+ (8ft cleanup sets on the exposed reefs), 2-3ft in Mandurah and 2ft in Perth, smaller Sunday.

Another cold front approaching from the south-west will unfortunately bring onshore winds to all locations on Sunday as the swell continues to fade.

This front however will be associated with a large powerful S/SW groundswell due Monday and Tuesday, with a very intense polar storm forming south-west of us this evening, generating a slow moving fetch of severe-gale to storm-force W/SW-SW winds through our southern swell window.

We'll see a cold front spawning off the back of the progression pushing up and into us Sunday and Monday, bringing an additional mid-period S/SW swell to the mix.

The groundswell is expected to build Monday and peak into the afternoon around the 10ft range on the sets across the South West, 3ft in Mandurah and 2-3ft in Perth.

Winds will be poor however and strong onshore from the S/SW owing to the front pushing up and into us.

Better S/SE winds (SE in Perth and Mandurah) are expected on Tuesday as the swell start to ease from 8-10ft, 3ft in Mandurah and 2-3ft Perth.

Wednesday finally looks clean and offshore across the South West with an E/NE offshore, variable into the afternoon.

There should still be a bit of size leftover and around 4-6ft across the South West, smaller and to 2ft in Mandurah and 1-2ft Perth.

Longer term it looks smaller but fun with winds from the SE to end off the week and into the weekend, but we'll have another look at this on Monday. Have a great weekend!
