Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 4th December)

Best Days: Swell magnets in the South West tomorrow morning, Tuesday morning in the South West, Wednesday morning, Thursday morning in the South West

Recap

Fun waves across the South West magnets yesterday with an easing clean swell from the 4ft range, back to 3ft today. Locations to the north were tiny.

This week and weekend (Dec 5 - 8)

Small 3ft waves are expected to persist across the South West tomorrow with a background swell and conditions look favourable with a morning SE wind ahead of afternoon sea breezes. Perth and Mandurah will remain tiny.

A better E/NE offshore is expected on Friday morning but with no size left in the tank.

There's been no change to our mid-period W/SW swell for the weekend, either the onshore winds forecast.

A broad but relatively weak and slow moving storm north of Heard Island has generated this swell, with it expected to arrive early Saturday and peak to 4-5ft+ across the South West, 1-2ft in Mandurah and 1-1.5ft across Perth with NW tending stronger W/NW winds.

It now looks like a high moving in on Sunday will be a little delayed, resulting in average S/SW winds as the swell eases.

Monday will become cleaner with a SE offshore, but size wise, there's only a small fading 2-3ft wave expected.

Our new long-period W/SW groundswell for the middle of the week is still on track with a strong and distant storm taking shape directly south-east of South Africa.

A fetch of gale to severe-gale W/SW winds are being generated as the low moves slowly east, but it will weaken and break down north-west of the Heard Island region Friday evening, in our medium-far swell window.

This should produce an inconsistent long-period W/SW groundswell for us, though packing punch when the sets come compared to the recent swells.

We should see the fore-runners arriving Tuesday, building to 4-5ft later in the day and peaking Wednesday to an inconsistent 5-6ft across the South West, 1-2ft in Mandurah and Perth.

Winds Tuesday morning look favourable and E/SE, giving into afternoon sea breezes with great E/SE winds Wednesday when the swell peaks, offshore from the E/NE Thursday as it eases.

Following this there's nothing of significance so make the most of it!
