Western Australia Surf Forecast by Craig Brokensha (issued Monday 3rd November)

Best Days: Tuesday morning, Wednesday morning south of Perth, dawn Thursday, Saturday from Perth north, Sunday morning


Conditions were clean and good across exposed spots across the state Saturday morning with small fading 1-2ft waves in Perth and 3ft waves up at Gero. Sunday was poor with tiny amounts of swell and onshore winds leaving no options for a decent wave.

Today started off slow and onshore, but a good new W/SW swell has since built across the South West and will show in Perth this afternoon and Gero later. Conditions will remain poor though, but tomorrow will be a different story.

This week (Nov 4 - 7)

This afternoon's kick in W/SW groundswell will be replaced by a stronger and better increase tomorrow, peaking through the day to 6-8ft at exposed spots in the South West, reaching 2-3ft in Perth from mid-late morning and building to 4-5ft+ up at Gero.

Winds will be good and light offshore from the East in the South West, E/SE around Perth and SE up at Gero before sea breezes kick in.

As the swell eases Wednesday winds won't be as favourable around Perth and Gero, with a touch more south in them, but Margs should be nice again with a straight E'ly offshore.

Our secondary longer-range pulse of W/SW groundswell for Friday is still on the cards, but a close-range and larger W/SW swell is due to fill in at the same time, but this will bring with it fresh to strong onshore winds.

The close-range swell will be generated by an intense mid-latitude low pushing up and into us, aiming a fetch of gale to severe-gale W/SW winds right into the south-west of the state.

A large W/SW swell will result, coming in at 10ft+ in the South West, 3ft+ in Perth and 6ft+ later in the day Friday up at Gero, holding a similar size Saturday morning.

Now winds will be poor and strengthening from the W/NW Thursday with fresh to strong but easing SW tending W/SW winds into Friday leaving no real decent surfing options.

This weekend onwards (Nov 8 onwards)

Friday's large swell will back off into Saturday but we should see a secondary reinforcing W/SW swell through the day, slowing the easing trend before wave heights continue to drop through Sunday and Monday.

Winds unfortunately look to linger onshore into Saturday in the South West, but further north around Perth and Gero, morning offshores should be seen. Sunday is likely to be better with SE winds across most locations with E/NE winds Monday, but we'll review this Wednesday.

Longer term there's nothing significant until Wednesday next week when we may see another intense mid-latitude low generate a large stormy swell, but we'll have another look at this Wednesday.
