Fun waves from Friday with offshore winds and smaller swells
Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 19th October)
Best Days: Friday morning both coasts, Saturday, Sunday and Monday mornings in the South West, Wednesday both coasts
Recap
Large pumping waves across the South West yesterday with 10-12ft+ of clean S/SW groundswell, while Perth and Mandurah built to 2-3ft before sea breezes kicked in.
Today the swell was half the size and onshore in the South West with cleaner 2ft sets left further north.
This week and weekend (Oct 20 - 23)
Tomorrow will be a touch smaller again than today but fresh to strong S/SE winds will create average conditions with not enough size for protected spots.
Friday morning is still looking fun with a new mid-period S/SW swell from a relatively weak front pushing up and past us tomorrow.
Exposed breaks in the South West should come in around 4-5ft+ with 1-1.5ft waves around Perth (1-2ft Mandurah). A ridge of high pressure moving in Thursday evening will see winds swing offshore from the E, variable into the afternoon across the South West, with S/SW sea breezes further north.
Saturday morning will be clean as well but small with the swell easing from 3-4ft, tiny to the north. A fresh E/NE tending variable wind will favour swell magnets.
The swell is due to bottom out early Sunday morning and an early offshore wind will again favour magnets but the surf will hardly be 2-3ft.
Into the afternoon a fun new SW groundswell is due, produced by a broad fetch of pre-frontal W/NW gales through our swell window over the coming days.
While not ideally aligned, we should still see fun 4-5ft waves developing across the South West into the afternoon, 1-1.5ft around Perth later, easing from a similar size Monday morning.
Afternoon sea breezes will create average conditions Sunday, but we should see clean waves again Monday morning with a SE breeze, we'll confirm this Friday.
Next week onwards (Oct 24 onwards)
Another large and powerful SW groundswell is due across the state mid-next week, produced by an intense polar low firing up south-west of us. A fetch of severe-gale to storm-force W/SW winds will be aimed through our swell window, producing a long-period swell that at this stage will come in around 8-10ft, with 2ft+ waves in Perth. Conditions are looking clean, but we'll confirm this Friday.
