Western Australia Surf Forecast by Craig Brokensha (issued Monday 17th October)

Best Days: Tuesday, early Wednesday Perth, Friday, Saturday morning South West

Recap

Large stormy waves across the state Saturday, easing into Sunday and becoming much cleaner with an offshore around Perth and S/SE winds in Margs. Perth saw clean fun 2ft+ waves, with peaky 8ft+ waves across the South West.

Today onshore winds kicked in again across the South West, while Perth was a little mixed with tiny leftovers.

This week (Oct 18 - 21)

Our large and powerful S/SW groundswell due tomorrow across the state is still on track, with satellite observations confirming severe-gale to storm-force W/SW winds generated in our swell window over the weekend.

The storm generating this swell is currently clipping the south of the state but moving off quickly to the east.

This is the best result as we'll see large consistent waves tomorrow with light offshore winds as a high pressure system quickly moves in from the west.

The South West is expected to peak around 10-12ft, while Perth should offer 2ft to occasionally 3ft sets with light offshore E/SE winds across all regions. The afternoon should remain clean in the South West with a variable or weak SW sea breeze, with fresher S/SW winds around Perth.

Another front moving in on Wednesday will bring onshore winds again across Margs, with an early S/SE breeze up in Perth but fading 1-2ft sets.

No major swell is due off this front, with a weak mid-period S/SW swell for Friday from a fetch of strong S/SW winds being projected towards us.

Margs is due to offer weak 4-6ft waves Friday morning, with 1-2ft sets around Perth, easing into the afternoon. Conditions will improve again with offshore E/SE breezes, ahead of afternoon sea breezes.

This weekend onwards (Oct 22 onwards)

Friday's mid-period S/SW swell will continue to ease through Saturday with offshore E/NE winds across the South West, favouring swell magnets. 3-4ft sets are due, with tiny waves in Perth.

Longer term some new SW groundswell is due Sunday ahead of a likely larger SW groundswell mid-next week. More on this Wednesday.
