Western Australia Surf Forecast by Craig Brokensha (issued Monday 12th October)

Best Days: Tuesday morning, Friday morning, Saturday morning, Sunday, Monday morning

Recap

A solid kick in long-period SW groundswell seen across the South West late Friday, held in better than expected on Saturday with 4-6ft sets across exposed breaks but with a dicey and light S/SW breeze. Perth was around 1-2ft and clean early before the onshore change moved through.

Sunday saw cleaner conditions across both coasts but smaller 3-4ft+ surf around Margs and 0.5-1ft sets around Perth. Today similar waves are continuing across both coasts with favourable offshore winds through the morning.

This week (Aug 13 - 16)

Our small kick in W/SW groundswell for tomorrow ahead of the better but less consistent W/SW groundswell later Wednesday and Thursday morning are still on track.

Tomorrow morning will be the cleanest and best with early light offshore winds, freshening from the W/NW into the afternoon. Size wise, Margs should see inconsistent 4-5ft+ waves across swell magnets, with 1-1.5ft sets around Perth.

Into Wednesday some close-range energy is due from a front currently to our south-west, more in the 4-6ft range across the South West and 1-2ft in Perth ahead of the larger groundswell kick later in the day.

This groundswell was generated late last week and into the weekend by a vigorous and slow moving polar low to the south-southeast of South Africa.

The swell should kick later in the day but peak Thursday morning to 6-8ft across the South West, with the chance of the odd bigger cleanup, with 2ft sets around Perth.

Unfortunately conditions Wednesday and Thursday will be poor with a fresh W/SW breeze on the former, and SW winds on the later.

Come Friday winds will back off, and swing SE around Perth, with Margs likely to see variable breezes but lumpy and uneven conditions.

Very late in the day a new SW groundswell may be seen, but this will be more likely on Saturday morning.

This weekend onwards (Oct 17 onwards)

Late Friday's possible swell will be generated by a strengthening low late in our swell window to our south-west on Thursday. A fetch of W/SW gales will be generated through our swell window, with a pulse Saturday morning to 4-6ft due, with Perth likely not too see much size above 1ft to maybe 2ft.

Winds are looking decent early with light offshore breezes ahead of an afternoon S/SW'ly.

Another larger increase in SW swell is then due Sunday afternoon, fading Monday, as a secondary stronger low forms earlier and further north in our swell window on Friday.

This swell should reach an easy 6-8ft+ across exposed breaks Sunday afternoon in the South West with 2ft sets in Perth with favourable morning offshores ahead of S/SW sea breezes.

Longer term, further and larger (in scope) polar frontal activity is expected in our swell window into next week, generating plenty of SW swell for the middle to end of the week, but we'll have another look at this on Wednesday.
