Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 9th Novemeber)

Best Days: Margs Sunday morning, all coasts Monday morning


Excellent waves across all coasts yesterday with clean 5-6ft surf in the South West, 2-3ft waves around Mandurah and 1-2ft surf in Perth.

Today the swell has dropped back a touch and the South West was the pick with morning offshores, but these have since shifted back to the SW.

This week and weekend (Nov 10 - 13)

The next few days are terrible for our region with onshore NW winds ahead of a front tomorrow, swinging SW through the day, while Friday will see lingering W/SW-SW winds.

Surf wise background SW swell energy should keep 3-5ft sets hitting Margs, tiny to 1ft around Perth, persisting at a similar size Saturday. S/SW winds unfortunately look to linger into Saturday as well, finally swinging offshore Sunday morning from the E/SE.

Our new SW groundswell due for Sunday is still on track, but the timing has been pushed back a touch.

The frontal system generating it will be a touch weaker, resulting in the slightly later arrival, but we should still see Margs kicking to 5-6ft late afternoon, with maybe 1-2ft sets on dark around Perth.

Unfortunately sea breezes will be in by then creating bumpy conditions.

Next week onwards (Nov 14 onwards)

Sunday's swell should ease back through Monday with clean conditions again under a light offshore wind. Margs should still be around 4-5ft with 1-2ft sets in Perth.

Come Tuesday onshore winds are due to kick back again as a broad but not overly strong mid-latitude low pushes up and into us early next week.

A large mid-period W/SW swell is expected off this low Wednesday and Thursday but with onshore W'ly winds.

There doesn't seem to be any let up of the onshore winds into the end of the week or following weekend with weak fronts due to keep peppering the country, but more on this Friday.
