Western Australia Surf Forecast by Craig Brokensha (issued Friday 20th November)

Best Days: Saturday morning, Sunday morning more so in the South West, Monday morning in the South West, protected spots Wednesday and Thursday morning

Recap

An improvement in conditions across all locations yesterday morning though still bumpy and not perfect in the South West with easing sets from 5-6ft, cleaner and to 2-3ft in Mandurah and 2ft across Perth.

Today we've got smaller surf with an early offshore across the South West but this has since gone onshore, fun and 2ft around Mandurah with 1-2ft sets in Perth.

This weekend and next week (Nov 21 - 27)

After easing the last couple of days across the state, we've got a fun new swell due tomorrow and with favourable morning winds.

A relatively weak but still decent frontal system firing up north-east of Heard Island this week has generated a fun mid-period W/SW swell that should peak tomorrow to 5-6ft across the South West, with smaller 1-2ft waves to the north.

Winds should be light SE across the South West tomorrow morning ahead of afternoon sea breezes, S/SE further to the north in Mandurah and Perth.

Come Sunday a secondary smaller pulse of swell should keep the magnets in the South West around 4-5ft with a light morning E/SE offshore, 1-1.5ft further north and with a morning SE breeze.

Monday should be clean again but the swell smaller and only suitable for the South West swell magnets.

A low point in swell is expected Tuesday but then we look at the large SW groundswell due into the middle of the week.

Similar to earlier this week, a surface trough drifting in from the southern Indian Ocean is expected to deepen into a strong low south-west of us, generating a fetch of severe-gale W/SW winds in our western and then south-western swell windows as it tracks east.

A large, long-period swell is on the cards, coming in around 8-10ft at this stage in the South West, 3ft in Mandurah and 2-3ft across Perth but with strong S/SE-S winds. GFS has the storm a little stronger and the swell larger, but we'll review this Monday.

Winds for Thursday are up in the air as GFS pushes a secondary front into us, but more on this Monday. Have a great weekend!
