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

Best Days: Saturday morning, Sunday morning, Monday morning, Tuesday and Wednesday mornings (Perth Saturday and Monday mornings)

Recap

Another morning of great surf across the South West yesterday with glassy clean 5-6ft sets ahead of afternoon sea breezes. Perth and Mandurah saw better 2ft sets at exposed breaks, easing back through the afternoon with weak sea breezes, leaving tiny surf into today.

Margs was still offering good 4-5ft sets this morning but with a more blustery offshore, favouring breaks closer to shore.

This week and early next week (Mar 10 - 16)

Tomorrow's a good lay day as the surf continues to ease and a weak change brings a freshening onshore breeze. Perth should see variable winds early but no size.

Friday and Saturday's moderate to large SW groundswell is still on track, with the vigorous polar low generating it now currently east of Heard Island while producing a fetch of gale to near severe-gale W/SW winds.

The low will project north-east towards the Bight over the coming day or so while weakening, leaving a strong SW groundswell in its wake.

The groundswell should fill in Friday afternoon and reach an easy 5-6ft+ by dark, ahead of a peak Saturday morning to 6-8ft, with 10ft bomb sets. Perth should see fun 2ft waves.

SE winds are due both Friday and Saturday mornings favouring slightly protected locations over more exposed breaks ahead of afternoon S/SW sea breezes.

Stronger SE winds will then kick in Sunday as the swell backs away. A new reinforcing SW groundswell should steady wave heights around 4-5ft+ through the day though across the South West, generated by a pre-frontal fetch of W/NW gales quickly sliding in behind the main swell producing system.

This will then be followed by a good post-frontal fetch of SW winds more in our swell window, producing another good SW groundswell pulse for Monday in the 5-6ft range, easing off through Tuesday and further Wednesday.

Conditions are looking nice and clean for this pulse Monday morning with an offshore E/SE breeze, with SE winds kicking back in again from Tuesday. More on this Friday.
