Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 25th March)

Best Days: Exposed breaks Thursday and Friday mornings, Sunday morning, Monday morning


Small, clean easing S/SW swell from the 3ft to occasionally 4ft range across Margs with tiny waves around Perth and fun small surf up at Gero.

Today the swell has steadied ahead of a new S/SW swell due this afternoon with clean 3ft waves around Margs again, 0.5-1ft sets in Perth and clean 2ft waves up at Gero.

This week (Mar 26 - 27)

This afternoon's kick in S/SW groundswell should build to 3-5ft late across the South West and winds should remain favourable and offshore, so keep an eye on the cams and local obs for a late session.

This swell should ease through tomorrow from 3-4ft in the South West, 1ft around Perth and 2-3ft up at Gero under favourable E/NE breezes that will likely tend NE and then variable ahead of afternoon sea breezes.

Friday will become small right across the state with early E/NE tending NE winds ahead of weak variable NW sea breezes.

This weekend onwards (Mar 28 onwards)

A very slight kick in small SW groundswell is due in the South West to 3ft or so midday Saturday, with no real change in size due north. Winds are also due to be less than favourable for exposed breaks with a SE'ly around Margs.

Sunday/Monday's swell is looking much better, with a couple of strong polar fronts due to fire up in our south-western swell window from today.

An initial broad fetch of W/SW gales will set in motion an active sea state for a secondary system to piggy back over on top of, generating a moderate to large sized SW groundswell, due to build through Sunday, peaking through the afternoon in the South West and Perth, easing into Monday (peaking in Gero early).

Margs should build to 6ft+ through the afternoon with 2ft sets in Perth and 3ft+ waves late in Gero, peaking Monday morning to 3-4ft+.

Winds look good Sunday with morning offshores from the E/SE ahead of afternoon sea breezes and then Monday looks a little unsure but variable winds are more than likely before onshores kick in.

Tuesday should be smaller again, with a very long-period groundswell showing on the charts not having any real size attached to it with it being generated in our far swell window below South Africa. Margs should offer 3-5ft waves with 1ft+ sets in Perth and 2-3ft waves up at Gero.

A new moderate sized SW groundswell is due into Wednesday from a similar but much weaker frontal progression to the one generating Sunday's swell.

Smaller surf is due off this progression though, reaching 3-4ft+ into Wednesday evening in the South West, 1-1.5ft in Perth and not arriving until overnight up at Gero, easing from 2ft to maybe 3ft Thursday morning. We'll look into this closer on Friday though.
