Western Australia Surf Forecast by Craig Brokensha (issued Wednesday April 12th)

Best Days: Margs Thursday morning, Margs Friday morning, Margs Saturday and further north into the afternoon, Margs Sunday morning (tiny Perth and Mandurah)

Features of the Forecast (tl;dr)

  • Fading surf into the end of the week with morning offshore winds
  • Fun, mid-period W/SW swell building Sat with moderate E tending weak S/SW winds, easing Sun with E'ly tending fresh SW winds
  • Small, mid-period SW swell Mon with fresh S/SE tending strong S/SE winds


Windy poor surf across the South West yesterday to 6-8ft, cleaner and peaky to the north to the 2ft range. All locations were cleaner today with a bit of lump left in the South West with easing 6ft+ sets, better to the north with clean 2ft waves in Mandurah, 1-2ft across Perth.

This week and weekend (Apr 13 - 18)

The source of the current swell left our window yesterday and as a result we'll see the size really dropping away through the day, small tomorrow with easing 3-4ft sets across Margs, tiny to the north.

Conditions will be nice for the magnets though with a light E'ly offshore ahead of sea breezes, similar Friday with an E/NE morning offshore.

Into the weekend a fun, mid-period W/SW swell should fill in Saturday, peaking into the afternoon, generated by a short-lived but small mid-latitude low today. A fetch of strong to gale-force W/SW winds should produce a kick in size to 4-5ft across the South West, 1-2ft in Mandurah and Perth late.

Winds look good in the morning and moderate out of the E, giving into weak sea breezes as the swell peaks, clean Sunday morning again as the swell eases.

There's still nothing major on the cards for next week as the storm track looks most active under the country and east of us.

Another mid-period SW swell is due Monday though with 3ft+ sets due across Margs but with less favourable S/SE tending strong S/SW winds as a trough moves through Sunday evening.

Tuesday should be clean again but on the small side.

Longer term there's the chance a stronger polar low will generate some better groundswell late week, but more on this Friday.
