Western Australia Surf Forecast by Craig Brokensha (issued Friday 28th March)

Best Days: Monday morning, Tuesday onwards


Small clean waves have continued across the state the last few days, but a slight increase in swell was seen through yesterday and this has persisted into today to 3ft in the South West and Perth, with 1-1.5ft surf around Perth.

This weekend and Monday (Mar 29 - 31)

The weekend will start off poor with a small swell and onshore winds from the West as a strengthening mid-latitude low pushes in from the south-west.

This low is forecast to project a fetch of S/SW gales towards us, kicking up a large S/SW swell for Sunday but winds will be poor and fresh to strong from the W/SW tending lighter SW (as the low weakens).

Monday will see lighter onshore winds that will most likely tend variable in the South West, while Perth and Gero should see lighter offshores. The swell will be on a steady downwards trend though in the wake of the mid-latitude low, so get out during the morning for the best of it.

Next Tuesday onwards (Apr 1 onwards)

We'll head into a good period of waves for the South West and Gero into next week as a series of S/SW groundswells impact the state while at the same time a high pressure ridge sits to our south-west, resulting in generally favourable offshore winds.

This will be all related to the Long Wave Trough anchoring over the Bight and strengthening, aiming a series of strong polar fronts from out south-west up towards SA and Vicco (pictured above and below).

We'll see the side-band energy of these frontal systems in the form of medium to large pulses of S/SW groundswell with favourable winds.

The largest increases are due Friday and then the following Sunday under E/SE winds, creating excellent conditions for the Margaret River Pro. Size wise, we're looking at 6ft to occasionally 8ft sets at exposed spots, but we'll confirm this Monday.
