Recap

Yesterday was a choppy mess across all locations as the secondary swell generating front moved in and across us, bringing strong onshore winds.

Today we’ve got easing surf with cleaner conditions under variable offshore winds, 2-3ft in Perth and Mandurah with 8ft sets still pushing through Margs.

This weekend and next week (Aug 3 - 9)

These notes will be brief today as Steve covers the Olympic surfing event.

The weekend ahead will see easing levels of swell with clean conditions each morning, favouring the South West as the swell declines.

Perth and Mandurah look to be around 1-2ft tomorrow with 4-6ft sets in the South West under a morning E/NE breeze, variable onshore into the afternoon, smaller Sunday along with E/NE tending N/NW winds.

Monday will be a lay day with small surf and strengthening NW tending N/NW winds ahead of a large, long-period W/SW groundswell on Tuesday.

The source of this swell is a strong low that’s formed to the east of South Africa, with a great fetch of severe-gale to storm-force W/SW winds pushing east towards us. The storm will weaken on approach, taking off a bit of size, but we should see the South West kicking to 10-12ft into the afternoon, 3-4ft across Mandurah and 3ft across Perth.

Unfortunately the remnants of the storm will clip us on Tuesday bringing strong N/NW tending NW winds (N/NE early Perth and Mandurah), with stronger NW tending W winds into Wednesday.

These stronger winds will be associated with a slow moving, trailing frontal progression pushing in slowly towards us next week.

Besides bringing onshore winds, it’ll generate reinforcing levels of oversized swell but with less period through Thursday along with persistent W/NW winds, fresh to strong in nature.

Perth and Mandurah are likely to see variable winds Friday as the swell eases but we’ll review this on Monday.

Longer term there’s plenty more large swell generating systems on the way but with tricky winds. Have a great weekend!
