Western Australia Surf Forecast by Craig Brokensha (issued Friday 9th October)

Best Days: Saturday, Sunday protected spots, Monday protected spots, Tuesday, Wednesday morning protected spots in the South West

Recap

Not great at dawn across all locations yesterday morning but onshore winds eased and the swell kicked with fun 2-3ft waves across Perth, building to 3ft+ across Mandurah and kicking to 8ft in the South West after a very slow start.

Today conditions are much better across all locations with great, clean 2-3ft waves in Perth, 3-4ft across Mandurah while the South West has eased in size but with a lingering onshore wind.

This weekend and next week (Oct 10 - 16)

We’ve got a great run of swell and conditions due over the coming days, with back to back, large, long-period swells due to fill in.

The first swell is due to build tomorrow afternoon, arriving later morning and kicking to a very strong 10-12ft by dark, if not for the odd bigger clean-up set across the South West.

Mandurah should build to 3-4ft with 3ft sets late across Perth, easing from a similar size Sunday morning. The source of this swell was a broad, healthy and slow moving frontal progression firing up south-west of us the last couple of days.

Winds look good and offshore out of the E/SE tomorrow across Margaret River, SE further north ahead of afternoon sea breezes. Sunday should then see S/SE tending SE winds across Margs, S/SE further north ahead of S/SW sea breezes.

Into Monday, our second pulse of large, long-period SW groundswell is due to fill in, generated by tight though very intense low forming on the backside of the progression linked to the weekend’s swell.

A fetch of severe-gale to storm-force W/SW winds will be projected through our south-western swell window before the low tracks east-southeast and further east.

The size of this secondary pulse looks a bit smaller than forecast on Wednesday and more so 10ft with the rare 12ft’er across the South West, 3ft+ in Mandurah and 2-3ft across Perth. 

Winds look more S/SE than SE with semi-protected spots the go for experienced surfers, with Tuesday windy though more offshore with strong SE winds.

Cleaner conditions are possible through the rest of the week but the swell will become small, with background mid-period energy on the cards for the South West, tiny to the north. Therefore make the most of the coming swells.
