Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 9th September)

Best Days: Friday onwards

Recap

A slight improvement in conditions across the South West yesterday morning though the swell was still maxing and to 10-12ft or so, a bit cleaner to the north and to 4-5ft across Mandurah, 3ft+ across Perth.

Today all locations are much cleaner and the surf is pumping across some spots with 6-8ft of lumpy and improving surf in the South West, straighter and to 3ft in Mandurah and Perth.

This week and weekend (Sep 10 - 13)

We'll see a fresh pulse of W/SW tomorrow ahead of a larger longer-period swell on Friday, generated by continued and significant frontal activity through our western and south-western swell windows over the past couple of days.

Tomorrow's initial mid-period swell will arrive with some windswell from a mid-latitude front pushing up and into us, bringing onshore W/SW winds, stronger in the morning but easing into the afternoon.

The large swell for Friday will be met by light local offshore winds as the front quickly clears to the east and there's no change to the expected size with the South West due to peak around 10-12ft+ with 4ft waves around Mandurah and 3ft+ surf across Perth.

Afternoon sea breezes are due across all locations, though relatively weak in the South West, stronger around Perth and Mandurah.

The swell is expected to start easing into the afternoon, smaller Saturday as winds remain favourable and out of the SE across Perth and Mandurah, more variable across the South West.

From Sunday we'll see building levels of groundswell, becoming large and with favourable winds as a conveyer belt of polar frontal systems fire up and stretch from the west of the Heard Island region out to under us.

An initial fetch of W'ly gales should produce a new swell for Sunday, building to 6-8ft across the South West, 2-3ft in Mandurah and 2ft across Perth. A trailing fetch of slightly stronger winds should generate a larger pulse for Monday/Tuesday. This looks to reach 8-10ft or so in the South West, 3ft in Mandurah and 2-3ft across Perth.

Conditions look favourable and clean with offshore E/SE winds across all locations Sunday as the first swell builds, stronger E/NE on Monday and then E'ly Tuesday ahead of a weak change.

We'll confir, this on this Friday though.
