Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 7th October)

Best Days: Friday morning, protected spots Saturday morning, Sunday morning, 

Recap

Pumping surf across all coasts yesterday with a rapidly improving large swell with winds swinging offshore cleaning up 10-12ft sets in the South West, 3-4ft waves around Mandurahe and 3ft surf up at Perth. Weak sea breezes impacted the South West, while Perth remained clean into the evening.

Today the swell was smaller but a reinforcing SW pulse has kept 8-10ft waves hitting the South West and 2-3ft waves around Perth with strong and tricky E/NE winds. These winds should ease into the afternoon while tending more N/NE.

This week and weekend (Aug 8 - 11)

Tomorrow isn't looking as nice as the last couple of days as a weak change moves through resulting in S/SE winds across the South West, E/SE around Perth.

The Surf will be smaller and back to 4-5ft across the South West with 1-2ft sets around Perth, holding a similar size into Friday morning as winds swing further offshore from the E/SE across Margs, and E/NE up around Perth.

Later in the day when sea breezes are due, a strong but inconsistent pulse of SW groundswell is due.

This has been generated the last couple of days by a strong but small polar low firing up in the Heard Island region.

We should see exposed breaks in the South West kicking to 5-6ft later in the day, with Perth likely not seeing any size before dark.

A drop in swell is then due Saturday from an inconsistent 4-5ft and 1-1.5ft respectively. Another weak trough is expected to bring less than favourable S/SE winds to the coast Saturday morning (E'ly around Perth), fresher from the SE Sunday (E/NE Perth).

Next week onwards (Oct 12 onwards)

Nothing too special to talk about early next week with an easing swell and E/SE offshores Monday morning and then moderate pulses of W/SW swell but with S/SE winds Tuesday and Wednesday.

A very inconsistent but strong long-range W/SW groundswell is due into Thursday though, generated by a vigorous and slow moving polar frontal progression under South Africa tomorrow and Friday, weakening under Madagascar Saturday.

Although in our far swell window, a large and inconsistent long-period W/SW groundswell should result, with the fore-runners arriving through Wednesday ahead of the bulk of the swell Thursday, peaking to 6ft to occasionally 8ft across the South West and 1-2ft around Perth.

Winds are possibly a little dicey though and light to moderate from the W/NW, we'll have a closer look at this on Friday though.
