Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 4th November)

Best Days: Tomorrow morning, Friday morning keen surfers in the South West, possibly next Wednesday

Recap

Not the cleanest but OK conditions for keen surfers across Perth and Mandurah yesterday morning, onshore and poor in the South West but OK in protected locations late with a new swell.

Today the SW groundswell has peaked with good though inconsistent, clean 6-8ft sets across the South West, 2-3ft in Mandurah and 2ft+ across Perth.

This week and weekend (Nov 5 - 8)

The current SW groundswell is now peaking and we'll see it easing later today, dropping back further tomorrow from the 6ft range on the sets across the South West, 2ft in Mandurah and 1-2ft in Perth.

Winds will be strong and offshore out of the E-E/SE, easing through the day ahead of sea breezes.

Friday now looks a bit better with winds from the E/SE but they'll be strong and the surf tricky as the swell eases further.

Into the weekend, our fun, but inconsistent new SW groundswell is due to fill in, generated by a storm that developed south-east of South Africa and was initially strong but since has weakened through our medium-range swell window.

The swell should build to an inconsistent 4-6ft Saturday afternoon and then ease from a similar size Sunday morning.

Conditions will be best as the swell builds on Saturday with a morning E/NE offshore, giving into afternoon sea breezes/a change as a trough moves through, leaving less than ideal S/SW winds in its wake. Perth and Mandurah may see a better S'ly early but we'll review this Friday. Size wise there's nothing of significance due north of Margs in any case with 1-2ft sets in Mandurah, tiny across Perth.

The trough is due to deepen into a low under the Bight and as it does so, strengthening S/SW winds will be seen on its western flank, kicking up a weak, S/SW windswell for us on Tuesday.

This swell will have no size and power, with strong onshore W'ly winds Monday, shifting S/SW into Tuesday.

Wednesday looks clean again with winds likely swinging back offshore as the mid-period S/SW swell eases.

Longer term mid-latitude frontal activity is due late week, but more on this Friday.
