Western Australia Surf Forecast by Craig Brokensha (issued Friday November 5th)

Best Days: Tomorrow, Sunday morning, Margs Monday morning

Features of the Forecast (tl;dr)

• Reinforcing mod-large S/SW swell filling in tomorrow with light E/NE winds and weak sea breezes in the South West (light SE tending strong S/SW in Perth and Mandurah), easing Sun with E/NE tending S/SE and then strong S winds (S/SE Perth and Mandurah in the AM)
• Fading surf Mon with a small reinforcing S/SW swell and morning E/SE-SE winds, stronger S/SE into the afternoon
• Slow period thereafter

Recap

Plenty of swell with variable, workable winds across the South West yesterday and 6-8ft sets on the exposed breaks, a little bumpy and to 2-3ft in Mandurah, peaky and to 2ft across Perth.

Conditions deteriorated into the afternoon as a trough moved in and winds are still lingering from the SW across the South West with the swell holding 6-8ft. Mandurah was cleaner and a little smaller to 2ft with peaky 1-2ft waves across Perth with light winds.

This weekend and next week (Nov 6 - 12)

The swell will drop slightly this afternoon and further early tomorrow, but our reinforcing pulse of good S/SW swell will arrive shortly after dawn in the South West, peaking through the day.

The frontal system linked to this swell is currently south-southwest of us generating a fetch of strong to gale-force SW winds.

It'll clear slowly to the east this evening, with winds improving tomorrow across the South West, further Sunday.

Size wise Margs should build to 6-8ft with 2ft+ waves in Mandurah through tomorrow afternoon, holding 2ft on the sets across Perth.

Winds will be light offshore out of the E/NE across Margs now ahead of weak sea breezes, with light SE tending stronger S/SW winds in Perth and Mandurah.

Sunday should see similar early E/NE winds in the South West, shifting S/SE late morning then stronger S'ly into the afternoon, with S/SE tending strong S/SW winds in Perth and Mandurah.

The swell will be on the way out, tiny in Perth, 1-2ft across Mandurah and 4-6ft across Margs.

A small reinforcing S/SW swell should slow the easing trend on Monday morning, generated by a small front firing up on the swell producing system for tomorrow. It'll be late in our swell window and only likely keep the South West around 3-4ft, easing through the day. Perth and Mandurah will be tiny.

Conditions will remain favourable with a moderate E/SE-SE offshore wind Monday morning , stronger S/SE into the afternoon and then less favourable, strong SE winds into Tuesday as the swell fades.

As touched on the last couple of updates, a strong and significant blocking high will setup south-west of us during next week, blocking our major swell windows leading to a run of small surf all of next week and into the following week. This may end into the second half of November but in the meantime make the most of the current surf. Have a great weekend!
