Western Australia Surf Forecast by Craig Brokensha (issued Monday 18th November)

Best Days: Dawn tomorrow, Thursday morning, Friday morning, Saturday morning, early Sunday

Recap

A small clean wave across the South West swell magnets on Saturday, still hanging in at 1-2ft across Mandurah, tiny to the north. Sunday was smaller again with onshore winds.

Today cleaned up, but there was hardly any swell left on the coast.

This weekend and next week (Nov 19 - 24)

Later today a new and inconsistent W/SW swell is due to arrive, peaking through tomorrow across the state. There's been no change to the expected sized with 4-5ft sets across the South West swell magnets, 1-2ft in Mandurah and 1-1.5ft in Perth.

Winds will only be favourable at dawn tomorrow and S/SE, quickly shifting S/SW and then SW through the day.

This will be linked to a weakening front pushing up and into us, bringing a mid-period increase in swell for Wednesday afternoon and Thursday morning, with a better and stronger swell for Friday/Saturday.

The first weaker swell will be generated by a broad fetch of strong W/SW winds today and tomorrow.

Margs should build to the 5-6ft range through Wednesday afternoon, 2ft+ in Mandurah and 2ft in Perth, easing back through Thursday from a touch less size.

Winds will be poor Wednesday and strong from the SW, easing through the day, while Thursday morning looks better with light SE breeze across the northern half of the cape in the South West, E/SE to the north, giving into sea breezes.

Friday morning should be nice and clean with a morning E/SE offshore with smaller amounts of swell ahead of the new swell building into the afternoon.

This will be generated by a stronger frontal system firing up in our swell window mid-late this week, producing strong to near gale-force W/SW winds.

6ft sets are likely when the swell kicks in Friday afternoon, easing back from the 5-6ft range Saturday morning. Mandurah looks to come in around 2ft, 1-2ft on the sets in Perth with a fresher morning SE breeze Saturday morning, strong S/SW into the afternoon.

Longer term there isn't anything too significant on the cards for our region, so make the most of the coming swells and windows of cleaner conditions.
