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

Best Days: Later Friday in protected spots around Margs, Saturday morning all spots, Sunday morning all spots, Monday morning the pick of the period


Yesterday pumped in the South West with a large pulse of W/SW groundswell to 6-8ft across most breaks under offshore winds, while further north, winds started off less than favourable but swung offshore for a short period before sea breezes kicked in.

This morning the swell was easing and less favourable S'ly winds were blowing across the South West, but protected spots were still fun, with OK 2-3ft sets around Perth. Gero had good 3-5ft sets which were a little raw with the variable winds.

This week and weekend (Nov 6 - 9)

The end of the week will be poor conditions wise but there'll be plenty of swell on offer into Friday.

A vigorous and deepening mid-latitude frontal system pushing up and into us over the next two days will bring strengthening onshores to both coasts tomorrow (likely variable around Perth early and less so Gero) before the swell fills in Friday with strong but easing SW winds.

The South West should peak at a stormy 8-10ft with 3-4ft waves around Perth into the afternoon and building surf to 6ft+ around Gero. A late swing in winds to the S/SW around Margs should open up protected bays and points for business but the swell will be quite raw and unruly.

Saturday will be the day to surf though as winds swing offshore from the E/SE around Perth and SE up at Gero, while the South West should see variable winds from about Margs north (the further north the better). Perth should be easing from 2-3ft, Margs the 8ft range and Gero 6ft+.

Sunday looks to see good SE winds continue and a new SW groundswell is due to fill in through the afternoon, generated by a trailing but healthy polar front in the wake of the mid-latitude system pushing through Friday.

This swell should peak Monday morning to 4-6ft in the South West, 2ft in Perth and 3ft to occasionally 4ft up at Gero.

Next Monday onwards (Nov 10 onwards)

As touched on above, a new SW groundswell due to peak Monday morning will be met with offshore E/NE winds, creating excellent conditions across most breaks.

Into Tuesday the swell will ease but with onshore W/NW winds, so definitely plan around a surf Monday morning sometime.

Longer term a funky W/SW groundswell from a funky mid-latitude trough/ow pushing in from the west is due, but the make of this system leaves a lot to be wanted. The fetch won't be very well aligned for us, but still it should keep fun waves hitting most coasts into Thursday with winds from the southern-eastern quadrant. More on this Friday though.
