Western Australian Forecast by Steve Shearer (issued Fri November 1st)

Features of the Forecast (tl;dr)

• Onshore winds for the weekend with a bump in size Sat, extending into Sun
• Offshore winds Mon AM with small swells
• More size now expected next week with rolling moderate SW swells from Tues 
• Onshore flow expected Tues-Thurs, may tend more S’ly Fri 
• Winds swing offshore again from Sat with a good run of sizey swells ahead from the weekend

Recap

Size was roughly in the f/cast range yesterday with 3-4ft sets in the SW, smaller 1-2ft north of Bunbury with a window of offshore E-E/SE winds before S’lies. Not much on offer today with 2ft sets in the SW, tiny elsewhere. Clean conditions early with light SE breezes before a SW seabreeze kicked in.

A few small fun ones yesterday

This weekend and next week (Nov2 - Nov 8)

Not much change to the weekend outlook. A coastal trough is moving inland with a front sweeping across the SW corner. That will bring onshore SW winds tomorrow, tending S/SW’ly on Sun, with just a brief window of SE winds north of Bunbury. 

We’ll see surf generated by the front build into the 4-5ft range across the SW corner tomorrow, smaller 2ft in the North.

Size should hold at similar sizes Sun. There should be just enough swell for a few fun waves at more protected spots in the SW between the Capes. 

Next week still looks iffy for winds as a node of the long wave trough steers fronts into the SW while slow moving high pressure sits in the Central Indian Ocean. Those fronts will maintain a moderate sized series of SW pulses from Tues.

Expect a low point in energy Mon with offshore winds for the morning and a’noon seabreezes. Size should top out around 3ft in the SW, tiny in the north.

A weekend fetch tracking between 70-100E brings the first of a series of SW pulses Tues (see below). These pulses look to be of similar magnitude- up in the 5-6ft range in the SW with some bigger sets on exposed reefs, 2-3ft in Mandurah, 2ft in Perth.

We should see a small dip in size Wed and another pulse Thurs. 

A more intense low tracks towards WA Wed into Thurs and brings a stronger pulse building Fri into Sat. 

This may push into the 6-8ft range under current modelling.

By Fri we should start to see high pressure slip under the state with a chance for winds to shift SE-E on Sat. 

This should see a good run of offshore winds and sizey surf from Sat, with a fetch of gales over the weekend in the near swell window looking to generate a sizey swell for Mon.

We’ll see how that looks on Mon. Until then, have a great weekend!
