Recap

Everywhere offered much cleaner and better surf yesterday with easing sets from 8ft+ across the South West under a light offshore wind, 3ft Mandurah and 2-3ft in Perth.

Today was a bit smaller and with more north in the wind, though a new SW groundswell is providing quality sets across the South West and workable options (now poor with stronger winds).

This week and next (Jun 6 - 14)

We’ve got deteriorating conditions ahead of an approaching mid-latitude frontal progression with strengthening N tending N/NW winds due to whip up some local windswell tomorrow, shifting W/SW into the evening and then abating rapidly Friday.

This will be as moderate to large levels of mid-period W/SW swell fill in from the front itself, peaking Friday morning and then easing.

Sets to 10ft are still due across the South West, 3ft in Mandurah and 2-3ft in Perth and winds look to back off earlier, tending variable across the South West with E/SE tending S/SE winds to the north.

Saturday looks to see easing surf and with an early E/NE breeze that will quickly strengthen and shift NW so the window is small.

This shift in wind will be associated with the next incoming mid-latitude system and it looks to be broader, stronger and slower moving. As a result an XL, stormy W/SW groundswell is due from this system, with it building strongly later Sunday along with some localised windswell as the low pushes into us.

Strong to gale-force W’ly winds and 12-15ft surf look to leave no quality options with stormy 4-5ft waves in metro locations, easing Monday as strong W/NW winds persist.

The low is due to clear east and break down Tuesday, allowing winds to shift S/SE and we should still be seeing large surf, easing back from 6-8ft waves in the South West, 2-3ft Mandurah and 2ft Perth.

Behind this there’s plenty more swell due but local winds look to remain dicey at best. More on this Friday.
