Today's swell has reached a peak and will trend down through Friday.
Primary tabs
Friday is probably the pick of the period as we'll have the best conditions, though size will be only borderline surfable across metro beaches.
We’re looking at slowly easing swells from today into Sunday and Monday.
Fortunately, winds will tend light variable across all regions so conditions will be clean.
We’re still looking at a very significant groundswell arriving throughout Thursday, peaking in the late afternoon before easing slowly through Friday.
While all of this is going on, a much more significant system will have been tracking eastwards through the Southern Indian Ocean, generating a large groundswell that’s due to arrive Thursday.
Easing SW groundswell tomorrow with favourable winds for Perth and Mandurah, with lighter winds Friday across the South West and a new SW swell for the afternoon. Larger SW groundswell Saturday morning with good winds before lunch, deteriorating into Sunday with more large surf.
Average conditions across the South West until late week, with windows to the north from Wednesday, best Saturday morning with a new SW groundswell before winds go onshore.
Poor building W/NW windswell tomorrow with strong NW winds, with a larger W/SW groundswell for Sunday as winds swing SW through the afternoon. Easing swell with light winds (offshore across Mandurah and Perth) Monday morning. Good long-period SW groundswell building Wednesday afternoon, cleanest and easing Thursday.
Easing W/SW swells tomorrow with light winds around Mandurah and Perth, cleaner around Margs dawn Friday with a new S/SW groundswell ahead of freshening NW winds. Onshore winds all weekend with a large W/SW groundswell filling in Sunday, cleaner and easing Monday.
