Recap

Monday’s large, stormy surf backed off into yesterday and improved as the day went on as early lumpy conditions sorted themselves out in Perth and Mandurah. Fun 2-3ft waves were seen all day in Perth, a chunky and lumpy but decent 3ft in Mandurah while Margs backed off quickly from 8-10ft but with lumpy conditions persisting all day.

Today is smaller but cleaner across all locations, fun in metro locations.

This week and weekend (Jun 13 - 16)

We’ve got some fun surf due over the coming days with morning offshore winds and small to moderate swell pulses before things go a little funky into the weekend and next week.

Firstly tomorrow, a small-moderate sized mid-period S/SW swell is due across the South West, generated by a weak polar front. 4ft sets are due in the South West on the magnets, tiny elsewhere and with light E/SE-SE offshores and weak sea breezes.

Similar sized waves are due into Friday morning ahead of some inconsistent W/SW groundswell later in the day and Saturday morning, pulsing to 4-6ft across the South West with 1-1.5ft waves due in Perth and Mandurah.

Fresher E/NE winds are due Friday morning, shifting NE and then N/NE into the afternoon, with Saturday seeing trickier, fresh N/NE tending N/NW winds.

This shift in wind will be ahead of a broad strong approaching frontal system through the Southern Ocean, protruding into the Indian Ocean.

Various fetches of strong to gale-force W/SW winds should produce a large mid-period W/SW swell Sunday afternoon and Monday morning.

Good 6-8ft sets are due in the South West at the peak, 2-3ft across Mandurah and 2ft in Perth on the sets but with freshening W/SW tending SW winds in the South West, variable E/NE to the north, tending SW during the day.

Monday should see winds swing offshore from the E/SE across all locations and this is the pick of the period thanks to Tuesday being smaller but with early variable offshore tending NW winds.

Longer term, we’re looking at a strong polar frontal system projecting north-east towards us mid-week, bringing a low quality, windy increase in swell, cleaner and easing later week. Overall not great so get stuck in over the coming days.
