Recap

Poor conditions and average surf in the South West, building through the day with weak, windswelly waves to the north.

Today our better pulse of mid-period W/SW swell has filled in with much better conditions and 6ft+ surf across the South West, 2-3ft in Mandurah and 2ft in Perth. The swell has since started to ease as winds remain favourable.

This weekend and next week (Jun 4 - 10)

Conditions are a little mixed for tomorrow as we see today's swell easing in size, dropping from 4-5ft in the South West and 1ft to possibly 2ft in Mandurah and Perth. Locations north of Margs will see E/SE offshore winds, S/SE across Margs and tending S/SW into the afternoon.

Into the late afternoon our strong pulse of new SW groundswell may be seen but Sunday morning will reveal the peak in size, coming in at a great 6ft+ across the South West (8ft clean ups on the magnets) and 2ft in Mandurah and Perth.

This was generated mid-week by a strong polar low down near Heard Island and winds will swing back offshore across the South West with a light offshore E'ly (E/SE to the north) shifting SE into the afternoon and back to the E/SE late.

The swell is due to ease into the afternoon, back from a smaller 5ft on Monday morning in the South West with 1-2ft sets further north.

Conditions will remain clean with a fresh E/NE breeze, holding Tuesday but strengthening.

As touched on in Wednesday's notes, the first of a couple of pulses of new, inconsistent W/SW groundswell is due into Tuesday afternoon, with a secondary pulse for Thursday.

These swells have (and are still) being generated by back to back lows firing up south and south-east of South Africa, with both being similar in strength and size, but the second pushing a bit closer towards us.

The first swell for Tuesday afternoon will be the least consistent with the South West due to build to an inconsistent 6ft+ with infrequent 2ft+ waves in Perth and Mandurah, holding Wednesday ahead of the secondary pulse Thursday to a similar size.

A deepening low to our nwest will see winds strengthen from the E/NE further on Wednesday creating tricky conditions, holding Thursday and Friday before swinging around to the NW on the weekend.

Longer term some new, inconsistent W/SW groundswell is due next weekend with slowly improving winds following the change on Saturday but we'll have a closer look at this Monday. Have a great weekend!
