This week and weekend (Feb 27 – Mar 4)

Today's onshore winds are linked to a broad but relatively weak frontal system projecting up towards us, with it bringing a mid-period increase in SW swell tomorrow, peaking through the afternoon.

The South West should build to 4-6ft with 2ft waves developing in Mandurah, 1-2ft across Perth as winds start to improve.

A S/SE'ly should be seen across Mandurah and Perth, with dawn S/SW winds around Margs, tending S/SE mid-late morning and likely holding into the afternoon.

Wednesday will be much cleaner with an E/SE offshore though the swell will be easing from 3-5ft across the South West, 1-2ft Mandurah and tiny in Perth.

Thursday morning looks smaller again, but later in the day we should see some new long-period swell filling in ahead of a peak Friday.

This swell was generated over the weekend and further today by a strong polar low in the Heard Island region.

A fetch of gale to severe-gale W'ly winds have generated a long-period SW groundswell for Friday, with an increase expected later in the day Thursday. Margs should kick to 4-5ft, with 1-2ft sets around Mandurah on dark, peaking Friday morning to 4-6ft and 2ft respectively, with 1-1.5ft sets in Perth.

A morning SE breeze is due Thursday morning, more offshore to the north ahead of a shallow S/SE change which will then leave S/SE winds into Friday morning.

The weekend should be cleaner as winds swing more offshore though the swell will ease and become small across Margs, tiny to the north.

Longer term there's nothing major on the cards with a large blocking high to our west keeping a lid on any major frontal activity.

This will create clean conditions but with no decent swell at all.
