Recap

A stalling trough brought variable winds yesterday morning with relatively clean conditions across all locations but with easing levels of swell from the 6ft range in the South West, 2-3ft Mandurah and 2ft Perth.

This morning is smaller and weaker with cross-offshore winds.

This weekend and next week (Jan 4 - 10)

The coming period is much smaller and slower than the recent weeks with the Southern Ocean finally falling quiet.

With this there’s no significant storm generating system expected through our swell window with small to moderate sized pulses of mid-period swell due from the weekend through tomorrow.

A small pulse of SW swell due this morning is due to ease tomorrow back to 3-4ft or so across the South West with fresh S/SE-SE tending stronger S/SW winds. Perth and Mandurah will be tiny.

Into later tomorrow but more so Sunday a new mid-period SW swell is due, generated by weak frontal system that’s currently south-west of us (below left).

This will only likely kick up a weak 4-5ft wave later tomorrow across the South West, peaking Sunday with 1-1.5ft sets to the north along with fresh SE morning winds, and this is probably worth a look.

The swell will fade back through Monday but be much cleaner with a lighter E/SE offshore and easing 3-4ft sets across the South West.

There’s no new swell due into the middle of next week with the size bottoming out into Tuesday/Wednesday.

Small pulses of mid-period swell are due from Thursday, with the first being generated by a weak, flash in the pan burst of strong W/SW winds Sunday.

We’ll be lucky to get anything over 4ft from this in the South West with morning SE winds.

Similar sized surf looks to persist through Friday/Saturday while better swell generating potential looks to develop through next weekend.

We’ll have a closer look at this on Monday. Have a great weekend!
