Best Days: South Coast magnets tomorrow morning, late on the Mid Coast Sunday for the keen (similar Monday), South Coast Tuesday morning, South Coast Wednesday and Thursday mornings

Features of the Forecast (tl;dr)

  • Building SW swell Sunday with variable winds ahead of a weak change, peaking Mon PM with morning SE winds, stronger S/SE into the afternoon, easing Tue with E/NE morning winds
  • Easing swell Wed with a light N/NE offshore, smaller Thu and N'ly early


Tiny, clean 1ft waves with a background W/SW swell on the Mid Coast while the South Coast has been perfectly clean and lined up each morning with fun 2ft sets across Middleton, best at more exposed breaks.

This weekend and next week (Apr 3 - 9)

Tomorrow should be another good, clean one across the South Coast swell magnets with background swell to 1-2ft across Middleton and a moderate N/NW breeze, shifting W'ly late afternoon. Hit the swell magnets in the morning for the best waves.

Now, winds should be variable and locally offshore on Sunday morning but a shallow change is due through the morning as a trough pushes through, linked to the frontal progression bringing the swell from Sunday afternoon through Wednesday.

The frontal progression linked to our coming swell (which looks to be a bit better than mid-period energy but not proper groundswell) is currently starting to develop south-west of Western Australia.

An initial weak, though broad front will strengthen while pushing east under the country this evening, with a good fetch of strong to gale-force W/SW winds due to be projected through our south-western swell window, followed immediately behind by a slightly more consolidated fetch of W'ly gales tomorrow evening and Sunday.

The initial front should produce a fun pulse of W/SW swell for the Mid later Sunday to 1-1.5ft, similar Monday while the South Coast will start slow Sunday morning and to 2ft, building to 3ft+ late in the day building further through Monday with 4ft surf due into the afternoon, easing slowly from 3-4ft on Tuesday.

Winds will favour the Mid Coast with a late S/SE breeze developing Sunday, fresh SE on Monday morning, stronger S/SE into the afternoon.

Tuesday will start to improve down South with winds tending E/NE through the morning but Wednesday looks best with variable N/NE winds and easing 3ft sets across Middleton.

Thursday morning at this stage also looks good with a N'ly offshore before a trough brings a S change during the day.

Longer term the outlook is still tricky as we'll see a tropical cyclone off the North West of WA likely drifting south to mid-latitudes, throwing a few spanners in the works. We may see a mid-latitude low pushing in late next week, but check back here Monday for a clearer idea on next weekend and beyond. Have a Happy, Safe Easter!
