South Australian Forecast by Craig Brokensha (issued Monday 2nd April)

Best Days: Both coasts tomorrow, South Coast Wednesday morning, South Coast Friday morning, South Coast Saturday

Recap

Great Surf Saturday across both coasts with clean 3-4ft waves off Middleton and clean 2ft surf on the Mid Coast. Sunday was a bit smaller across both regions but nice and clean again through the morning ahead of sea breezes and a stronger onshore change.

This change has lingered into this morning along with a new SW groundswell, while the Mid Coast was around 1ft, though has kicked a little more now with 2ft sets at magnets (shown below).

This week and weekend (Apr 3 - 8)

Today's SW groundswell pulse was generated by a strong fast tracking front passing under the country over the weekend, and we've since seen another slightly weaker but broader front push through and under us.

A secondary pulse of SW groundswell is due off this front for tomorrow morning, coming in at 3-5ft across Middleton, while maintaining 1-2ft sets on the favourable parts of the tide on the Mid Coast.

We'll see the swell ease through the afternoon and further into Wednesday back to 3ft to occasionally 4ft off Middleton and 1-1.5ft on the Mid Coast.

Winds will unfortunately linger from the SW but be only light across the South Coast tomorrow, creating workable conditions, while the Mid Coast will more than likely see an early S/SE breeze.

Wednesday looks a bit cleaner with a light E/NE-NE offshore before sea breezes kick in.

A reinforcing SW groundswell is due later Wednesday and more so Thursday morning, generated by weaker trailing frontal activity pushing under the country today and tomorrow.

This will likely keep Middleton around 3ft+ Thursday morning and 1ft on the Mid Coast, easing slowly through Friday, though a weak persistent fetch of distant W/SW winds is likely to keep the Mid around 1ft.

Winds unfortunately look to revert back to the SE on Thursday morning, with E/NE-NE breezes Friday morning, but Saturday looks cleanest with smaller easing surf under a N/NE offshore.

Longer term an onshore change is due Sunday with some new W/SW swell due mid-late next week. More on this Wednesday.
