South Australian Surf Forecast by Craig Brokensha (issued Monday March 29th)

Best Days: Keen surfers on the South Coast magnets tomorrow morning, Thursday, Friday and Saturday mornings, later Sunday and Monday for the keen on the Mid Coast

Features of the Forecast (tl;dr)

  • Small, inconsistent background swells this week with favourable morning winds
  • Building SW swell Sunday with SE winds, easing Mon with S/SE winds
  • Smaller, easing swell Tue with a morning E/NE breeze, cleaner Wed down South


Bumpy, grovelly waves across both coasts Saturday, cleaner Sunday but only surfable down South and fun across the swell magnets, tiny on the Mid.

Today the surf is smaller but clean again down South, tiny to flat on the Mid.

This week and next (Mar 30 – Apr 9)

The coming week isn't too special at all regarding swell, though conditions look favourable and clean each morning ahead of sea breezes.

The surf looks minimal in size, not really topping 2ft across Middleton and that being tomorrow, and then Thursday/Friday, with tiny waves on the Mid, possibly 1ft late week.

With a N/NE-NE wind tomorrow morning try the exposed beaches down South, same Thursday and Friday mornings with a light N/NE offshore.

Now, as touched on the last few updates, we'll finally see a bit more activity from the weekend, that being Sunday into next week as a good, polar frontal progression pushes slowly east into our swell window, strengthening on approach through the weekend.

An initial relatively weak cold front will generate an elongated fetch of pre-frontal W/NW winds, energising the Southern Ocean for a stronger, better aligned front, projecting a fetch of strong to gale-force W/SW winds through our south-western swell window Friday evening through Saturday.

This should produce a moderate sized mid-period SW swell that'll build Sunday, peaking later in the day, then ease slowly Monday. The easing trend will be slowed by weaker, trailing W/SW winds through our swell window, but the power will drop with a drop in period.

Size wise, Middleton should build from a small 2ft+ early to 3-4ft into the afternoon, with the Mid Coast seeing 1-1.5ft sets, easing from a similar size Monday morning.

Winds won't be too favourable for the South Coast Sunday with a change pushing through Saturday, linked to the swell producing front, leaving SE winds across the coast, S/SE on Monday as the swell eases.

Tuesday looks a touch better with a E/NE morning breeze, best Wednesday and more offshore but the swell will be smaller and easing from 2ft to possibly 3ft across Middleton.

Longer term there's plenty more activity on the cards but winds look to be the main issue. More on this in the coming updates.
