South Australian Surf Forecast by Craig Brokensha (issued Friday June 2)

Best Days: This morning South Coast, Mid Coast for beginners, South Coast tomorrow morning, Sunday, Monday and Tuesday morning before the swell fades

Features of the Forecast (tl;dr)

  • Large, easing S/SW swell Fri with fresh NE tending E/NE winds
  • Drop in size Sat with mod-fresh N/NE tending E/NE winds
  • Moderate sized S/SW groundswell building Sun with fresh NE winds
  • Easing swell Mon with lighter NE winds
  • Smaller Tue with N/NW winds
  • Building W/SW swell late week with strong W/SW winds


Average conditions to start of yesterday in the wake of a cold front clipping us early morning, but winds tended variable along with a large, building S/SW groundswell which pushed to an easy 6ft across the South Coast. The Mid Coast was in the 1-1.5ft range but inconsistent.

Today conditions are cleaner down South but suited to selected spots with a NE wind and easing 6ft sets, 1ft+ on the Mid Coast and glassy. Winds will shift more E/NE this afternoon, limiting clean options further down South.

Still the odd glassy one this AM, but much better down South

This weekend and next week (Jun 3 - 9)

The large surf that's currently breaking across the South Coast will drop steadily into this evening, with smaller, 3ft+ sets left across Middleton tomorrow morning with a great N/NE offshore wind.

Winds will shift E/NE into the afternoon, so try and surf before lunch for the cleanest and best conditions.

A very temporary low point in swell is due early Sunday ahead of a new pulse of S/SW groundswell, generated by a tight polar low that's currently south of the country.

A fetch of gale to severe-gale W/SW winds are being generated, with the swell due to build quickly through the day Sunday, kicking back to 4ft off Middleton through the afternoon. The Mid Coast won't see any size from this source, becoming tiny to flat.

Winds will be gusty from the NE all day on Sunday, favouring selected spots, with Monday offering easing 3ft sets as winds weaken but persist from the NE.

The synoptic setup responsible for the persistent north-east winds is developing but weakening mid-latitude lows moving in from the Bight, edging against high pressure.

With each low weakening, there's no shift in winds to the south-west or south-east, with Tuesday seeing a temporary shift to the N/NW along with small to tiny, easing surf.

The swell generating properties of each low looks poor and too far north of the Bight until later next week when we may see a significant progression pushing east.

This will bring building surf along with wind into Friday/next weekend but the models diverge on the strength and timing. Check back here on Monday for a clearer idea and have a great weekend!
