Best Days: Today South Coast, tomorrow morning South Coast, Friday South Coast protected spots, possible Mid Coast Saturday morning, Sunday morning South Coast, Monday South Coast, Tuesday South Coast

Features of the Forecast (tl;dr)

  • Easing SW swell tomorrow with strengthening N-N/NW winds
  • Mix of moderate sized W/SW groundswell and building SW energy with strong NW tending W/NW winds ahead of a late W/SW change
  • Mix of swells Sat with mod-fresh but easing SW winds, possibly S/SE early on the Mid and W/NW early down South
  • Easing surf Sun with local offshore winds and weak sea breezes
  • Moderate sized SW groundswell for Mon AM with local offshore winds ahead of weak sea breezes
  • Easing surf Tue with N winds


Great waves across both regions yesterday with large surf to 4-6ft across the South Coast and 2ft to occasionally 3ft on the Mid Coast with morning offshore winds and weak sea breezes.

This morning the surf is still great with clean 4ft+ waves off the South Coast and 2ft waves across the Mid Coast with a beautiful setting moon. The surf will continue to ease through the day as winds shift N/NW, favouring the South Coast.

Great scenes and surf this morning

This week and next (Aug 3 - 11)

Looking at tomorrow and winds will strengthen out of the N-N/NW along with a further drop in swell as a mid-latitude low forms in the Bight and pushes east.

Middleton looks to ease back from 2-3ft, tiny and wind affected on the Mid Coast.

Moving into Friday we've got a mix of W/SW groundswell and lower-period SW swell due to build across both coasts, generated by a significant but poorly aligned low that developed south-west of Western Australia on Monday.

The tight, storm-force fetch was mainly aimed towards Indonesia but due to the size and strength we should see moderate levels of W/SW groundswell for our state on Friday, while the remnants of the low are now aiming a patchy fetch of strong to gale-force SW winds through our south-western swell window.

This should produce an additional SW swell for the afternoon.

The Mid Coast looks to offer 2ft+ sets Friday with Middleton coming in around 4ft. The remnants of the northern flank of the low is expected to push through on Friday, bringing strong NW tending W/NW winds, shifting W/SW later into the afternoon.

Saturday then looks average but doable in the wake of the low, with moderate-fresh SW winds down South (outside chance of early W/NW breeze), similar on the Mid with possible early S/SE winds and easing 1-2ft sets.

The low itself might generate some weak S/SW swell for Saturday down South but the models diverge on its strength so check back here on Friday.

Sunday looks smaller but cleaner with tiny waves on the Mid Coast and easing surf from 2-3ft likely down South under local offshore winds.

Moving into Monday, and a strong SW groundswell is due to peak across the South Coast, generated by a strong polar low that is due to form east of the Heard Island region tomorrow, producing a great fetch of W-W/NW gales.

A good 4ft of swell is due from this low Monday morning, easing through the day with tiny 1ft sets on the Mid Coast. Winds look great and locally offshore ahead of sea breezes with N/NW winds on Tuesday as the swell eases.

Longer term there's nothing too significant storm or swell wise for the rest of next week, so make the most of the current energy and incoming swells.
