The Lowdown
Alright, Rusty here with the rundown on the surf for Dunes.
We’ve got a bit of a mixed bag coming, but there are definitely some windows to score if you’re on the ball. The best bet of the week is shaping up for Sunday the 30th of August, when a nice long-period groundswell arrives.
Sunday morning is looking choice. The swell is coming from the southwest at about 3ft with a period of 17 seconds and combined energy of 550 (moderate). That’s some proper groundswell, and with a light cross-off breeze from the southeast, the place should be glassy and clean. That long period will mean nice, well-shaped lines, though the sets might be a little spread out. It’s not huge, but for a reef like this, the quality will be sweet.
Then, if you can be patient, Monday the 31st of August is the real standout. The morning is set to be excellent, with a southwest swell of 4ft, a 16-second period, and combined energy reading 1216 – that’s strong wave energy. A solid push of swell with a light cross-off wind again. It’s going to be clean and punchy, but with the size and the reef, this one is for experienced surfers only. Beginners should sit this one out.
The wind stays clean for Tuesday the 1st of September morning too, with a slightly bigger 5ft southwest swell, though the report flags it as marginal. The energy is still strong at 1012. Worth a look, just keep your expectations in check.
After that, things get a bit choppy and dicey in the afternoons with onshore winds. There’s a run of poor surf kicking off around the 5th of September, with strong winds making a mess of things. The 13th of September is the only real light at the end of the tunnel – a Sunday morning with a 4ft southwest swell and a gentle offshore flow from the east-southeast. That should clean it right up. It’s a way off, so don’t count on it just yet, but it’s promising.
Rusty.

Information about the Dunes Surf forecast
The above surf forecast table for Dunes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dunes can be found by selecting the local surf guide option on the grey menu. Our Dunes surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Dunes) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Dunes may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
