The Lowdown
G’day, Rusty here, your local surf reporter. Let’s look at what’s coming up for Dunes over the next couple of weeks. Right off the bat, this reef break is set to see a lot of action, with consistent SW swell running through the whole window. The water temp is sitting at 75°, which is about average for this time of year.
The surf kicks off on Monday morning, the 10th of August, with a clean 4ft SW swell rolling in. The combined energy is a moderate 842, and with a long 15-second period, this is proper groundswell. Winds are light cross-off from the SSW at 6 mph, so the face will be clean. This is a solid start, but the real standout shows up later.
Tuesday morning the 11th sees the wind swing strong offshore from the SSE at 25 mph, blowing the swell down to 2ft. It’s clean but hard to paddle into.
Wednesday the 12th morning has a 4ft SW swell at 16 seconds, energy at 572, but a fresh cross-off ESE breeze at 22 mph. It’s clean, but conditions are marginal.
Then Thursday the 13th afternoon, things get interesting. The wind drops to glassy from the NW at 3 mph, and we’ve got a clean 3ft SW swell with a 14-second period. The combined energy is 311. This is a nice, mellow session.
Friday the 14th gets a 3ft SW swell with a long 17-second period (energy 493) but a cross-on breeze keeps it from being special.
Saturday the 15th morning is the pick of the first week. A clean 3ft SW swell, 16-second period, light offshore SSE wind at 6 mph, and energy of 470. It’s a proper glass-off morning for Dunes, and crowds are sometimes a thing here, so get in early.
Sunday the 16th looks okay.
Now into the second week, the swell pulses up. Monday the 17th afternoon sees a 4ft SW swell, 16 seconds, with energy jumping to 1098. Winds are cross-on.
Tuesday the 18th morning pumps up to 6ft SW swell, 17-second period, and strong energy at 1697. It’s a bit bumpy with a light cross-on breeze, but experienced surfers will find power.
The true standout is Wednesday the 19th morning. Dunes is looking prime: 6ft WSW swell, 16-second period, and massive energy of 1611. The breeze is light cross-off from the SSE at 9 mph, so it’s clean. This is excellent surf for experienced crew—over 5ft so it’s pushing it for beginners, but for the regulars, this is the session to circle.
Thursday the 20th morning also fires with a 5ft WSW swell, 14-second period, offshore SSE wind at 16 mph, and energy of 1014.
By the end, Saturday the 22nd and Sunday the 23rd still hold 5ft and 4ft SW swells, with offshore or clean cross-off winds.
Bottom line: the 16-day run has surf nearly every day. Wednesday the 19th morning is your standout—big, clean, and powerful. Don’t sleep on Saturday the 15th morning for a cleaner, smaller session.
Stay stoked,
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.
