The Lowdown
Alright, Rusty here, let’s talk about what’s on the menu for the Dunes. This is a consistent reef setup that’s exposed to the south-west, and it’s got a solid run of south-west groundswell coming through. The water temperature is sitting at 75°, which is pretty average for this time of year—nothing weird going on there.
The standout session is Wednesday afternoon, August 5th. It’s glassy, with the wind going calm and the swell hitting 5 ft from the SW at a long 16 seconds. The wave energy is moderate at 933, and the conditions are set up to be really clean. For an intermediate surfer, this is the cream of the crop.
Thursday morning, August 6th, is also looking good. The swell bumps up to 5 ft from the SW, still with that long 16-second period, and a light cross-offshore breeze from the SSE is keeping it clean. The wave energy is stronger at 1158, so there’s a bit more push. This one is better for experienced surfers, but it’s a solid option.
After that, things get a bit messy. From Thursday afternoon right through to Monday, August 10th, the wind picks up and the surf quality drops. There’s a lot of cross-shore and cross-offshore breeze, and the scores are low. The swell hangs around 5 ft to 5 ft, but the wind isn’t playing nice. Sunday morning, August 9th, has a strong offshore wind at 25 mph, which cleans it up but makes it a real paddle battle. Not the best for a relaxed session.
Tuesday, August 11th, the swell drops off to 2 ft–3 ft, and the energy is weak at 451. The wind is offshore, but the waves are small. Wednesday, August 12th, through Thursday afternoon, August 13th, the swell stays around 3 ft–4 ft. Thursday afternoon goes glassy again with a 3 ft SW swell, and that’s a nice little window for a clean, small-wave session.
Now, looking further out, Monday morning, August 17th, is a big one. The swell jumps to 6 ft from the SW, with a 17-second period and a moderate offshore wind. The wave energy is very strong at 1944. This is for experienced surfers only—it’s going to be a serious, powerful swell. The rest of that week, from August 17th to the 19th, the swell stays big, between 6 ft and 7 ft, with strong wind and energy. It’s a stretch for experts only, and the guidance shows the wind and tide are favorable, but the swell is predicted to be too big for this break on the 17th and 18th afternoons and the 18th morning.
Thursday morning, August 20th, rounds it out with a 5 ft swell from the WSW, a 14-second period, and a moderate offshore wind. It’s clean, with moderate energy at 953, and it’s a very good option to close out the run.
Overall, the best bet is Wednesday afternoon, August 5th, for that glassy, clean, classic reef session. The long period means the sets will be spaced out, which is great for paddling, but keep an eye on the tide. The bigger stuff in the second week is for the experienced crew.

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.
