Table - best surf conditions forecast for Dunes over the next 16 days.
Right folks, Rusty here. Let’s have a look at what’s on offer at Dunes.
We’re kicking off a bit slow, but don’t write it off. The first real sign of life shows up on Monday, July 13th. The morning session is where it’s at. We’ve got a clean 3ft swell from the SW, with a nice long period of 14 seconds. That’s some proper groundswell energy pushing in, and with a light cross-off breeze, it’s going to be tidy. The combined energy is moderate (432), so there’s a bit of push behind it. The water is bang on average for the time of year, sitting at 76°. This is the best session of the early week.
The morning of Thursday, July 24th, brings a solid pulse. The swell is a clean 5ft from the SW, period 17 seconds, and the combined energy kicks up to 1281 – that’s strong wave energy. The wind is fresh, but it’s cross-off, so the face will be clean. This is a good option, but that 5ft mark and the long period mean it’s a step up. It’s more suited to surfers with some experience.
Now, the standout. The real gem is the morning of Saturday, July 25th. The forecast is for 5ft from the SW, period 15 seconds, and a gentle breeze keeping it cross-off. The combined energy reads 979. Conditions are set to be very good. This is the one to circle on the calendar. That long, clean SW groundswell with a light wind and a reliable reef break like Dunes usually handles it well. Because it’s a reef, that long period won’t just close out; it’ll give you a proper, lined-up wave.
After that, the energy drops off into the last days of the forecast window. The morning of Monday, July 27th, looks fun with a clean 3ft and a moderate offshore wind, but it’s a definite step down from the weekend.
There’s a solid gap in the middle there, from the 14th to the 18th, where nothing really gets the heart pumping. But the 18th does have a morning with a gentle offshore and 4ft, so it’s not a total write-off.
Overall, keep your eyes on Monday morning the 13th for a clean start, and definitely lock in the morning of Saturday the 25th. That’s the one worth waking up early for.
Rusty out.

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.
