The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Dunes.
First thing you need to know: there’s a big gap of dead quiet at the start. We’re looking at a solid week of nothing worthwhile, from now until about the end of July. The water temp is sitting at 76°F which is about average for this time of year, so at least the swim is nice while you wait.
The first real whisper of action shows up on the morning of Thursday, July 30th. It’s a tiny 2ft south-west swell, but it’s got a super long 17 second period, which is a proper groundswell. The energy is moderate (346) but the wind is cross-off, so it’ll be clean. Honestly, it’s still pretty marginal – more of a paddle and a hope than a go-out.
The surf starts to build from Saturday, August 2nd. Sunday afternoon, August 2nd, is where it gets interesting. Dunes gets a solid 5ft south-west swell, period holding at 16 seconds, and the wind drops to a light, cross-off breeze. The combined energy jumps to 1029 (strong). This is the first real standout of the outlook – clean, lined-up waves with some proper push. It’s excellent for experienced surfers. The crowds here are possible, so keep an eye out.
Monday, August 3rd, keeps the run going. Same 5ft south-west swell, but the wind swings offshore in the afternoon. That’s a glassy, clean face all afternoon. Energy is still strong (911). This is your other highlight – a string of good, clean days.
After that, it drops off a little. Tuesday is smaller at 3ft, and the wind is fresh offshore on the 4th morning, which is clean but a bit strong. The swell picks up again on Wednesday, August 5th, with a 4ft south-west swell and a long 17 second period, but the wind is a moderate cross-off.
Then we get a serious pulse on Thursday, August 6th morning. Swell hits 6ft from the south-west, period a massive 20 seconds, and the energy is enormous (3045). That’s a very strong, long-period groundswell. The wind is strong offshore, so it’s going to be clean but incredibly powerful. This is for experts only – over 8ft and it’s just for the brave. A point break or reef setup would love this, but at a beach break, that long period can make it close out. Worth a look if you’ve got the skills.
Friday, August 7th, is still pumping with 5ft and offshore winds in the morning. Energy is still huge (1566). The weekend eases back to 5ft and 4ft, with cleaner conditions on Saturday morning.
So, the best on offer? Sunday, August 2nd afternoon and Monday, August 3rd afternoon are the clean, consistent, excellent picks. For the big wave chargers, Thursday, August 6th morning is the one to circle, but it’s a beast.
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.
