The Lowdown
Alright, surfers, Rusty here with the full rundown on what’s coming our way.
We’ve got a solid run of surf kicking off from Monday the 14th, and it’s looking like a week of mostly clean, shoulder-high waves from the southwest. The water’s sitting at 75°, which is just about bang on average for this time of year, so no surprises there.
The standout window is hands down Monday morning at Dunes. We’ve got a clean 5ft SW groundswell with a nice 14-second period, and the wind is a light cross-offshore. That’s the kind of combo that’ll have you grinning ear to ear. Wave energy is sitting at a healthy 857 (moderate). Conditions are clean and the vibe is good – just be aware crowds are possible here, so get in early.
Tuesday morning (15th) keeps the same 5ft SW swell, but the wind picks up a bit to a moderate breeze. Still cross-off and clean, so it’s worth a paddle. The energy drops slightly to 699, but it’s still fun.
Wednesday morning (16th) brings back those light cross-off winds with a clean 5ft SW swell. Energy’s up to 752. It’s very good, consistent, and the reef setup should be handling that 14-second period just fine.
Thursday (17th) sees the swell drop to under 3ft and the wind turns a bit messy. The morning might offer a tiny window with a light cross-off, but the energy’s weak at 326. I’d probably give it a miss.
Friday morning (18th) is small and clean with 2ft and light cross-off winds, but the energy is only 271. It’s a session for the longboard or a learner cruise.
Now, Saturday the 19th is where things get interesting. The morning serves up a punchy 6ft WSW swell with a 16-second period, and it’s clean with a moderate cross-off. Energy jumps to 1857 (strong). This is groundswell with serious push. However, by the afternoon, that swell jumps to 7ft, and the wind swings cross-shore. The model’s saying it might be too big for the break, and at that size, it’s expert territory only. If you’re solid and hungry, the morning window could be magic.
Sunday morning (20th) still has a solid 6ft WSW swell with light cross-off winds. Energy is 1065 (moderate to strong), and it’s being called excellent for experienced surfers. That’s a big call. If you’ve got the skills, get after it.
From Monday the 21st through to the end of the month, the pattern settles into smaller, cleaner mornings and blown-out afternoons. The swell hovers around 3ft to 4ft, mostly from the SW, with light cross-off winds in the mornings. The afternoons get shredded by strong cross-shore winds, so your window is dawn patrol. Energy stays moderate, between 391 and 781.
A couple of late standouts to keep an eye on: Saturday the 26th morning has a fresh offshore wind and a small 3ft swell from the WSW – clean but weak. Then Sunday the 27th morning has a 5ft SW groundswell with a very long 17-second period and 1435 energy. The wind is a light cross-onshore though, so it might be a bit bumpy, and that long period could make it a bit straight at the beach. Still, it’s worth checking.
All in all, the best bet is Monday the 14th morning for the cleanest combo, with Saturday the 19th morning and Sunday the 20th morning offering the biggest, cleanest waves for the experienced crew.
Stay stoked.

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.
