The Lowdown
Righto, let's have a look at what's on offer at Dunes. It's a consistent reef break, exposed to the southwest swell, and the wind we want is from the southeast.
Right now, the water’s sitting at 75°, which is pretty much bang on average for this time of year – nothing unusual there.
The first bit of action worth getting excited about is this Sunday afternoon, the 9th. We’ve got a solid 5ft swell rolling in from the southwest with a super long 17-second period. That's proper groundswell energy, and the combined energy reading is a hefty 1416. The wind is a gentle offshore from the SSE. This is going to be clean and powerful, but at this size, it’s definitely one for the experienced crew. Good, solid start.
Monday the 10th still has some nice push, with 4ft of that long-period SW groundswell (842 combined energy) and a clean cross-off wind in the morning. The afternoon gets a bit messy with a cross-shore wind though.
We hit a bit of a lull mid-week. Tuesday the 11th drops right off with tiny 2ft waves, and even though the wind is strong and offshore, it’s just too small and hard to paddle into. That stretch of poor-to-marginal conditions runs through until Friday morning the 14th, when things perk up again.
Friday the 14th is a bit of a gem, especially the afternoon. We’ve got 3ft of southwest swell with a lovely 17-second period, and the wind goes glassy – dead calm. That’s glassy conditions, my friends, and it’ll be a treat. The combined energy is still moderate at 465, but the quality will be high.
Saturday the 15th morning cleans up again, but the afternoon gets chopped out.
Now, the real standout is Monday the 17th morning. The swell jumps to 3ft with a 16-second period, and once again, we get glassy conditions. The combined energy shoots right up to 1136, which is a lot of grunt for that size. This is going to be exceptional, clean surf for the experienced surfer. Get on it.
That swell builds through Tuesday the 18th, with the morning showing 6ft of WSW swell and a clean cross-off wind. The combined energy is a massive 1800 – that's a lot of water moving. This is top-tier stuff, but at 6ft, it’s still more of an expert session.
We get a bit of a wind and weather problem mid-week, with onshore and cross-on winds bringing chop and light rain on the 19th. The swell holds big at 6-6ft, but the wind shuts it down.
Thursday the 20th is too big for the setup. We’re looking at 8ft of swell, and while the wind is clean early on, the file tells us the swell is predicted to be too big for this break. That's a miss for us, but a kite surfer would have a field day in that.
After that, the swell backs off into the 5-6ft range through the 22nd and 23rd, with clean conditions on the Saturday afternoon of the 22nd, but the wind is strong and offshore again on the 21st. There's a decent window that Saturday afternoon with light wind and clean 5ft swell.
The very end of the run, on the 24th, drops back to small, poor conditions.
So, the two absolute standouts in this 16-day window are Monday the 17th morning for that glassy, powerful groundswell, and Friday the 14th afternoon for the pure glass-off. Set your alarms.

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.
