The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming up for Dunes. We’ve got a solid period of surf on the way, with the best action happening on the mornings when that offshore wind kicks in. Water temp is sitting at 76°, which is a touch warmer than what you’d usually expect this time of year – nice for a longer session.
Monday morning the 24th is where we start to see something good. Swell coming from the WSW at 3ft, with a period of 16 seconds – that’s proper groundswell energy, and with a clean SE offshore breeze at 16 mph, Dunes will be looking clean and inviting. The combined energy is sitting at 635 (moderate wave energy). Worth an early paddle.
Tuesday morning the 25th keeps the trend going: 4ft from the SW, 13-second period, and light SE offshore winds at 12 mph. Combined energy is 415. Good, clean conditions for a solid session.
The real standout of the whole run looks like Thursday morning the 27th. Swell jumps up to 6ft from the WSW, with a very long 17-second period. That’s a lot of energy moving through – combined energy is 1970 (strong wave energy). Winds are offshore from the SSE at 16 mph, making for clean lines. This one’s for experienced surfers only; it’s going to be well overhead and pretty powerful. If you’ve got the skills, this is your morning.
The following week, things get a bit more mixed. Monday morning the 31st offers 4ft from the WSW, 16-second period, and light E cross-offshore breeze at 6 mph – clean again, with combined energy at 943 (moderate). Tuesday morning the 1st of September hits 5ft from the WSW, 17-second period, with a light SSW cross-off breeze. That’s solid and clean, but not quite as perfect as the 27th. Combined energy 1178 (moderate to strong).
Towards the end, Saturday morning the 5th of September is worth noting: 4ft from the SW, glassy conditions with a 3 mph wind, and combined energy of 525. Should be clean and fun.
Overall, Thursday the 27th is the clear standout – best swell, best wind, best energy. Get on it if you can.
Rusty.

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.
