The Lowdown
Alright, Rusty here, let’s talk about Dunes.
We’ve got a solid little run of surf shaping up over the next couple of weeks, but it’s not all go. The first few days are a bit of a write-off, so don’t get too excited just yet. Saturday the 22nd is a no-go – the wind’s got it all chunky and cross, and the energy (671) just isn’t lining up right. Sunday the 23rd is cleaner but still only marginal, with the swell dropping off.
Patience. Monday the 24th is where we start to see the light. The morning session is the one to aim for: clean, offshore wind from the southeast, and a nice 3ft swell from the west-southwest. The period is a long 16 seconds, so that’s a proper groundswell, meaning it’ll have some real shape and push. The energy (652) is moderate, but that offshore breeze will make it feel way better than the numbers suggest. It’s a reef break that’s consistent and exposed to the southwest swell, which is exactly what the optimum direction calls for. This is the standout for the first week, no doubt.
Tuesday the 25th keeps the clean offshore wind in the morning, but the swell drops a touch. Still a fun, clean wave. Then things get a bit messy again through the middle of the week.
Now, here’s the exciting bit. We’ve got a bigger pulse coming in around Thursday the 27th. Swell jumps to 6ft from the southwest, with a very long 16-second period. The energy gets strong (1750). That’s a serious amount of water moving. The wind is a fresh offshore in the morning, which is perfect, but the wave height is pushing into expert-only territory. This is a true stand-out session for experienced surfers only.
After that, the surf settles back down, but there’s another promising window. On the 1st of September, we get another solid 6ft southwest groundswell with a 17-second period. That’s a long-period, powerful swell, perfect for a reef setup like Dunes. The morning wind is light and cross-offshore, making for excellent conditions. Energy is very strong (1700). This is your second-week highlight, but keep in mind it’s a long-range call, so don’t book the week off just yet.
The morning of the 2nd of September offers similar quality, just a touch smaller. Then the last decent chance is on the 6th of September, with a clean offshore wind and a moderate 4ft swell.
Crowds can be a thing here sometimes, so factor that in for the standout days.
Overall, the best wave of the whole run is Thursday the 27th for the big, powerful stuff, and the 1st of September for the long-period beauty.
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.
