The Lowdown
Right, settle in. Rusty here. We’ve got a mixed bag coming our way over the next couple of weeks, but there’s a genuine standout session if you time it right. The swell energy is up there for a couple of days, and the wind looks like it could play ball.
First up, water’s sitting at 75°, which is pretty standard for this time of year – nothing weird going on there.
The main event is Dunes, a consistent reef break that’s exposed to the SW. The best windows are kicking off Wednesday the 5th of August and running into Thursday the 6th. On Wednesday morning, we’re looking at a solid 5ft SW swell with a long 17-second period – that’s proper groundswell. Energy is strong, coming in at (1038). The wind is offshore from the SE at 12 mph, so the faces will be clean. This is the pick of the fortnight for experienced surfers. Thursday morning is also a cracker: 5ft SW swell, 16-second period, even more energy at (1172), and light cross-offshore winds. That’s your other top window. Just be aware that with that long period, Dunes might get a bit straight for a beach break, but as a reef, it should handle it nicely.
Before that, Sunday the 2nd has a 4ft SW swell with a 15-second period. The energy is moderate (482), and the wind is cross-offshore from the east. It’s not huge, but it’s clean and glassy enough for a fun session. Monday the 3rd is a write-off with strong cross-shore winds.
After that early-week flurry, the surf drops off. There’s a bit of a gap. We get some decent conditions on Monday the 10th of August with glassy conditions and a clean 4ft swell from the SW – that’s a nice novelty, but the energy is down (503). The real lull hits after the 10th. From the 11th through to the 13th, we’ve got small, weak swell and strong winds battering the place.
The tail end of the outlook has a couple of glassy moments worth noting. On Friday the 14th of August, the afternoon goes glassy with a 4ft SW swell (640 energy). Then Saturday the 15th of August afternoon, same story – glassy, 4ft from the SW, and the energy bumps up a bit to 821. These are mellow, clean sessions for the longboard or a funboard, but nowhere near the punch of that Wednesday-Thursday window.
That Wednesday the 5th and Thursday the 6th of August are your true standouts. Get on it.
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.
