The Lowdown

G'day, it's Rusty here. Alright, we've got a bit of a mixed bag coming up at Dunes, but let's get into it. The good news is there's a solid SW groundswell running through the whole period, but the timing and wind are going to be the real story.

The first real chance for a decent paddle comes Sunday morning, the 9th of August. We're looking at a clean 5ft set from the SW with a 14-second period, but the wind is howling out of the SE at 22 mph, which is offshore and clean. That's a proper session for the experienced crew. The combined energy is moderate (1111). The water is sitting at a pleasant 75°, which is pretty much normal for this time of year.

Now, if you can wait, the standout window is Wednesday afternoon, the 12th of August. The wind drops to a staggering 3 mph from the north, leaving it glassy. The swell is still a clean 4ft from the SW with a long 16-second period, packing moderate energy (721). This is a reef break, so that long period groundswell will groom into some proper lines. It's a consistent spot, so you won't be sitting there waiting forever, but it can get crowded sometimes, so get in early.

The following week, there's a couple of other calls worth a look. Thursday morning, the 20th of August, sees a clean 6ft SW swell with a 15-second period and a solid offshore wind from the SE at 12 mph. The combined energy is strong (1289), and the forecast is singing for experienced surfers. That's a big, powerful wave, so it's not for the faint-hearted. The 5ft+ size means it's a step up from beginner territory.

Overall, the best on offer is that glassy Wednesday afternoon session. It's a true stand-out for the quality. For the rest of the time, the wind is often cross-off or cross-onshore, keeping things a bit choppy or bumpy, but the swell is persistent. The second week has a few promising days, but as always, long-range calls are a bit more of a gamble.

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.
