The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Dunes. This spot is a consistent reef break that handles a good SW swell, and the water is sitting at 75°F, which is pretty normal for this time of year.

The first real action we see is on Wednesday morning, the 19th. We’ve got a solid 7ft WSW swell running with a very long period of 16 seconds, and the combined energy is strong at 2234. That’s a lot of power. The wind is offshore from the SE at 12 mph, so the waves will be clean. But, and it’s a big but, 7ft is getting into the territory where this reef could be too big for most. It’s a real standout session for experienced surfers only, and the long period means it’ll be lining up nicely, but with big gaps between sets. If you’re not on it, it’s a serious paddle.

If that Wednesday morning swell is too much, the pick of the week might be the following Thursday morning, the 20th. The swell drops to a more manageable 4ft from the WSW, still a nice 14-second period, and the energy is moderate at 1020. With the SE wind at 12 mph, it’s clean offshore. This is another excellent call for experienced surfers, and the conditions will be much more forgiving.

The rest of the week is a mixed bag. Friday morning the 21st has a fresh offshore breeze, but the swell is a bit small at 5ft, and the energy is weaker at 894. It’s okay, but nothing special. Saturday morning the 22nd offers a gentle offshore with a 4ft SW swell, but the energy is dropping to 669. It’s surfable, but nothing to get excited about.

There’s a bit of a lull from Sunday the 23rd through to Tuesday the 25th, with small waves and poor conditions in the afternoons. Not worth the paddle.

Looking further ahead, we get a bit of a pulse again. Thursday morning the 27th sees a 6ft WSW swell with a long 16-second period and strong energy of 1720. The wind is cross-off from the SSE, so it’s clean. That’s a solid option for the experienced crew, but keep an eye on the tide.

The real standout of the entire forecast, though, is the first week of September. Tuesday morning the 1st of September is looking like a beast. We’re talking a 7ft WSW swell, a 16-second period, and very strong energy at 2506. The wind is a fresh offshore from the SE at 19 mph. This is a proper, powerful groundswell and it’s going to be clean. Again, this is expert territory only. It’s big, it’s powerful, and the reef will be doing its thing. If you’ve got the skills, the experience, and the respect for the ocean, that’s the session to aim for, but it’s a long way off so keep your fingers crossed the forecast holds.

After that, the swell backs off a bit into the 5ft to 6ft range for the rest of the first week of September, with a mix of clean and choppy conditions.

So, to sum it up: the best waves for the average surfer are the Thursday morning the 20th. For the big dog crew, mark your calendar for the morning of the 1st of September. Stay safe out there.

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.
