The Lowdown
G'day, Rusty here, looking at the forecast for Dunes over the next couple of weeks.
Alright, the first week is a bit of a mixed bag, but we've got some real promise on the horizon. The water temp is sitting at a warm 75°, which is pretty much spot on for this time of year, so no surprises there.
The weekend kicks off with a bit of a whimper. Saturday morning (22 August) has a 4ft SW swell, but it's coming in with a light cross-onshore breeze, so it's not going to be anything special. The afternoon gets worse with a fresh cross-shore wind and a similar-sized swell, so I'd give it a miss. The combined swell energy is moderate at 671.
Sunday (23 August) is a bit cleaner with a cross-offshore wind, but the swell drops to 4ft, and the energy is still moderate (517). It's rideable, but nothing to get excited about.
Then Monday (24 August) morning shows some real potential. We've got a clean, moderate offshore wind from the SE with a 3ft WSW swell. The swell period is a long 16 seconds, which means groundswell with good shape and energy. The combined energy is a solid 733. This is the pick of the first week for a clean, fun session.
The end of the week, Thursday (27 August), is a big one but only for the experienced crew. We're looking at a 6ft SW swell with a 17-second period, which is very long. The combined energy is strong at 1834. The morning wind is a strong offshore breeze from the SSE, which will keep it clean, but that size and power means it's a paddling mission and strictly for the experts. The afternoon is also 6ft with a fresh cross-offshore wind, also clean.
Now, if you can wait, the real standout is the following Monday morning, 31 August. We've got a 5ft WSW swell with a huge 19-second period, and the combined energy is a very strong 1806. The wind is dead calm, just a slight air, and it's a clean offshore. This is an excellent surf forecast for experienced surfers.
And that Tuesday morning, 1 September, is nearly as good. Another 6ft WSW swell, 17-second period, still strong energy at 1599, and again, glassy conditions with a slight offshore breeze. That's two mornings in a row of proper, world-class potential.
The second week has a few more decent, smaller windows. The morning of Saturday 5 September has a 4ft SW swell with a long 17-second period and barely a breath of wind, just a slight air. The energy is moderate (688), and it's a very clean option for a relaxed session.
So, to sum it up: the first week is mostly a waiting game, with Monday 24 August morning being the best of the early period. But the real magic is happening on Monday 31 August and Tuesday 1 September mornings. Those are the absolute standouts. Get the dates in your diary.
Rusty, signing off.

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.
