The Lowdown
Alright, surfers, Rusty here. Let's talk about what we've got coming up at Dunes. It's a bit of a mixed bag, but there's a real glimmer of something special if you're patient.
The water temp is sitting at a comfortable 76°, which is pretty much spot on for this time of year, so no surprises there.
Right now, things are looking flat and messy. The first few days are a write-off with poor surf conditions and cross-off winds. The swell is tiny, under 3ft, and the energy is weak. It's not worth getting wet.
We'll see a slow build through the end of July and into the first week of August. The swell starts to push up towards 4ft to 5ft, and the energy starts climbing into the moderate range. The winds are still a problem though, mostly cross or cross-off, keeping things from getting clean. The morning of Tuesday the 4th of August finally shows a shift with clean offshore winds from the SSE, but the waves are still marginal, not really firing. This pattern of marginal, cleanish mornings continues through to Thursday the 6th of August.
Now, here's the standout. The real magic looks like it will happen on the morning of Sunday the 9th of August. We've got a solid 6ft swell from the SW with a very long period of 16 seconds. That's a serious groundswell, and the combined energy is pumping strong. The wind is light from the S, making for clean conditions. This is groundswell, so it'll be better-shaped and have more power, though it might be tricky at a beach break. For a reef or point, this will be world-class. This is definitely for experienced surfers only, as that wave size is above the beginner threshold.
The afternoon of the 9th sees the wind swing onshore, so the morning session is the absolute window to hit. That's the one to circle on your calendar.
Keep in mind, Dunes is a consistent break, so when it's on, it's usually worth the wait. But for the first week, you're better off finding something else to do.
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.
