The Lowdown
G'day, it's Rusty. Look, I'm not gonna lie, we've got a bit of a wait on our hands for anything decent. The first few days are a write-off, so don't bother paddling out just yet. The good news is, once we get to the middle of the week, the swell window opens up and we get a proper taste of winter.
The first real standout is shaping up for Wednesday the 5th of August. The morning is where it's at. We're looking at Dunes – a consistent reef break that's exposed to the south-west. The swell is swinging in at 5ft from the SW, with a long period of 17 seconds giving it plenty of push. The combined energy is a solid 1041 (moderate to strong), so there's a decent amount of power in the water. The wind is light and offshore from the ESE, which will keep it clean. This is intermediate territory, but that size and power will be a bit much for beginners. The water temp is sitting at 75°F, which is about normal for this time of year.
Thursday the 6th of August looks even better for the experienced crew. The morning at Dunes has a 5ft SW swell, still with a 16 second period and an even stronger combined energy of 1158 (strong). The wind is light and offshore again from the SE, so it will be glassy and clean. This is proper expert territory, so if you're not confident, watch from the sand.
There's a fun little window on Sunday the 9th of August morning. The swell has dropped to 4ft from the SW, still with a long period of 15 seconds, and the wind is a fresh offshore from the SE, giving us clean, lined-up waves. The energy is 779 (moderate).
After that, the swell backs off for a while. The second week looks quieter, but the last day of the forecast period is worth a mention. On Sunday the 16th of August, the afternoon session at Dunes looks glassy. The swell is a modest 3ft from the SW, but with a very long period of 18 seconds and glassy conditions (NE wind at 3 mph), it could be a beautiful, clean end to the week. The energy is 863 (moderate).
Don't bother with the rest of the time; it's mostly onshore or too small. Keep your eye on Wednesday the 5th and Thursday the 6th.
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.
