The Lowdown
Alright, Rusty here, checkin’ in with the local outlook for Dunes.
Right off the bat, the next week and a half is gonna be a real grind. We’re lookin’ at a solid stretch of frustrating conditions from now through the start of August. The wind is mostly a problem—fresh easterly breezes keep things cross-off, but the swell is just too small and weak to do anything with it. You’ll see waves around 1ft to 3ft, and the energy is weak to moderate (139 to 667). The water’s sitting at 76°F, which is about average for this time of year.
The real story starts to shift around Wednesday, July 30th, when the swell energy starts to climb a bit. By Thursday, July 30th morning, we’ve got a 3ft SW swell with a period of 17 seconds, and the energy is strong (520). The wind is still cross-off from the east, so the surface is clean. The quality is still just marginal, but it’s a glimmer.
The real standout, the one you’ve been waiting for, is Wednesday, August 5th, in the morning. This is the best on offer. We’ve got a 4ft SW groundswell, 13 second period, and the wind is light and variable from the south—basically glassy, cross-off conditions. The water will be clean, and the wave forecast says “expect very good surf conditions.” The energy is moderate (567), but the quality is what counts. Dunes is a consistent reef break, so it handles that long-period energy well. Keep in mind, with the swell direction from the SW matching the optimum, this break will be firing.
A couple days later, on Friday, August 7th morning, there’s another decent window. A 4ft SW swell with a 15-second period, and a light SSW cross-off wind. Again, clean conditions and “very good surf conditions” forecast. The energy is moderate (748). This is your second-best option for the run.
For the rest of the period, especially around August 4th, the swell jumps up to 6ft with a short period of 14 seconds, but the wind is cross-onshore and choppy. That’s just a messy, blown-out mess—not for paddle surfing. If you’re into kiting, that setup might look more interesting.
So, to sum it up: grind through the first week, keep your eye on the 5th of August morning, and then the 7th of August morning as a solid backup. The water temp is about average, and the crowds at Dunes can be around sometimes, so get there early for the good ones.
Rusty, out.

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.
