The Lowdown
Alright, this is Rusty here, and I’ve been staring at the charts for the next couple of weeks. Let’s get into it.
We’ve got one spot on the menu for the next 16 days, and it’s Dunes. This is a reef break, and it’s a consistent one, so it’s offering us something to work with from the get-go. The water’s sitting at 75°, right about average for this time of year, so nothing unusual there.
The first real chance to get wet is Monday morning, July 27th. It’s small, with a 2ft swell from the WSW, but the wind is offshore from the SE at 12 mph. That’s going to make it clean, even if the waves are ordinary. The combined energy is weak (175). Monday afternoon is a write-off with a cross-shore, so don’t bother.
Tuesday morning, the 28th, is a bit better. Still small at 3ft from the SW, but the wind is a cross-offshore from the E at 9 mph, and it’s clean. Combined energy is moderate (253). This is a solid enough window for a small-wave session.
The real standout is Saturday morning, August 1st. The swell bumps up to 4ft from the SW, with a 16-second period. That’s a long-period groundswell. The wind is offshore from the SE at 9 mph, keeping it clean. The combined energy is strong (692). This is the best call of the first week. Just be aware, crowds are possible here, so get in early.
We’ve got a bit of a gap after that, but the next promising window is Wednesday morning, August 5th. The swell size is 4ft from the SW, with a 17-second period, giving it a very long period feel. The wind is a cross-offshore from the S at 9 mph. Combined energy is very strong (953). This is another standout, but it’s a week away, so keep an eye on it.
The second week has a few more options. Sunday afternoon, August 9th, is looking good with 4ft from the SW, a 15-second period, and a light cross-offshore breeze. It’s clean and the energy is strong (680). Then, Tuesday afternoon, August 11th, is the last one I’d circle. The swell is 5ft from the SW, with an 11-second period, and the wind is a cross-offshore from the S at 9 mph. The combined energy is very strong (882). This one is going to have some punch, so it’s for the more experienced crew.
Overall, the best on offer is Saturday morning, August 1st, and Wednesday morning, August 5th. That first Saturday is the one to aim for right now. The rest of the time is a mix of small, clean, or marginal conditions. Keep your eyes on the charts, because things can change.
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.
