The Lowdown
Howdy, Rusty here again. Let’s look at what’s on offer at Dunes reef break over the next couple of weeks.
The story is a consistent SW groundswell, but the wind is gonna be a headache a lot of the time. Lots of lumpy cross-shore chop will be spoiling the fun on most afternoons. The water temp is about 75°, which is just normal for the year.
The first real chance to get a clean one is Wednesday the 16th morning. Light SSE offshore breeze, 10 mph, keeping things tidy. We’ve got a steady 4ft of SW swell with a long 14-second period. The energy is moderate, coming in at 663. It’s not massive, but clean lines will be there. Next up, Thursday the 17th morning goes totally glassy with a 5 mph SE breeze. The swell drops a bit to 3ft from the WSW, but for Dunes, glassy is what we dream about.
Now, the big one. Saturday the 19th morning is the real standout. A solid 7ft of WSW groundswell with a very long 16-second period. The energy is strong, hitting 2008. That’s a lot of power. A moderate 15 mph SSE offshore breeze will keep it clean, but this one is for advanced surfers only. It’s going to be heavy and powerful. Crowds are possible at this spot, and a wave like this will definitely draw a crowd.
The following Saturday, the 26th morning, has another decent push. We get 5ft of SW groundswell with that very long 17-second period again, and energy over 1600. Moderate S cross-off wind keeps it clean, making it another worthwhile early session.
You can find a few smaller, clean windows on mornings like the 24th and the 30th with waist-high waves, but the onshore and cross-shore winds wreck the afternoons consistently. After the 19th, it’s a long stretch of messy afternoons, so get out early.
The 27th and 28th? Forget it. The wind goes cross-on and straight onshore from the west and northwest, and the swell fades with it. There are gaps of flat and messy days between the clean windows, so plan your sessions wisely.
If you have to pick: Wednesday the 16th morning for fun, clean conditions, or circle Saturday the 19th morning for the real deal – big, clean, and powerful, but strictly for the experienced.
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.
