The Lowdown
Alright, grab your board and let’s get into it. The next couple of weeks at Dunes are a bit of a mixed bag, but there are definitely some windows where it's gonna light up. We’ve got a slow start, but hold tight because the middle of the run has some proper juice, and the very end is looking tasty too.
Right now, it’s pretty average. Friday afternoon sees a modest 3ft SW swell rolling in, but a cross-on breeze is gonna chop it up, so it ain't worth paddling out for. The water temp is sitting at 73°, which is right on the money for this time of year, nothing weird going on there.
Saturday morning, though, is where it starts to get interesting. The wind drops to nothing, the ocean goes glassy, and that same 3ft SW swell is still there. The energy is moderate (468), and it’ll be clean. It’s not big, but it’s a fun one. Sunday morning is similar, slightly smaller at 3ft but still glassy and clean.
Then the swell starts to build. Monday sees it jump to 5ft from the SW. The morning gets messy with a cross-shore wind, but the afternoon cleans right up with a cross-off breeze. That energy is climbing into the moderate-to-strong range (1055), and it’s looking much better.
But the real standout is Tuesday the 18th. The swell pushes up to 6ft from the WSW, with a solid 17-second period. That’s proper groundswell, and with a gentle offshore wind in the morning, it’s going to be firing. The energy is strong (1570) and conditions are set to be excellent for experienced surfers. This is the one to circle on the calendar. The afternoon swell gets even bigger, hitting 7ft, but that might be pushing it for this spot – it could be too much for a lot of folks.
Wednesday morning (the 19th) is also good for experts. Another 7ft of WSW swell with a moderate offshore wind, keeping things clean. Again, this is big, powerful surf – not for the faint of heart. The energy is through the roof at 2450.
Things back off a bit from Thursday the 20th through to the weekend, with waves in the 4ft to 5ft range. The mornings are generally cleaner, with lighter winds. Friday morning on the 21st looks pretty nice – 5ft with a cross-off breeze and clean conditions. Then we hit a bit of a lull for a few days, with smaller surf and mixed winds.
The next real standout is way out there, on Tuesday the 26th of August. It’s a long-range call, so don’t book your flights yet, but the models are showing another pulse of 6ft SW swell with a moderate offshore wind. It’s got a good chance of being excellent for experienced surfers, but it’s a week and a half away, so treat it as promising, not guaranteed.
Finally, we end the run with a couple of fun mornings. Friday the 28th has 4ft with a clean cross-off breeze, and Saturday the 29th has a longer-period 3ft WSW swell, but the wind might be a bit more on it. Overall, if you can get out for Tuesday the 18th, that’s your pick of the bunch. The week after has a couple of clean mornings, but the real juice is that mid-period push.
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.
