The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Dunes.
Overall, it’s a mixed bag over the next couple of weeks. There’s always a bit of swell rollin’ in, but the wind is the real story here, and it’s gonna cause more trouble than it’s worth for a lot of the time. There are a few absolute gems tucked in there though. The first decent window is gonna be Monday the 7th.
Monday, September 7th, the morning is looking like a proper start. We’ve got a solid 4ft SW swell with a fresh offshore wind from the SE, so that south-west groundswell is gonna be cleaned right up (combined energy is 931 – moderate). That offshore flow is a winner. The afternoon sees the swell drop back a little, but it’s still a clean 3ft with long, tasty 17-second periods (1082 – moderate energy). Sets will be few but fat. This is the best of the first week.
Tuesday, September 8th is more of the same vibe – 4ft SW swell in the morning with that fresh offshore, so it’ll be clean and lined up.
Then we hit a bit of a lull in quality until Thursday, September 10th. That morning is a standout. The swell is a touch bigger at 4ft from the WSW, and the wind has dropped to a total glass-off – 5 km/h from the NNE (753 – moderate energy). It doesn’t get much better than a glassy October morning with consistent groundswell. You want to be out there. Friday the 11th morning is also glassy, with a 3ft WSW swell – also a great call for smooth conditions.
Further out, Sunday, September 13th morning is the big one. Swell jumps to 5ft from the WSW with a gentle offshore breeze from the ESE (1056 – strong energy). This is setup for excellent conditions for experienced surfers. Don’t be a beginner on this day; the size and the long period (15 sec) will push the limits, but it’ll be incredible for those who can handle it. The combined energy (1056) is strong, backing that up.
Tuesday, September 15th is another one to circle. The morning bumps up to 5ft from the SW, but the wind is more cross-shore (1251 – strong energy). It’s still rideable for the skilled crew, but not the pristine conditions of the 13th. Following that, Wednesday, September 16th morning swings back to glassy conditions with a 3ft WSW swell – a clean little session.
After that, the last proper window looks like Friday, September 18th morning, with a glassy 3ft WSW swell. A small, clean day to finish the run.
There are a lot of afternoons written off by strong onshore or cross-shore winds, and some mornings are just marginal. The water temp here is currently around 74°F, which is pretty much average for this time of year – nothing unusual.
The clear best day in the whole window is the morning of Sunday the 13th for the strong swell and offshore breeze, with the glassy mornings of the 10th and 11th being the best bets for cleaner, smaller waves.
Stay stoked,
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.
