The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what's on the cards for the next couple of weeks.
The outlook starts off a bit slow and lumpy, with the first few days not offering much that'll get the heart racing. We've got swell, but the winds are crossing it up and making things messy. It’s a classic case of waiting for the ocean to clean up its act.
We start seeing some promise on Monday the 7th of September. The morning is still a bit fresh with a 19 mph offshore, but the afternoon settles right down to a gentle cross-off breeze. That's when the surf at Dunes (reef) will start showing its face properly, with 3ft of SW swell and a long 17-second period. The energy is moderate (903), but it's the combination of a clean face and that long-period groundswell that will make it feel better than the size suggests. It’s not huge, but it'll be a fun, clean session.
The real standout, the one you circle on the calendar, is Saturday the 12th of September. The morning is looking proper. We’ve got 5ft of WSW swell with a 17-second period, creating some very strong wave energy (1557). The winds are light from the ESE, keeping it clean. This is the biggest, most powerful swell of the window and it’s groomed by gentle offshore winds. This is the day for experienced surfers to get stuck in. The afternoon sees it bump up to 6ft but the wind shifts onshore, so make sure you get your fill in the morning. The water temp is a warm 74°, around average for this time of year, so the rubber might not even be needed.
The following week sees the size back off a touch. We’re still looking at some decent 4ft SW swells, but the winds get a bit more variable. The mornings on the 16th and 17th of September look like they could be worth a paddle, with gentle breezes and clean conditions, but the energy drops off. It’s definitely a case of picking your windows and hoping the wind gods play nice.
Overall, the first week is a write-off for the most part, with the best surf waiting until that Saturday the 12th. Keep your eyes on that day; it’s the one with the most grunt and the cleanest conditions.
Keep it salty.

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.
