The Lowdown
Right, let’s have a look at what’s on offer for the next couple of weeks. We’ve only got one spot lighting up the forecast and that’s the Dunes, a reef set-up that’s pretty consistent. The water temp is sitting about average for this time of year, so nothing weird going on there.
The first real bit of hope shows up on Saturday the 7th in the morning. The swell will be 5ft from the SW, with a 13-second period, and we’ve got a fresh offshore breeze from the SSE. It’s a solid, clean start to the day, but it’s right on the edge of being a bit punchy for beginners. The combined energy is moderate (1135). After that, it gets a bit messy with the wind swinging around.
Now, the standout session, and I mean the one you’d circle on the calendar, is Saturday the 12th in the morning. That’s over a week away, so we’re in long-range territory, but it’s looking promising. The swell picks up to 5ft from the WSW, but the period blows out to 18 seconds – that’s proper groundswell, long lines. And the wind? Glassy. Dead flat. The combined energy is strong (1434) and the conditions are flagged as excellent for experienced surfers. That’s the one. The reef should handle that long-period energy beautifully.
Before that, Thursday the 11th morning also looks clean with glassy conditions, but the swell is smaller at 3ft and the period is 14 seconds. It’s a fun, clean option for a quiet paddle.
Going further out, Monday the 14th morning has a bigger pulse of 6ft from the WSW, 16-second period, and a light cross-off breeze. The combined energy is strong (1684). That’s another one for the experienced crew, as it’s over the 5ft mark. The wind holds clean. But remember, that’s still a week and a half away.
The very end of the run, Saturday the 19th and Sunday the 20th, shows some proper size – 7ft from the SW and WSW, with solid periods. On Saturday afternoon, it’s got a cross-shore wind and the combined energy is very strong (3352), but the notes say it’s likely too big for this break. Sunday morning the 20th has a clean offshore breeze from the SE with that same 7ft swell and very strong energy (2502), but again, it’s expert territory only. If you’re a charger, those last days could be wild, but for most of us, the Saturday the 12th glassy session is the pick of the bunch.

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.
