The Lowdown
Alright, Rusty here. Let’s break down what’s coming.
We’ve got just the one spot in the mix – Dunes. It’s a consistent reef break, open to the SW, and the next couple of weeks are going to have some clean windows, but also some chop to sit out.
The water’s sitting at 75°, which is about 2° warmer than average for this time of year. That’s a nice touch.
Sunday the 23rd is a no-go. There’s swell around 4ft from the SW with a 15-second period, but a fresh 30 km/h cross-off wind and moderate energy (514) make it a messy, choppy day. Leave it.
Monday the 24th morning is our first real chance. A clean 3ft WSW groundswell, period stretching to 16 seconds, with a moderate offshore breeze from the SSE at 25 km/h. The energy is moderate (652), and it’ll be clean. That’s a good morning.
Tuesday the 25th morning is also worthwhile. Another 4ft SW swell, 13-second period, with a clean offshore from the SE at 20 km/h. The energy drops a bit (419), but it’s still a fun, clean session.
The standout session is Thursday the 27th. The morning is going to be a ripper. We’re looking at a 7ft WSW groundswell with a very long 17-second period. The combined energy jumps to 2323 – that’s strong. The wind is a light cross-off from the SSW. This is excellent, but it’s big. At 7ft, this is for experienced surfers only. The power and the long period will make it a serious wave at the reef.
Friday the 28th morning is another good one. The swell drops to 4ft from the WSW, but the wind goes light offshore from the SE at just 5 km/h. Clean conditions and moderate energy (711) make for a very good session.
Sunday the 30th morning also looks clean. A 3ft SW groundswell, 16-second period, with a moderate cross-off breeze. The energy is moderate (743), but it’s a smaller day.
Into the second week, the windows get narrower. Tuesday the 1st of September and Wednesday the 2nd both have clean mornings with 5ft and 4ft WSW swells, but the wind is stronger and the energy is moderate. Not as crisp as the first week, but still a chance.
The big one to circle is Thursday the 27th morning. That’s the session for the experienced crew. Big, powerful, and clean.
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.
