The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, it’s a bit of a mixed bag for the next couple of weeks. We’ve got a consistent, long-period SW groundswell running through the whole period, but the wind is going to be our biggest enemy most days. The best action is definitely going to be in the mornings, and we’ve got one standout session that’s really worth setting the alarm for.
The first few days, from Tuesday the 8th through to Friday the 11th, are pretty average. Dunes is getting a clean, 4ft swell from the SW with a long 16-second period, but the wind is either side-shore or onshore, messing up the face. The water is sitting at 74°, which is pretty normal for this time of year. The combined energy is moderate, but the conditions just aren’t there. It’s a bit of a frustrating start.
Then we hit Saturday the 12th of September, and that’s the one. Early morning, the wind drops right out to a slight SSE breeze, going cross-offshore. The swell is 4ft from the WSW with a very long 18-second period, pumping a solid combined energy. This is a classic setup for a reef break like Dunes – long, clean lines with plenty of power. It’s going to be a proper session for experienced surfers. The wind stays clean all morning, so get out there early. The afternoon gets a bit lumpy with a strong cross-shore, so the morning is the window.
Sunday the 13th and Monday the 14th are okay if you’re desperate, with clean mornings and 4ft to 5ft swell, but the energy drops off a bit and the wind starts to get stronger again through the afternoons.
From Tuesday the 15th right through to the end of the first week, the afternoons are a write-off with strong, messy cross-shore winds. The mornings remain clean but the swell quality is just marginal. It’s a real grind.
Looking into the second week, there’s a glimmer of hope. On Saturday the 19th of September, the morning looks clean again with a 5ft SW swell and a cross-offshore breeze. The energy is moderate, and it’s a solid 15-second period. It’s not the standout of the 12th, but it’s a decent option if you missed the window.
The very end of the forecast, on the morning of Monday the 21st of September, shows a drop in swell to 3ft, but the wind is light and clean. Then on the morning of Tuesday the 22nd, we see a 3ft swell with a 16-second period and a clean cross-offshore breeze, but the energy is still moderate.
So, to wrap it up: the absolute best bet is Saturday the 12th of September, early morning at Dunes. That’s the one you don’t want to miss. Everything else is a case of picking the clean morning windows for a session that’s more about being in the water than scoring perfection.
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.
