The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Dunes.
Alright, we’ve got a bit of a mixed bag coming our way over the next couple of weeks at Dunes. There’s some proper energy in the water for the experienced crew, but you’re going to have to pick your windows carefully, especially with the wind. The water temp is about average for this time of year, nothing unusual there.
We kick off on Monday the 7th with a clean but marginal surf. Swell is coming in at 5ft from the SW with a solid 13-second period, packing a punch with combined energy of 1271 (strong). Problem is, the wind is a cross-off from the SSE at 16 mph. It’s not terrible, but the conditions are holding it back from being great. The afternoon stays similar with a touch less size at 5ft.
Tuesday the 8th sees the swell dip a little to 4ft, but that period jumps to a very long 16 seconds – proper groundswell. The morning has clean, moderate offshore wind from the SE at 16 mph. For a reef break, that long period could make things a bit straight, but with the wind angle, it could be worth a look for the patient surfer. The energy is moderate at 886.
Wednesday the 9th morning looks like the first real standout. You’ve got that same 4ft SW groundswell with a 16-second period, combined energy at 851 (moderate), and a clean offshore wind from the ESE at 16 mph. Conditions are set for some very good surf. This is your pick of the early week for sure. The afternoon turns onshore though, so get out early.
The rest of the week into the weekend gets messy. Thursday the 10th is all cross-onshore and onshore wind, with the swell shifting to the WSW. The surf quality drops right off. Friday the 11th is even smaller and poorer – barely worth a look.
Now, here’s the next real highlight. Saturday the 12th morning delivers. The swell is 4ft from the WSW, but the period is a very long 18 seconds, and the combined energy jumps to 1378 (strong). The wind is a clean cross-off from the S at 9 mph, which is gentle. The report says excellent for experienced surfers. That’s your absolute standout window for the whole forecast. The afternoon gets a bit choppy with a cross-shore wind, but the morning session is where it’s at.
Sunday the 13th morning is still decent with 5ft from the WSW and a 15-second period, cross-off wind, and clean conditions, but the energy is lower at 1014 (strong). A solid option, but not quite the peak of Saturday.
The following week (from Monday the 14th onwards) is a bit more of a waiting game. There’s a mix of cleaner mornings with moderate offshore winds and some choppy afternoons. The standout there is Wednesday the 16th morning – 4ft from the SW, 14-second period, and a clean offshore wind from the SSE. Not huge, but it’ll be clean. There’s also a pulse of swell arriving on the morning of Tuesday the 22nd, with 6ft from the SW and a 16-second period, combined energy of 1582 (strong), with clean cross-off wind – that one looks promising but it’s a long way off, so keep an eye on it.
Crowds at Dunes can be an issue sometimes, so for the best windows, especially that Saturday morning, get in early.
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.
