The Lowdown

Right, let’s have a look at what’s coming up for Dunes, a reef setup that’s exposed to the southwest. This place is consistent, and it's got a good run of surf ahead, but the wind is going to be the main character in this story. The water temperature is about average for the time of year, so nothing weird there.

The first real crack at it is Monday morning, August 24th. We’ve got a clean 3ft groundswell rolling in from the WSW with a very long 16 second period, and a light offshore breeze from the SE. That’s a gorgeous start to the week – the wave energy is moderate (652), and that clean, offshore wind will have Dunes looking like a postcard. This is the standout session of the whole forecast, no question.

That afternoon, the wind swings to a cross-shore from the WSW, and the swell picks up a touch to 4ft, but the period drops to 15 seconds. The energy is still moderate (666), but the wind is going to mess it up. It’s a miss.

Tuesday morning, the 25th, sees the swell settle to 4ft from the SW with a 13 second period, and we’re back to a clean offshore SE breeze. Good conditions, but the energy is down to 415. Not as special as Monday, but a solid option. Tuesday afternoon is a write-off with cross-onshore wind.

Wednesday morning the 26th is clean again with a light cross-offshore breeze and a 3ft swell from the SW. That’s a nice, manageable wave for intermediates, but the energy is still moderate (460). Thursday morning the 27th brings a bigger pulse: 6ft from the WSW with a 17 second period. That’s pushing into expert territory, and the energy jumps to 1997 (strong). The offshore wind from the SSE at 18 mph will keep it clean, but that’s a serious wave. Only for the experienced crew.

Friday morning the 28th is another clean morning with 5ft swell from the SW, but the offshore wind is a fresh 18 mph, so it’ll be a bit of a battle to get out there. Still, the wave energy is moderate (857). The weekend is a bit of a mixed bag. Saturday morning the 29th has a bit of a drop-off to 3ft, and the wind is cross-offshore, so it’s clean but small. Sunday the 30th is a write-off, with poor conditions.

Now, look ahead to Monday August 31st. There’s a 4ft swell from the SW with a 16 second period, but the wind is cross-offshore from the ENE at 22 mph. The energy is strong (1171), but that wind is going to make it a bit bumpy. Not ideal.

The best of the second week looks like Thursday September 3rd. Morning session has a 4ft swell from the WSW with a 14 second period, and a gentle offshore breeze from the SE. That’s clean, glassy, and the energy is moderate (557). That’s a very good morning. Then Saturday September 5th morning is also a contender: 4ft from the SW, 13 seconds, and a moderate offshore SE breeze. Another clean, solid session.

And then Monday September 7th morning rounds it out with another 4ft, 14 second SW swell and a gentle offshore breeze. The pattern holds.

Overall, the standout is absolutely Monday morning, August 24th. That clean, long-period groundswell with the offshore wind is the best wave you’ll see in this run. The other good mornings are Tuesday the 25th, Thursday the 27th (for experts only), Friday the 28th, Saturday the 5th, and Monday the 7th. The afternoons are mostly a no-go due to wind. The breaks in quality are about a day and a half, here and there, but there’s plenty to work with if you’re keen on the early sessions.

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.
