The Lowdown
Alright folks, Rusty here. Let’s get into the Dunes forecast.
Water temp is about 75°F, which is normal for the season.
The first few days are a bit shaky. Thursday the 30th and Friday the 31st are nothing to write home about. The swell is there at 2-3ft from the SW, but the wind is shifty. Friday morning, though, you get a clean offshore breeze from the ESE at 9 mph, making for some tidy little waves. It’s small, but clean.
Then Saturday the 1st of August wakes up. You’ve got 3-4ft of SW swell with a 16-second period and a solid 12 mph SE offshore. The wave energy is strong. That’s a proper day for the reef. The crowd factor is ‘sometimes’ a problem, so plan accordingly.
Sunday and Monday lose the plot a bit with wind and dropping swell periods.
Now, mark your calendar for Wednesday the 5th of August. That’s the one. Light offshore wind, and the swell builds to a solid 4-5ft from the SW with a 17-second period. The energy is huge. That’s groundswell, and it will have the reef working. It’s listed as excellent for experienced surfers, and that’s no lie.
The second week gets heavy. Thursday the 13th of August is looking at a massive 10ft SW groundswell. The report flags it as too big for this break, and I can’t argue. That’s a lot of ocean moving around. Friday the 14th is still oversized at 7ft. The 12th might offer some clean 2-3ft waves with light winds, but the real size after that is for the experts or the kite surfers.
So, for the paddle crew, your windows are Saturday morning and, most importantly, Wednesday the 5th.
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.
