The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming up for Dunes.

First thing to say, the next week and a half is pretty quiet. We’ve got tiny swell and mostly cross-off winds, but the models are calling it poor surf conditions right through to the end of July. The combined energy is weak, sitting between 139 and 444, so don’t expect much push. The water temp is sitting at 76°, which is about average for this time of year, nothing weird there.

The first real sign of life shows up on the morning of Friday, 31 July. The wind swings offshore from the ESE at 6 mph, the swell picks up to 3 ft from the SW with a 16-second period, and the energy jumps to 533. That’s a moderate energy groundswell, and the conditions are clean. That afternoon gets even better – glassy conditions, 2 ft of SW swell with an 18-second period, and energy hitting 560. This is the kind of session where you’ll feel like you’ve got the place to yourself if the crowds aren’t too bad. Crowds are possible at Dunes, but on a Friday it might be manageable.

Then Saturday, 1 August, morning is the standout. Offshore breeze from the SE at 12 mph, 3 ft of SW swell, 16-second period, and the energy is up to 725. That’s moderate but getting meaty. The waves will be clean, lined up, and the long period means the sets will be well-spaced, making it easier to get out the back. This is the best on offer in the whole outlook – a proper clean groundswell with favourable wind. The afternoon turns onshore, so make the most of the morning.

The following week, 8 August, Saturday morning, we see a bigger pulse: 6 ft from the WSW, 16-second period, offshore from the SSE at 9 mph, and energy at 1590. That’s strong wave energy. The break is a reef, so this size will be handling it well, but it’s pushing into expert territory. The afternoon is too big at 7 ft for this spot, so only the brave would be out there.

Overall, the best windows are Friday 31 July morning through to Saturday 1 August morning, and then Saturday 8 August morning for the bigger stuff if you’ve got the skills. Crowds are a possibility, but the quality will be worth it.

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.
