The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s shaking at Dunes over the next stretch.

It’s a slow start, but there’s a real gem hiding in there if we’re patient. The first few days are a bit of a washout – small, messy, and choppy with cross-shore winds. The water temp is 75°, which is about normal for this time of year.

The first real chance to get wet comes on Monday, the 24th of August, in the morning. We’ve got a 3ft SW swell with a long 16-second period, and the wind is offshore. It’s not a big one, but the energy is moderate (652) and the conditions will be clean.

The absolute standout, the one you don’t want to miss, is the morning of Thursday, the 27th of August. The wind is pumping offshore from the SSE at 25 mph, and we’ve got a solid 7ft swell from the WSW with a long 17-second period. That’s a massive amount of energy (2323), and it’s going to be clean. This is a powerful, long-period groundswell. A word to the wise: this is a big wave with a long period, so it’s for experienced surfers only. The offshore wind is strong, so paddling in will be a workout, but if you can handle it, it’s going to be world-class. The water will be glassy, but the power is real.

The Thursday afternoon (27th) is still very good, with a 6ft swell and clean cross-offshore winds, but the morning is the winner.

After that, things settle down. We get a few more clean mornings with smaller swell, but nothing that jumps out. Then, on the morning of Tuesday, the 1st of September, we see another pulse of solid 6ft WSW swell, but the wind is cross-offshore, so it’s not as perfect as the 27th. The energy is still strong (1720), but the wind is a little less ideal.

The best of the second week looks like Wednesday morning, the 2nd of September. The wind is light and cross-offshore, and we’ve got a 5ft WSW swell with a 15-second period. The energy is moderate (1005), and the conditions are clean. This is a solid, fun day for experienced surfers, but it’s a smaller version of the 27th.

Also keep an eye on Thursday morning, the 3rd of September. The wind is glassy, and the swell is 5ft from the WSW. It’s a smaller day, but with glassy conditions it’s one of the best-looking waves for a less hectic session.

So, the bottom line: the first few days are a dud. The best on offer is the morning of Thursday, the 27th of August, with a big, powerful, and clean swell. The second best is the morning of Tuesday, the 1st, and Wednesday morning, the 2nd of September.

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.
