The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way.

We’ve got a solid run of SW groundswell on the boards for Dunes, but it’s a bit of a slow burner at the start. The first few days are a write-off with messy winds and poor conditions, so don’t bother paddling out until we get some proper windows. Gotta be patient.

Monday the 27th of July morning is the first chance to get wet, with a clean 2ft swell from the WSW and a moderate offshore breeze from the ESE. It’s surfable, but nothing to write home about. The energy is still weak at 175, and the waves are pretty ordinary. The water temp is sitting at 75°, which is about average for this time of year.

Things start to get interesting on Friday the 31st of July. Morning sees a 3ft SW swell with a moderate offshore from the SE keeping it clean. The combined energy is building nicely at 383, and the period is a long 16 seconds. Then Friday afternoon turns it on – glassy conditions, with a 2ft SW groundswell and a period of 18 seconds. The energy jumps to 460, and it’s clean as a whistle. This is a real standout session for the intermediate crew.

But the best of the whole run? That’s Saturday the 1st of August morning. We’re looking at a 4ft SW swell with a 16-second period, combined energy of 580, and a moderate offshore breeze from the SE. The waves will have some real grunt to them, and the conditions will be pristine. It’s still within the intermediate zone, but it’s the pick of the bunch. The afternoon gets messy with a cross-onshore, so get on it early.

After that, there’s a few more decent windows. Monday the 3rd of August afternoon sees a clean 4ft SW swell with a moderate offshore, and the energy is 394. Then Tuesday the 4th of August afternoon turns glassy again with a 2ft, 17-second SW groundswell. That’s a sneaky good session for the longboarders.

Now, the big one to circle on your calendar is Friday the 7th of August morning. Glassy conditions, a 4ft SW swell with a 16-second period, and the combined energy hits 615. It’s a very good forecast, and the offshore wind is absent, leaving it perfectly clean. This is a top-tier morning for Dunes if you can get out. The afternoon onshore kills it a bit.

We finish the run with another promising morning on Monday the 10th of August. A 3ft SW swell, moderate offshore from the ESE, and energy of 526. That’s another solid session to aim for.

Overall, the first week is a bit of a tease, but the second half of the run—especially from the 31st of July through the 10th of August—has some absolute crackers. Keep your eyes on Friday the 7th of August morning for the best of the best.

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.
