The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a slow start on the whole, but things are looking up later. The first few days are nothing to write home about, with only small, marginal surf on offer. The real standout is going to be that Sunday morning on the 30th of July, and the following Friday morning on the 31st of July – those are the ones to circle. The water temperature is sitting at 76°, which is about 1° warmer than what’s normal for this time of year, so nothing wild there, just a touch warm.
Right now, Dunes is the only game in town. It’s a consistent reef break, exposed to the SW swell, which is exactly what we need. The best bet for a session is going to be Monday morning, the 20th of July. We’ve got a clean 4 ft SW swell rolling in with a 14-second period, a light offshore breeze from the SE, and the combined energy is sitting at a solid 586 (moderate). It’s not huge, but it’ll be clean and fun. Crowds are possible here, so get in early.
The following weekend, around the 26th and 27th, things drop right off. We’re looking at tiny, poor surf for a stretch of about four days straight. A blank run, basically. The swell picks up again on the 30th of July, Thursday morning. We see a 4 ft SW swell with a very long period of 18 seconds, and the combined energy jumps to 1083 (strong). That’s a real groundswell, and it’ll be clean with a cross-off breeze. But remember, that long period can make a beach break a bit too straight, but Dunes is a reef, so it should handle it well.
The true standout is the 31st of July, Friday morning. That’s for the experienced crew. We’ve got a 5 ft SW swell with a 17-second period, a clean offshore wind from the SE, and the combined energy is strong at 1101. The call is for excellent surf conditions, but it’s one for the experts as the swell is solid. After that, the first of August has a smaller, cleaner 4 ft SW swell, but it’s not as good as the day before.
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.
