The Lowdown

Alright, Rusty here. Let's talk about what's coming up.

Right now, the surf looks a bit slow to start, but we’ve got some decent windows over the next couple of weeks. The first real action kicks off on Friday morning, the 31st of July, at Dunes, a consistent reef break that's exposed to the SW swell. The water's sitting at about 75°, which is pretty much average for this time of year, so no surprises there.

We've got a long-period groundswell pushing in from the SW at 3 ft with a 16-second period, which gives it some real grunt. Combined swell energy is solid at 383, and with a light offshore breeze from the SE at 15 mph, it’s going to be clean and lined up. This is a good, solid session for intermediates.

The standout of the whole forecast, though, has to be Saturday morning, the 1st of August. The swell picks up to 4 ft from the SW, still with a long 16-second period, and the energy jumps to 657. The wind is offshore from the SE again at 12 mph, and the call for 'very good surf conditions' is proper. You'll want to be in the water early for that one.

After that, the middle of the first week gets a bit mixed with lighter swells and more cross-shore winds, but the morning of Tuesday, the 4th of August, has potential. It’s a cleaner 3 ft SW swell, and the wind drops to almost nothing from the ESE at 3 mph. That's about as glassy as it gets, so the waves will be smooth and forgiving.

Looking further out, the week of the 6th of August has some solid pulses. Thursday the 6th morning looks promising with a 4 ft SW swell, clean conditions, and light winds. Then Saturday the 8th afternoon shows a bigger bump to 6 ft from the SW with a very long 17-second period, and the combined energy is a hefty 1735. That's a lot of water moving, so it'll be powerful, but the winds are strong and cross-off, which could make it tricky. That's one for confident surfers only.

The true highlight comes at the end of the run. Friday afternoon, the 14th of August, at Dunes, is where you want to be. We're looking at a consistent 5 ft SW groundswell with a 17-second period, the combined energy is a massive 1545, and the wind is a light SSW cross-off at just 3 mph. The description says 'excellent surf conditions for experienced surfers', and I’m calling that the best of the bunch. It’s a fair way out, so keep an eye on it, but it has all the right ingredients.

Overall, there are a few gaps with weaker, less clean surf, but there are enough decent mornings and that final Friday standout to make the next couple of weeks interesting.

Stay stoked, catch you in the water.

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.
