The Lowdown

Alright folks, Rusty here, looking at the Dunes forecast. It’s a bit of a slow burn, but there’s some real magic on the horizon.

The immediate outlook is a bit average, but don’t write off the whole period. We’ve got a long-period, solid groundswell forecast to roll in, and the key is waiting for the right morning with the offshore ESE wind to line up. The water temp is sittin’ about average for this time of year, nothing wild there.

Let’s start with Thursday the 30th and Friday the 31st. Thursdays’ looking pretty weak with small 3ft SW swell. The morning has a clean-looking cross-off wind, but the energy is just not there yet with a combined energy of (422). Friday morning is better, with a gentle offshore ESE breeze cleaning up that same small 3ft, giving us some shape on the sets.

Saturday the 1st of August is where it starts to get interesting. The morning session is a real standout early on. A 4ft SW groundswell with a 16-second period, and a moderate offshore breeze from the ESE keeping it clean. The combined energy jumps up to (655), which is a solid moderate push. That’s a proper little window.

We hit a bit of a flat spot through Sunday the 2nd and Monday the 3rd. The swell drops back to 3ft and the period shortens, making things a bit weak and messy. The winds are mostly cross-off, which keeps the surface tidy, but it’s not gonna get the heart pumping.

Tuesday the 4th is a bit of a nothingburger, but Wednesday morning the 5th is a big one to circle. The swell bumps up to 4ft from the SW with a 17-second period, and we get a light offshore from the ESE. That’s a dreamy combo, with combined energy spiking to (933). This is our second standout—the wave quality is going to be excellent, with those long-period lines wrapping in.

Thursday morning the 6th holds onto that 4ft SW swell with a 16-second period, and a super light cross-off wind from the SSW keeps it looking pretty.

We get a bit of a lull again before the big event. There’s a small clean option on the morning of Saturday the 8th, but the real standout window begins Sunday morning the 9th. The swell jumps to 6ft from the WSW, with a moderate offshore wind from the SSE. The combined energy is a very solid (1085). That’s a proper window for experienced surfers looking for power, but it might be a bit much for beginners.

The forecast gets a bit more unstable towards the middle of the month with some onshore winds, but then we get a huge pulse. Wednesday morning the 12th looks promising with 5ft SW swell and a 17-second period. The wind is cross-off from the SSE, cleaning it up nicely with combined energy at (1519).

Now, for the big dog. Thursday morning the 13th of August is the absolute highlight. We’re looking at a 6ft SW groundswell with a very long 19-second period, and a moderate offshore wind from the SE. The combined energy is a massive (2612). This is a powerful, long-period groundswell that will pour into the Dunes. You’ll see long, clean walls with proper push. It’s getting into expert territory for size, so heads up. The afternoon session on the 13th is actually flagged as potentially too big for the break, with the swell predicted to hit 7ft.

Friday the 14th rounds it out with another 5ft SW swell and 17-second period, and a fresh offshore wind from the SE.

So, to wrap it up: the standout sessions are absolutely Saturday morning the 1st of August for a fun, clean 4ft SW swell, and Wednesday morning the 5th of August for the 4ft, 17-second groundswell with light offshore winds. But if you want the real power, you wait for Thursday morning the 13th of August and that 6ft, 19-second beast from the SW. That’s the one for the crew that wants to get spit out.

Stay tuned, the good stuff is coming.

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.
