The Lowdown

Alright folks, Rusty here. Let’s talk about what’s cooking at Dunes. This is a solid reef break that needs a good SW groundswell, and we’ve got one rolling in, so let’s get into it.

The first proper window kicks off Thursday morning, August 6th. We’re looking at a clean 5ft SW swell with a long 16-second period—that’s proper groundswell, folks. The wind is a light cross-off from the SSE at 3 mph, keeping things glassy. The combined energy is solid (1158), and the water temp is doing its usual thing for this time of year, nothing wild. This is excellent surf for experienced surfers, so if you’ve got the skill, get out there for the early session. The reef setup will handle that long period nicely.

Friday morning, August 7th, is another standout. The swell drops a touch to 5ft, but it’s still SW at 16 seconds. The wind swings offshore from the SSE at 12 mph, which is a major positive. The energy is still pumping (1125). This is clean, offshore, and the kind of morning that gets your heart pumping. The crowd factor is "sometimes" here, so you might have some company, but it’s worth it.

Sunday morning, August 9th, sees the wind crank up to a fresh offshore from the SE at 22 mph. The swell is 5ft at 15 seconds, but the energy drops and the quality looks marginal. The wind will be strong, so it’s a bit of a battle but still clean.

Now, there’s a rough patch. From Tuesday, August 11th, through to Monday, August 17th, the surf drops way off. The swell heights fall below 3ft, the energy is weak (under 500), and the conditions are mostly poor. There’s a big gap of about a week with nothing worth paddling out for. Hang tight.

Then, hold onto your boards. Tuesday morning, August 18th, is the real deal. The swell jumps to 6ft from the SW, with a 17-second period and a massive combined energy of 1740. The wind is glassy—dead calm—from the ENE at 3 mph. This is a dream setup for experienced surfers: clean, powerful, and long lines. This is the best on offer in the whole run. Get it while it’s hot.

Wednesday morning, August 19th, is also excellent. 6ft SW swell, 16-second period, and a moderate offshore from the SE at 12 mph. The energy is strong (1449), and it’s clean. A solid follow-up session.

The run fades out after that, with Thursday morning, August 20th, offering a last decent 4ft SW swell, but it’s smaller. Friday morning, August 21st, finishes with a glassy 3ft wave, but it’s not much to write home about.

So, the best of the batch is Tuesday morning, August 18th, with that glassy, powerful groundswell. Thursday morning, August 6th and Friday morning, August 7th are also top-tier. The long, empty week in the middle is a bummer, but the forecasts can change. Stay tuned.

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.
