The Lowdown
Alright folks, Rusty here, checkin’ in with a look at what the next couple of weeks have got cookin’ for us at Dunes.
The long story short? We’re gonna earn it. The first week is a real grind with onshore slop and small, messy waves. There are a few windows where it cleans up, but it’s mostly a waiting game. The real glimmer of hope is right at the end of the fortnight, with a promising session that looks worth circling on the calendar.
We kick off on the 24th of July with nothing really going on. It's onshore, it's bumpy, and you’d be better off doing something else. The mornings are the cleaner part of the day, but with a cross-off breeze and a weak 2ft swell from the SW, it's just not got any push. The combined energy is only around 182, so it's weak. That same script basically plays out on the 25th, 26th, and 27th of July. Mornings have that clean look but with a cross-off wind, yet the swell is tiny and the energy is still well under 200. Afternoons are a no-go.
The 28th of July finally gives us a little bump. The morning sees the swell nudge up to 3ft from the SW with the energy climbing to a moderate 304. It’s still just marginal, but that’s a step up. Wednesday the 29th is more of the same, with clean mornings and a similar sized swell, but the energy is building (350-430). Still, nothing to get too excited about.
Now, Thursday the 30th of July is the first real highlight of the run. We’ve got a clean morning with a 2ft WSW swell but check the period – it’s 17 seconds. That’s proper groundswell energy. The combined energy is a healthy 379, and we get a proper offshore wind from the SE. This is going to be clean, lined-up, and although the swell is small, the quality will make up for it. This is the session for the longboard or a fish.
The end of July and start of August see the swell size slowly climb. On the 31st, the morning is clean but the swell hits just under 4ft from the SW with a 17-second period and the energy jumps to 659. It’s still only rated as marginal, but the potential is there for some fun ones if you can find a bank. By the 1st of August, we’re seeing a solid 4ft SW swell in the morning with energy at 895. The wind is cross-off, so it’s clean, but it’s still just a “maybe” rather than a guarantee.
We hit a bit of a funk from the 2nd to the 4th of August as onshore winds and rain showers move in. The swell sticks around, even getting up to just under 4ft, but with fresh cross-on winds, it’s going to be a messy, lumpy mess. Not worth the paddle.
The big one to watch is Wednesday the 5th of August. The morning is calling for glassy conditions with a 2ft SW swell sporting a 14-second period. The combined energy is a moderate 276, but with zero wind on the water, that little swell is going to be pristine. If you’ve got a log, this is the ultimate cruise session. It’s the standout of the whole forecast.
After that, it gets a bit average again through the 6th and 7th, with the wind turning against us. The 8th of August morning is interesting – the swell jumps to just over 6ft from the SW and the energy is a massive 1462, but it’s cross-shore and messy. That’s a lot of juice, but without clean wind, it’ll just be a washing machine. Kite surfers might be eyeing that one off more than we will.
So, the call? Don't waste your time until the morning of Thursday the 30th of July. That’s a solid little window. After that, mark down Wednesday the 5th of August in the morning for a glassy, beautiful small-wave day. It doesn't get better than that.
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.
