The Lowdown

Alright, crew. Rusty here again. Let's break it down in feet and Fahrenheit.

It's a slow-burn start for Dunes. The first few days are a write-off, with Monday, Tuesday, and Wednesday offering next to nothing. You're going to be waiting a few days before the magic shows up.

We finally get a bit of life on Tuesday morning, July 29th. It's small, with waves around 3ft from the SW, but a light offshore breeze will keep it clean. The energy is moderate (305) and it's a long-period groundswell at 14 seconds, so it'll have some shape. But the real corker is the morning of Wednesday, July 30th. That's a glassy morning with 2ft of 17-second groundswell (325). It's not a big wave day, but it will be pure, clean fun for a longboard.

Now, you want to circle Monday, August 3rd. The morning is looking good with a 3ft SW swell and a combined energy of 671, but the afternoon is the real deal. We're looking at 6ft of SW swell with a 13-second period, glassy conditions, and a massive combined energy of 1627. That's a powerful shot of juice. This is a session for experienced surfers only. The waves will have some serious grunt. This reef breaks consistently and is exposed to the SW swell, which is exactly what we want. Just remember, crowds are possible here, so you'll have to share the peak.

Saturday morning, August 1st is also worth a look. You'll get a 4ft SW swell with a 15-second period, and fresh offshore winds (725). It's clean, but a step below the Monday stand-out. The water temp is about 76°, which is pretty average for the season.

The whole run from August 1st to the 4th has some big energy, but Tuesday, August 4th sees the swell building to 7ft (1582) but the wind turns onshore, making it a bit of a mess. It's still a big swell for the experts, but the Monday glass-off is the one to aim for.

Rusty out.

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.
