The Lowdown
Howdy, Rusty here. Let’s break down the next couple of weeks. It starts off flat and frustrating, so don’t rush, but the second week has some real juice if you can wait it out.
The first few days are a total bust. There's a persistent cross-offshore breeze, but the swell is tiny—between 1ft and 3ft—and the wave energy readings are weak, hanging around 100 to 310. The water temp is about 76°, which is normal for this time of year. Surfaces are clean in the mornings, but the surf is classified as poor. Nothing to even look at.
We start to see a pulse arrive on Friday the 31st of July. The afternoon shows a 3ft swell from the SW with a 18-second period. That’s a long-period groundswell, and the energy reading jumps to 575, which is solid. Wind is a gentle cross-shore, so it’s okay, but the surf is still considered marginal.
The real standout begins Saturday the 1st of August. Saturday morning at Dunes is the first solid call. It’s clear, we’ve got a gentle offshore breeze from the SE, and the swell is a clean 3ft from the SW. The period is 16 seconds, so those waves have some push and shape, with an energy reading of 623. This is a consistent reef break, so it’ll be running, but you’ll likely have some company in the water.
The absolute best window hits Monday the 3rd of August. Monday morning is the one. A light offshore wind from the SE, a solid 3ft swell from the WSW with a 16-second period, and the energy reading blows up to 887. That’s the highest clean-swell energy of the run before the big stuff arrives. Conditions are flagged as “very good.” That is your session to circle on the calendar.
After that, the week gets lumpy with mixed winds, but then Friday the 7th of August brings a massive pulse. Swell hits 7ft from the SW with a 17-second period. The wave energy is a beastly 2629. There is a strong offshore wind, but the report warns it may be too big for the break. This is for experts only. Even Saturday the 8th has a solid 5ft swell running, which is still a handful.
Best bet: Monday morning the 3rd of August. Perfect balance of clean conditions, good energy, and quality swell. Saturday the 1st is your back-up plan.
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.
